TO:Honorable Mayor and City Councilmembers
FROM:Linda Smith, City Manager
SUBJECT:Energy Services Agreement Amendment with Willdan Energy Solutions for Efficiency and Infrastructure Improvement Projects and Consideration of a Financing PlanPrepared by:Colleen Tribby, Assistant City Manager and Laurie Sucgang,City Engineer
EXECUTIVE SUMMARY:The City Council will consider the implementation of energy efficiency and related infrastructure improvement projectsby approving an amendment to the design-build energy savings performance contract with Willdan Energy Solutions. The City Council will also considerapproval ofthe issuance of tax-exempt bonds to fund the projects and the adoption of a resolution allowing the City to be reimbursed for expenditures on the projects prior to the issuance of bonds.
STAFF RECOMMENDATION:Take the following action: 1) Conduct a Public Hearing and Adopt the Resolution Making Findings Required Under Government Code Sections 4217.10-18 and Approving an Amendment to the Design-Build Energy Savings Performance Contract with Willdan Energy Solutions for Energy Reduction, Core Facility Infrastructure, and Resiliency Upgrades Projects; 2) Receive a report on the proposed financing plan and provide direction to Staff to return with the financing documents at a future meeting; and 3) Adopt the Resolution Declaring Intention to Reimburse Expenditures from the Proceeds of Certain Tax-exempt Obligations and Directing Certain Actions.
FINANCIAL IMPACT:The total cost of the projects proposed through the Investment Grade Audit process is $21,428,950. The Five-Year Capital Improvement Program currently has $2,445,000 ($1,638,665from the General Fund and $806,335 from the East Dublin Street Light District 1999-1 Fund) budgeted in several projects that could be applied to the projects. Funding of all recommended projects would require the City to either utilize $18,983,950 in General Fund Undesignated Reserves in combination with the available CIP funds, or finance the improvements with or without the use of the available CIP funds. Should the City Council desire to finance the projects

via bond issuance, all related costs, including bond and disclosure counsel services, would be covered by bond proceeds, and debt service payments would be paid for solely by the General Fund. These options are discussed under the Financing Plan section of this Staff Report.If all recommended projects are implemented, there is a potential annual savings of $694,000 and a lifetime savings (25 years) of approximately $28,600,000. In addition, there would be no cost for the IGA. If the City Council opts to forgo any of the construction projects, the City will be subject to pay $125,000 for the engineering and design services completed during the IGA phase, or a prorated amount based on the projects that are not implemented.
DESCRIPTION:BackgroundIn the last several years, the City has taken steps toward increasing resiliency to become better prepared for emergency events such as Pacific Gas & Electric Company’s Public Safety Power Shutoff events in October of 2019 and 2020. More recently, the City has taken steps towardmeeting its Climate Action Plan goals and addressing core infrastructure needs. Specifically, the City has taken the following actions:
On June 9, 2020, the City Council adopted the Five-Year Capital Improvement Program (Resolution No. 54-20) which included funding of the Resiliency and Disaster Preparedness Improvements project, Citywide Energy Improvements project, and the Solar Photovoltaic Canopies at The Wave project.
On September 15, 2020, the City Council adopted the Climate Action Plan 2030 and Beyond(CAP 2030), which identified Dublin’s plan to significantly reduce carbon emissions by 2030 and includes the goal of reaching carbon neutrality by 2045.
In response to the State law transitioning California’s transportation sector to zero carbon emissions by 2035 (Executive Order N-79-20 of September 2020), Staff has been developing a plan to transition the City’s fleet of internal combustion engine vehicles to battery-electric vehicles and is looking for opportunities to install infrastructure for electric vehicle charging for the fleet vehicles.
On November 17, 2020, the City Council approved a design-build energy savings performance contract with Willdan Energy Solutions, to prepare an Investment Grade Audit (Resolution No. 115-20).
On June 1, 2021, the City Council received a report on the recommended projects from the Investment Grade Audit, discussed financing options, and provided direction to Staff.Energy Services ContractWilldan has now completed Phase 1 of the performance contract, resulting in the Investment Grade Audit Report (IGA). An IGA includes an in-depth analysis of the financial aspects of energy savings and the return on investment from potential changes or upgrades to City facilities that are in alignment with resiliency goals, getting the City closer to meeting its Climate Action Plan goals, and addressing core infrastructure needs, while considering how each project may improve the facility’s service and role in the City’s Emergency Operations Plan and the Tri-Valley Local Hazard Mitigation Plan.

The recommended projects resulting from the IGA were presented to the City Council on June 1, 2021 and are now fully designed and engineered. The scopes of work of the projects generally include replacement of aged and maintenance-intensive heating, ventilation, and air conditioning (HVAC) systems, upgrading of facilities to web-based and wireless controls, converting facility, landscape and park lighting to light-emitting diode (LED) systems with controls, installation andreplacement of back-up generators, installation or upgrade of back-up power systems at 22 traffic signal intersections, installation of one megawatt of solar photovoltaic (PV) systems at multiple sites, and installation of power resiliency systems with batteries and generators. A summary of the projects was provided in the June 1, 2021 Staff Report (Attachment 4) and detailed in the IGA (Attachment 5). The list of projects was narrowed down from a larger initial list, and only the most economical, critical, and beneficial scopes of work and projects were proposed by Willdan in consultation with Staff.Phase 2 is project implementation. Approval of the amendment to the performance contract will allow Staff to work with Willdan to implement improvements totaling $21,428,950, resulting in long-term savings to the City of approximately $28,600,000. Project prioritization is based on: (1) resiliency and disaster preparedness (for things like PG&E Public Safety Power Shutoff events), (2) replacement of aged and maintenance-intensive equipment, (3) utility bill savings, and (4) energy savings and carbon reduction in alignment with the CAP 2030.The proposed amendment to the performance contract provides for the guaranteed savings for three years. Willdan will pay for any annual shortfall as indicated in the amendment. Within the IGA Baseline Utility Analysis, Willdan has established a detailed utility baseline for how each facility and park operates. This shows existing conditions and allowed Willdan to create energy models to achieve realistic utility savings that will be seen after the projects are completed, which Willdan will stand behind for the guaranteed savings performance period.Cost savings are based on reduced utility bills from less energy usage and the reduced cost to operate and maintain the equipment. In instances where the equipment is new, the savings is net of the added cost to operate and maintain the new equipment. No added operations and maintenance costs were included for existing equipment being replaced, as the City has already budgeted for these. The energy savings, maintenance savings, and total annual savings for each category of projects is summarized in the table below.

TOTAL $ 21,428,950 $ 437,953 $ 570,055 $ 124,013 $ 694,068 To guarantee the energy savings and investment in the various energy reductions, core facility infrastructure and resiliency upgrades, Staff recommends a measurement and verification term of three years, in contrast to the standard one-year term. Details of the measurement and verification plan are provided in Appendix E of the IGA (Attachment 5).Once complete, the projects will result in an estimated 3% reduction in greenhouse gas (GHG)emissions for the City, which aligns with the CAP 2030 goals. Although the impact of the projects on total GHG emissions is relatively small, these investments would provide guidance to the community on how energy efficiency and resiliency projects can be incorporated into existing buildings and infrastructure. Achieving the deep GHG emissions reductions required to reach the goal of carbon neutrality by 2045 described in the CAP 2030 will require action and participation by the entire community. Implementation of these projects would demonstrate the City’s commitment to reaching the CAP 2030 goals in conjunction with asking residents to implement their own projects or make lifestyle adjustments to help achieve greater GHG emissions reductions. If approved, it is anticipated that the total construction project will take approximately 12 months for substantial completion of all projects. There may be an additional three-to-six months for the solar photovoltaic systems to go live due to coordination with PG&E for interconnection to the electric grid. Financing PlanThe total cost of $21,428,950 is the “turnkey” cost, which includes design and engineering, subcontracts, utility program and grant management as applicable, permits and fees, construction management and field supervision, operations and maintenance support, measurement and verification, and guaranteed savings for the selected term.

The City Council has three options available to fund the projects:1) Capital Improvement Program and General Fund Reserves. The existing CIP includes $2,445,000 allocated to various energy efficiency projects, funded by the General Fund and the East Dublin Street Light District 1999-1 Fund. To fund all the projects identified in the IGA, an additional $18,983,950 would need to be allocated from General Fund Reserves. This would result in an estimated ending balance of $43,069,079 in the General Fund Unassigned Cash Flow Reserve, which equates to six months of the adopted Fiscal Year 2021-22 Budget. Based on the existing levels of reserves, uncertainty due to the COVID-19 pandemic, and future capital project funding needs or other potential fundingcommitments, this option is not recommended.2) Tax-Exempt Bond Issuance (Public Placement). The City could issue tax-exempt Lease Revenue Bonds to fund all the projects identified in the IGA. The City would secure an underlying credit rating (assume an AA rating from Standard and Poor’s) and issue bonds in the public market at a time when interest rates are at historically low levels. The bondswould be an obligation of the City’s General Fund and could be repaid over a 25-year term(as an example). Annual debt service for a bond issuance of the total project amount is estimated at roughly $1,124,000, totaling $28,100,000 over the 25-year period.Advantages of bond issuance include lower interest rates, longer maturities than a private placement (up to 30 years), and the fact that it is the most common form of debt issuance.Some drawbacks to bond issuance include the higher cost of issuance, a longer time needed to complete the transaction, staff time needed to prepare the required documentation, the need to provide annual disclosures, the requirement of a credit rating, and less flexible call provisions.3) Tax-Exempt Lease Purchase Agreement (Private Placement). The City could enter into a tax-exempt Lease Purchase Agreement (LPA) to fund all the Projects identified in the IGA. The City could repay the LPA over a 15-year term with a bank as a Private Placement.Annual debt service for the total project amount is estimated at roughly $1,700,000, totaling $25,500,000 over the 15-year period.Advantages of the Private Placement include low cost of issuance, no initial or annual continuing disclosure, no credit rating necessary, a relatively quick process, and more flexible call features. Drawbacks to a Private Placement include higher interest rates, the potential for onerous negotiations, the requirement of formal credit approval from the bank before the rate is locked, the fact that such arrangements are not always available, and the short-term nature of the placement (typically 10 to 15 years)Based upon the review of the advantages and drawbacks of both financing mechanisms, and particularly the lower annual debt service costs for tax-exempt bonds, Staff is recommending that the City Council authorize proceeding with a bond issuance in the public market. Regarding the potential use of the budgeted CIP funds ($2,445,000), Staff recommends that theGeneral Fund portions of those projects ($1,638,665) be freed up and replaced with bond

proceeds. The portion of the projects funded by the East Dublin Street Light District 1999-1 Fund($806,335) would remain allocated to the projects, as this is a non-General Fund source that was collected for the purpose of such improvements. This would result in a total bond issuance of $20,622,615. Note that the debt service amounts in this Staff Report were prepared with the slightly higher bond issuance amount. This final bond documents (anticipated in September) will reflect the actual bonds total.City Council Actions NeededShould the City Council direct Staff to pursue issuance of tax-exempt bonds, the first step is approval of a resolution (Attachment 6) that will enable the City to be reimbursed from bond proceeds for any expenditures related to the projects prior to the issuance of the bonds. A reimbursement resolution is the required expression of intent to issue bonds and is needed forthe City to reimburse itself subject to certain limitations. Note that the resolution is not required for reimbursement of soft costs, however it is good practice to adopt the resolution well in advance of the expenditure of hard costs. Future ActionsAfter tonight’s approval, the Staff anticipates undertaking the following steps to issue the bonds:
Prepare required legal documents and identify the asset(s) to be pledged to secure thebonds in August
Prepare required financing documents including the Preliminary Official Statement and Continuing Disclosure Certificate in August
Secure an underlying credit presentation from Standard & Poor’s in September
Return to the City Council in September for approval of all required documents
Price and close bonds in OctoberCalifornia Environmental Quality Act AnalysisStaff has reviewed the proposed action and recommends the City Council determine that the Project is exempt from the California Environmental Quality Act (CEQA, Sections 21000, et seq. of the California Public Resources Code) as follows: (i) Categorical Exemption Class I (CEQA Guidelines Section 15301) applies to the minor alteration of existing public facilities, including operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, involving negligible or no expansion of use beyond that existing at the time of the lead agency’s determination; (ii) Class 3 (CEQA Guidelines Section 15303) consists of construction and location of limited numbers of new, small facilities or structures; installation of small new equipment and facilities in small structures; and the conversion of existing small structures from one use to another where only minor modifications are made in the exterior of the structure; and (iii) none of the exceptions in CEQA Guidelines Section 15300.2 are applicable.

Section 16.1 Actions by WES: WES shall provide all service, repairs, and adjustments to the Equipment Installed under terms of
this Contract pursuant to SCHEDULE G.4 (WES Maintenance Responsibilities), provided as part the Performance
Contract Amendment (EXHIBIT 1). Customer shall incur no cost for Equipment service, repairs, and adjustments,
except as set forth in SCHEDULE B (COMPENSATION TO WES), provided, however, that when the need for
maintenance or repairs principally arises due to the negligence or willful misconduct of the Customer or any employee
or other agent of Customer, and WES can so demonstrate such causal connection, WES may charge Customer for the
actual cost of the maintenance or repair insofar as such cost is not covered by any warranty or insurance proceeds.
Section 16.2 Malfunctions and Emergencies: Customer shall use its best efforts to notify WES or its designee(s) within 24 hours
after the Customer’s actual knowledge and occurrence of: (i) any malfunction in the operation of the Equipment or
any preexisting energy related equipment that might materially impact upon the guaranteed energy savings, (ii) any
interruption or alteration to the energy supply to the Premises, or (iii) any alteration or modification in any energy-
related equipment or its operation.
Section 16.3 Where Customer exercises due diligence in attempting to assess the existence of a malfunction, interruption, or
alteration it shall be deemed not at fault in failing to correctly identify such conditions as having a material impact
upon the guaranteed energy savings. Customer shall notify WES within twenty-four (24) hours upon its having actual
knowledge of any emergency condition affecting the Equipment. WES shall respond or its designee(s) shall respond
within twenty-four (24) hours to promptly proceed with corrective measures. Any telephonic notice of such conditions
by Customer shall be followed within three business days by written notice to WES from Customer. If Customer

changes or new procedures shall be the responsibility of WES.
Section 17.2 All modifications, additions or replacements of the Equipment or revisions to operating or other procedures shall be
described in a supplemental Schedule(s) to be provided to the Customer for approval, which shall not be unreasonably
withheld, provided that any replacement of the Equipment shall be new and have equal or better potential to reduce
energy consumption at the Premises than the Equipment being replaced. WES shall update any and all software to be
used in connection with the Equipment in accordance with the provisions of Section 14.1 (Ownership of Certain
Proprietary Rights). All replacements of and alterations or additions to the Equipment shall become part of the
341
City of Dublin : Energy Savings Performance Contract | Page 6
Equipment described in SCHEDULE A (SCOPE OF WORK) and shall be covered by the provisions and terms of
SECTION 9 (CONSTRUCTION SCHEDULE AND EQUIPMENT INSTALLATION; APPROVAL).
SECTION 18 STANDARDS OF COMFORT
Section 18.1 WES will maintain and operate the Equipment in a manner that will provide the standards of heating, cooling, hot
water, and lighting, as described in SCHEDULE G.3 (Standards of Comfort) , provided as part the Performance
Contract Amendment (EXHIBIT 1).
SECTION 19 MATERIAL CHANGES
Section 19.1 Material Changes Defined: A Material Change shall include any change in or to the Premises, whether structural,
operational or otherwise in nature which reasonably could be expected, in the judgment of the Customer, to increase
or decrease annual energy consumption in accordance with the provisions and procedures set forth in SCHEDULE E
(BASELINE ENERGY CONSUMPTION) and SCHEDULE F (SAVINGS MEASUREMENT & CALCULATION
FORMULAE; METHODOLOGY TO ADJUST BASELINE) , provided as part the Performance Contract
Amendment (EXHIBIT 1), by at least 0.5% after adjustments for climatic variations. Actions by the Customer which
may result in Material Change include but are not limited to the following:
x manner of use of Premises by the Customer; or
x hours of operation for the Premises or for any equipment or energy using systems operating at the Premises; or
x permanent changes in the comfort and service parameters set forth in SCHEDULE G.3 (Standards of Comfort)
, provided as part the Performance Contract Amendment (EXHIBIT 1); or
x occupancy of the Premises; or
x structure of the Premises; or
x types and quantity of equipment used at the Premises; or
x modification, renovation or construction at the Premises; or
x the Customer’s failure to provide maintenance of or repairs to the Equipment in accordance with SCHEDULE
G.5 (Customer Maintenance Responsibilities) , provided as part the Performance Contract Amendment
(EXHIBIT 1); or
x any other conditions other than climate affecting energy use at the Premises.
Section 19.2 Reported Material Changes: Notice by Customer: The Customer shall use its best efforts to deliver to WES a written
notice describing all actual or proposed Material Changes in the Premises or in the operation of the Premises at least
30 days before any actual or proposed Material Changes is implemented or as soon as is practicable after an
emergency or unplanned event. Notice to WES of Material Changes which result because of a Bona Fide emergency
or other situation which precludes advanced notification shall be deemed sufficient if given by the Customer within
48 hours after having actual knowledge that the event constituting the Material Change occurred or was discovered
by the Customer to have occurred.
Section 19.3 Unreported Material Change: In the absence of any Material Changes in the Premises or in their operations, the
baseline energy consumption as set forth in SCHEDULE E (BASELINE ENERGY CONSUMPTION) , provided as
part the Performance Contract Amendment (EXHIBIT 1), should not change more than 2% during any month from
the projected energy use for that month, after adjustments for changes in climate conditions. Therefore, if energy
consumption for any month as set forth in SCHEDULE E (BASELINE ENERGY CONSUMPTION) deviates by
more than 2% from the energy consumption of the same month of the preceding contract year after adjustments for
changes to climatic conditions, then such deviation shall be timely reviewed by WES to ascertain the cause of
deviation. WES shall report its findings to the Customer in a timely manner and WES shall determine what, if any,
adjustments to the baseline will be made in accordance with the provisions set forth in SCHEDULE F (SAVINGS
MEASUREMENT & CALCULATION FORMULAE; METHODOLOGY TO ADJUST BASELINE) and
SCHEDULE E (BASELINE ENERGY CONSUMPTION) , provided as part the Performance Contract Amendment
(EXHIBIT 1).
SECTION 20 INDEMNIFICATION
Section 20.1 WES shall indemnify, defend with counsel acceptable to Customer, and hold harmless Customer and its officers,
elected officials, employees, agents and volunteers from and against any and all liability, loss, damage, claims,
342
City of Dublin : Energy Savings Performance Contract | Page 7
expenses, and costs (including without limitation, attorney’s fees and costs and fees of litigation) (collectively,
“Liability”) of every nature arising out of or in connection with WES’s performance of the services called for or its
failure to comply with any of its obligations contained in this Agreement, except such Liability caused by the sole
negligence or willful misconduct of the Customer.
Section 20.2 Notwithstanding the forgoing, to the extent this Agreement is a “construction contract” as defined by California Civil
Code Section 2782, as may be amended from time to time, such duties of WES to indemnify shall not apply when to
do so would be prohibited by California Civil Code Section 2782.
Section 20.3 WES’s obligation to defend and indemnify shall not be excused because of WES’s inability to evaluate Liability or
because WES evaluates Liability and determines that WES is not liable to the claimant. WES must respond within
thirty (30) days to the tender of any claim for defense and indemnity by Customer. If WES fails to accept or reject a
tender of defense and indemnity within thirty (30) days, in addition to any other remedy authorized by law, so much
of the money due WES under and by virtue of this Agreement as shall reasonably be considered necessary by
Customer, may be retained by Customer until disposition has been made of the claim or suit for damages, or until
WES accepts or rejects the tender of defense, whichever occurs first.
SECTION 21 CONDITIONS BEYOND CONTROL OF THE PARTIES
Section 21.1 If a party (“performing party”) shall be unable to reasonably perform any of its obligations under this Contract due
to acts of Nature, insurrections or riots, or similar events, this Contract shall at the other party’s option (i) remain in
effect but said performing party’s obligations shall be suspended until the said events shall have ended; or, (ii) be

Section 40.1 To encourage the implementation of a more energy-efficient system, Section 179D of the Internal Revenue Code
provides for the allocation of a tax deduction based on the efficiency of the design. Since a public entity is exempt
from paying taxes, the Code permits this allocation to be passed along to the designer of the system as an additional
incentive to incorporate the most efficient system affordable. Accordingly, once the building/system is placed into
service, it is understood and agreed that the tax deduction granted pursuant to Section 179D of the Internal Revenue
Code will be allocated to Willdan, in consideration of which Willdan will use its best efforts to maximize the energy
efficiency of the design being contracted.

Until the Project is complete, as identified as a line item in the Schedule of Values, Customer will pay ninety-five
percent (95%) of the amount due to WES on account of progress payments for each line item. This 5% retention shall
be reduced, if appropriate, in conjunction with Substantial Completion to reflect incomplete work for each line item.
Complete payment of retention shall be in conjunction with Acceptance of Project Completion for each Project
identified in the Schedule of Values, which shall not be unduly withheld.
(4) Schedule of Values: WES will prepare and submit a complete schedule of values along with initial Application for
Payment. Projects listed as line items in the Schedule of Values will be treated as individual projects for the purposes
of Progress Payments, Substantial Completion, Final Completion, and withholding of retention amounts.
(5) Substantial Completion: Substantial Completion is the stage in the progress of the Project when the Project or
designated portion thereof is sufficiently complete in accordance with the Contract Documents so that the Customer
can utilize the Work for its beneficial use.
When WES considers that an individual Project is substantially complete, WES shall prepare and submit to the
Customer a comprehensive list of items to be completed or corrected prior to final payment. Upon receipt of WES's
list, the Customer shall, within seven days, inspect the Work to formulate the Customer’s Punch List and to determine
whether the Work or designated portion thereof is substantially complete. If the Customer’s inspection discloses any
item, whether or not included on WES's list, which is not sufficiently complete in accordance with the Performance
Contract Documents so that the Customer can utilize the Project or designated portion thereof for its intended use,
WES shall, before issuance of the Certificate of Substantial Completion, complete or correct such item upon
notification by the Customer. In such case, WES shall then submit a request for another inspection by the Customer
to determine Substantial Completion.
When the Work or designated portion thereof is substantially complete, WES will prepare a Certificate of Substantial
Completion which shall establish the date of Substantial Completion, shall establish responsibilities of the Customer
and WES for security, maintenance, heat, utilities, damage to the Project and insurance, and shall fix the time within
which WES shall finish all items on the list accompanying the Certificate. Warranties required by the Contract

otherwise provided in the Certificate of Substantial Completion. The Certificate of Substantial Completion shall be
submitted to the Customer for their written acceptance of responsibilities assigned to them in such Certificate.
(6) Substantial Completion Payment: Upon Substantial Completion acceptance, the Customer shall make payment of
retainage applying to such Work or designated portion thereof within the time provided in Section 7.3. Such payment
shall be reasonably adjusted to reflect the dollar value of Work that is incomplete or not in accordance with the
requirements of the ESPC Documents.
(7) Project Completion and Payment: After WES’s completion of all punch list items, project closeout requirements, and
upon receipt of written notice that the Project is ready for final inspection and acceptance and upon receipt of a Final
Application for Payment, the Customer will make such inspection within seven days and, when the Customer finds
the Project acceptable under the Contract Documents and the Contract fully performed, the Customer will execute
and issue the Certificate of Acceptance within two days from the final inspection and pay the entire balance found to
be due to WES as stated in the Final Application for Payment within the time provided in Section 7.3.

STAFF REPORT
CITY COUNCIL
Page 1 of 6
Agenda Item 8.1
DATE:June 1, 2021
TO:Honorable Mayor and City Councilmembers
FROM:Linda Smith, City Manager
SUBJECT:Energy Efficiency and Infrastructure Improvement Projects
Prepared by: Laurie Sucgang, City Engineer
EXECUTIVE SUMMARY:
The City Council will consider the implementation of energy efficiency and related infrastructure
improvement projects. The City Council will also consider authorizing Staff to explore funding for
the projects, which may include bond issuance or other financing, which would be brought back to
the City Council for final approval.
STAFF RECOMMENDATION:
Receive a report summarizing the recommended Energy Efficiency and Infrastructure
Improvement Projects resulting from the Investment Grade Audit conducted by Willdan Energy
Solutions and provide direction to Staff on project implementation and the exploration of project
funding.
FINANCIAL IMPACT:
As approved in the 2020-2025 Capital Improvement Program (CIP), there is approximately
$2,445,000 allocated towards various projects that include all or portions of the energy efficiency
projects presented in this report: Citywide Energy Improvements Project (CIP No. GI0121),
Resiliency and Disaster Preparedness Improvements Project (CIP No. GI0221), Dublin Ranch
Street Light Improvements Project (CIP No. ST0417), Solar Photovoltaic Canopies at The Wave
(CIP No. GI0321), and the Library Tenant Improvements Project (CIP No. GI0002).
On November 17, 2020, the City Council approved a design-build energy savings contract with
Willdan Energy Solutions, to prepare an Investment Grade Audit (IGA) that includes proposed
construction projects that will achieve energy savings and facility improvements. If the City
Council chooses to proceed with construction of any of the energy efficiency projects, there is no
cost for the IGA. If the City Council opts to forgo any of the construction projects, the City will be
subject to pay $125,000 for the engineering and design services completed during the IGA phase.
The total cost of the projects proposed through the IGA process is approximately $21,226,500. If
1415
Attachment 4
364
Page 2 of 6
all projects are constructed, there is a potential annual savings of $693,900 and a lifetime savings
(25 years) of $25,900,000. Taking into account the $2,445,000 of funding within the CIP,
approximately $18,800,000 of additional funding is necessary to construct all the projects.
Options for funding the projects are presented in the Funding and Financing Options section near
the end of the Staff Report.
DESCRIPTION:
Background
In the last several years, the City has taken steps toward increasing resiliency to become better
prepared for emergency events (such as PG&E’s Public Safety Power Shutoff events in October of
2019 and 2020), and more recently, to meeting its Climate Action Plan goals and addressing core
infrastructure needs.
Specifically, the City has taken the following actions:
On June 9, 2020 the City Council adopted the Five-Year Capital Improvement Program
(Resolution No. 54-20) which included the Resiliency and Disaster Preparedness
Improvements project, Citywide Energy Improvements project, and the Solar Photovoltaic
Canopies at The Wave project.
On September 15, 2020 the City Council adopted the Climate Action Plan 2030 and Beyond
(Climate Action Plan), which identified Dublin’s plan to significantly reduce carbon
emissions by 2030 and the goal of reaching carbon neutrality by 2045.
In response to the State law transitioning California’s transportation sector to zero
emissions by 2035 (Executive Order N-79-20 of September 2020), Staff has been
developing a plan to transition the City’s fleet of internal combustion engine vehicles to
battery-electric vehicles and looking for opportunities to install infrastructure for electric
vehicle charging for the fleet vehicles.
On November 17, 2020 the City Council approved a design-build energy savings contract
with Willdan Energy Solutions, to prepare an Investment Grade Audit (Staff Report
included as Attachment 1).
Investment Grade Audit
The Investment Grade Audit (IGA) prepared by Willdan provides an in-depth analysis of the
financial aspects of energy savings and the return on investment from potential changes or
upgrades to City facilities that are in alignment with resiliency goals, as well as getting the City
closer to meeting its Climate Action Plan goals and addressing core infrastructure needs. The
project is separated into two main phases: Phase 1 is project development, which is substantially
complete, and Phase 2 is implementation of selected projects.
This Staff Report presents the results of Phase 1, the identification of projects recommended for
the implementation phase, Phase 2, and asks the City Council to provide direction on next steps.
In addition to energy savings and cost savings, many of the proposed projects Staff and Willdan
also considered how each project may improve the facility’s service and role in the City’s
Emergency Operations Plan and the Tri-Valley Local Hazard Mitigation Plan.
1416365

Results of Phase 1 – Identified Projects
The scopes of work of the identified projects generally include replacement of aged and
maintenance-intensive heating, ventilation, and air conditioning (HVAC) systems, upgrading of
facilities to web-based and wireless controls, converting facility and park lighting to light-emitting
diode (LED) systems, installation or replacement of back-up generators, installation or upgrade of
back-up systems at 23 traffic signal intersections, installation of one megawatt of solar
photovoltaic (PV) systems at multiple sites, and installation of resiliency systems with batteries
and generators.
The summary below separates projects into three general categories and indicates if they are a (1)
planned Capital Improvement Project (CIP), (2) replacement of equipment at the End of its Useful
Life (EUL), (3) Energy Efficiency and Resiliency project (EE), and/or (4) an improvement or goal
identified in the Climate Action Plan (CAP).
The total cost in each category is the “turnkey” cost, which includes design and engineering,
subcontracts, utility program and grant management as applicable, permits and fees, financing
support as needed, construction management and field supervision, operations and maintenance
support, measurement and verification, and guaranteed savings for the selected term.
Renewable, Resiliency, and Disaster Preparedness Projects
The total cost of projects in this category is approximately $12,715,500. These costs are based on
actual bids from contractors solicited in February and March 2021.

systems, as needed, and wireless controls system; EUL, EE
Funding and Financing Options
There are multiple options to fund public projects; three of the most common are provided below.
Staff recommends doing projects in a comprehensive manner rather than piecemeal to take
advantage of economies of scale, to benefit from energy and cost savings immediately, to lock in
the competitive bid prices received earlier this year in anticipation of increases in construction
costs, and to take advantage of low interest rates.
1419368
Page 6 of 6
1.Capital Outlay - As approved in the 2020-2025 CIP, there is approximately $2,445,000
allocated towards various projects that include all or portions of certain energy efficiency
projects. The total cost of the projects is approximately $21,226,500. For the City to fully
fund the projects, an additional $18,871,500 would need to be allocated from the City’s
General Fund Reserves.
2.Bond Issuance – The City may explore the use of a revenue bond to finance all or some of
the projects. Current interest rates for a 25-year term lease-revenue bond are between 2%
and 3%. Factors for consideration include the City’s credit rating, the value of holding on to
cash now, and the ability for the City to make annual debt service payments.
3.Tax Exempt Lease-Purchase Agreement –Leasing energy-related improvements,
especially the use of tax exempt lease-purchase agreements for energy efficient-equipment,
is a common and cost-effective way for state and local governments to finance upgrades
and then use the energy savings to pay for the financing cost. Leases often have slightly
higher rates than bond financing but can be a faster and more flexible option.
Dublin has some experience with lease financing. In 2012, the City entered into an Energy
Services Contract with Chevron Energy Solutions for various energy related improvements
and utilized the lease financing option, in addition to the contribution of Internal Service
Fund reserves. The lease amount was $6,928,772 and the projected interest was
$1,381,055. In 2018, the City opted to pay off the lease early.
If the City Council chooses to proceed with construction, Staff recommends that the City Council
direct Staff to further evaluate the funding options listed above and bring forward a
recommendation on the best way to proceed.
STRATEGIC PLAN INITIATIVE:
None.

STAFF REPORT
CITY COUNCIL
DATE: November 17, 2020
TO: Honorable Mayor and City Councilmembers
FROM:
Linda Smith, City Manager
SUBJECT:
Contract with Willdan Energy Solutions for an Investment Grade Audit
Prepared by: Laurie Sucgang, City Engineer
EXECUTIVE SUMMARY:
The City Council will consider approving a contract with Willdan Energy Solutions to
proceed with an Investment Grade Audit to develop energy efficiency and infrastructure
improvement projects.
STAFF RECOMMENDATION:
Adopt the Resolution Approving a Design-Build Energy Savings Performance Contract
with Willdan Energy Solutions.
FINANCIAL IMPACT:
There is no direct financial impact associated with the agreement at this time. Fiscal
impacts related to specific energy efficiency measures or infrastructure improvement
projects may be brought forward to the City Council for consideration upon completion
of the Investment Grade Audit (IGA). If the City does not move any projects into
construction, the City will be subject to pay $125,000 for the engineering and design
services completed during the IGA phase. Should the City move any projects into
construction, the City will not pay for the IGA phase. All proposed projects will be
evaluated to maximize savings of utility and operational costs.
If applicable, the cost of these services will be paid for in accordance with the adopted
annual budgets in the 2020-2025 Capital Improvement Program for the Citywide Energy
Improvements Project (CIP No. GI0121) and the Resiliency and Disaster Preparedness
Improvements Project (CIP No. GI0221).
DESCRIPTION:
The Public Works Department utilizes consultants on Capital Improvement Program
(CIP) projects. Services provided assist Staff in specific areas of technical and
professional expertise. Consultants are solicited through an open and competitive
370
Page 2 of 3
request for qualifications (RFQ) or request for proposals (RFP) process. The RFQ/RFP
processes are used to identify consulting firms and contractors with the necessary
background and experience to provide services and to ensure that the cost for services
is competitive. The RFQ/RFPs specify that selection would be based on quality and
completeness of submissions as well as a firm's experience with engagements of
similar scope and complexity. RFQ/RFPs were sent to firms and vendors previously
under contract with the City and to those that had expressed interest in receiving
RFQ/RFPs. The RFQ/RFPs were also posted on the City's website.
On September 23, 2019, the City issued an RFP for Citywide Energy Upgrades, which
included the development and implementation of approved projects coming from an
Investment Grade Audit (IGA). Nine proposals were received from the following firms:
1. NV5/Celtic
2. Schneider Electric
3. Partner Energy
4. SYSERCO
5. Willdan Energy Solutions
6. Information & Energy Solutions
7. EMG
8. ENGIE
9. OPTONY
After review of the proposals, Staff invited ENGIE, SYSERCO, Schneider Electric, and
Willdan Energy Solutions to interview and present their capabilities. Willdan Energy
Solutions was selected based upon its performance at the interview, its experience and
qualifications, and the qualifications of the individuals on their project team.
The IGA will contain a series of Energy Savings Measures (ESMs) and Facility
Improvement Measures (FIMs). The program is separated into two phases, each with
several distinct elements. The first phase is project development and the second phase
is implementation of the identified projects.
The components of the project development phase are incorporated into the design-
build energy savings performance contract and involve several stages of review of the
City’s assets. The IGA will provide an in-depth analysis of City property and facilities
and will be conducted to an industry standard level of detail to get competitive pricing on
subcontracted work. The audits are used to identify ESMs at an investment grade level,
meaning the degree of certainty in the savings associated with projects is high at the
completion of this stage.
The completion of the IGA will result in one or more groupings or packages/phases of
ESMs and FIMs that are feasible for the City to implement. The components of the
project implementation phase will be incorporated into one or more Energy Services
Contracts. Staff will return to the City Council at a subsequent date to request approval
of any Energy Services Contracts.

Existing Facility Conditions
Willdan’s licensed professional engineers, architects and construction managers
carefully examined the facility systems and condition at each property in the list shown
in the previous section. The information gathered was used to make improvement
recommendations. This section is the written result of that analysis.
Civic Center
General Overview
The Civic Center Admin and former Police Services buildings were constructed in 1989
and underwent remodeling in 2002. The facility is composed of two semi-circular
buildings that serve administration on one side and a soon to be remodeled Cultural
Arts Center on the other side. The Cultural Arts Center side used to serve Dublin’s police
force, however with the opening of a separate Police/Public Safety Complex facility in
the city, the police staff, and all subsequent vehicles and equipment have been
relocated. The administration building is a two-story, 32,633 square foot structure that
contains the City’s administrative offices, City Hall, City Council Chambers, and the
Regional Meeting Room. Currently, the administration building is open Monday through
Friday 8:00am to 5:00pm. With the Cultural Arts Center remodel, the adjacent parking
lot will be reconfigured to accommodate Dublin city vehicle fleet parking and EV
charging.
Building Envelope
The structure’s construction features masonry-bearing walls with metal decks. No
deficiencies were discovered or need to be addressed.
Electrical Systems
There is a 370-kW solar photovoltaic (PV) system in the Civic Center and Library parking
lot installed in 2012 that offsets approximately 48% of the site’s annual electrical
consumption. A 450kW diesel generator was installed in 2012 and serves the Civic
Center building. The generator was sized and installed to also serve the Library’s
electrical loads in an emergency, but the underground electrical connection to the
Library electrical room was not completed at the time of installation.
Willdan has collaborated with the City to identify other factors in the development of
the Civic Center. The City intends to reconfigure the secure parking lot that formerly
served the Police Services wing of the Civic Center building. The City estimates that the
construction will occur in late 2021, and the lot may likely be joined with the rest of the
Civic Center Parking area. Future load growth due to the Cultural Arts Center and
future electric vehicle (EV) fleet charging will occur in the coming years.

| Investment Grade Engineering Audit | Page 11
Lighting Systems
The electricity in the buildings is supplied to a main switchboard (MSB) and distributed to sub-panels for electrical
plug lights, HVAC and lighting circuits. The building’s lighting system consists of a combination of fluorescent T5
lamps, light emitting diode (LED) fixtures, and compact fluorescent lamps (CFLs). With the current HVAC and roof
replacement project, there are also lighting upgrades. The Civic Center does not currently have occupancy-based
lighting controls, which indicates that lights may stay on even if the space is unoccupied.
Mechanical & HVAC Systems
The primary source of heating and cooling for the two buildings are packaged DX Carrier variable air volume (VAV)
rooftop units (RTU) with gas reheat that are approximately 19 years of age and have an expected life of 15 years.
This type of system varies the airflow at a constant temperature, which allows for better temperature control in the
building’s individual zones. Supplementing the packaged units are ductless split-systems and wall-mounted heat
pumps. Domestic hot water (DHW) for the administration building and former Police Services side of the Civic
Center is produced by an aging, roof mounted, 80% efficient atmospheric gas boiler and stored in a nearby
insulated tank. This is the current system before the HVAC renovation that is currently underway.
Energy Management Systems
The existing building automation system (BAS) is by Reliable Controls. The system shows the buildings split into the
zones each RTU serves, with the ability to schedule their hours of operation. The graphical user interface shows
individual zone temperatures and system schematics. With the current renovation the building is undergoing, the
City plans on installing a more modern version of the same Reliable Control system to provide temperature and
comfort control of the new mechanical systems. Willdan recommends that all building’s control systems eventually
be phased to a single platform for consistency and ease of maintenance.

Dublin Library
General Overview
The Dublin Library is located at 200 Civic Plaza and was constructed in 2001, with a
38,898 square foot footprint. This facility is part of the Alameda County Library system
and provides services to the Dublin community for all ages. The facility is open Monday
through Thursday 10:00am to 8:00pm, Saturday 10:00am to 5:00pm, and Sunday 1:00pm
to 5:00pm.
Building Envelope
The single-story structure is composed of a steel frame with concrete-topped metal
decks. The roofs are composed of white modified bitumen material that help reflect,
rather than absorb, solar heat gain. Due to the building’s age, the roof should be either
replaced or patched and upgraded to support any future installations, such as an array
of solar PV, to serve as an expansion to the existing parking lot systems.
Electrical Systems
The main switchboard (MSB) that supplies electricity to the building is a 480Y/277V, 3-
phase, 4-wire board with a 1,200-amp service. The generator at the Civic Center was
sized and installed to also serve the Library’s electrical loads in an emergency, but the
underground electrical connection to the Library electrical room was not made at the
time of installation. This means that the Library does not have emergency backup
power available to energize critical equipment such as lighting and HVAC during a
power outage.
The Library has a 132-kW solar PV carport array that offsets approximately 36% of the
site’s electrical consumption. With the PV installed in the Library parking lot serving both
the Library and Civic Center, there is no remaining carport space available to add
additional PV in the parking lots. Any additional PV would need to be roof mounted, as
described in the Dublin Library’s Energy Conservation Measures section.
Lighting Systems
The building’s interior lighting consists of various lighting technologies, such as
fluorescent T5s and T8s lamps, CFLs, Metal Halide, and LEDs. The non-LED lamps are an
outdated technology that are less energy efficient and have a shorter life than LEDs.
Mechanical & HVAC Systems
The Library has five Trane packaged rooftop units that supply conditioned air to 21 VAV
boxes located downstream. The VAV boxes modulate their dampers to maintain their
respective space temperature setpoints. The RTUs range in capacity from 17.5 to 25 tons
and are 19 years of age (vintage 2002). The RTUs currently meet the demands of the
system; however, the units are past their expected useful life (EUL) of 15 years as defined
by ASHRAE and are prone to fail in the near future. The RTUs are not equipped with
economizers which would otherwise provide free cooling opportunities when ambient
air conditions permit.

A roof-mounted 82% efficient atmospheric boiler generates heating hot water and circulates it to the reheat coils
located at the VAV boxes. While the existing boiler was rated to have an efficiency of 82% when manufactured,
due to wear and its exposure to the elements, its operating efficiency is now well below 80%.
Willdan’s investigation of the existing Reliable Controls BAS and the VAV box airflows showed that while the
actuators appear to be in good working condition, most of the air flow sensors at the VAV boxes are reporting
airflow values well below the actual amount being provided. Due to the incorrect airflow readings being reported
by the VAV air flow sensors to the BAS, the VAV boxes are providing more airflow than the systems need and the
corresponding VAV RTUs are operating their supply fans at speeds higher than they should be.

Energy Management Systems
The existing BAS is by Reliable Controls. The BAS shows graphical floor plans with zone temperatures, HVAC
equipment schematics, and provides the ability to schedule equipment hours of operation, most of which is
currently scheduled to operate from 5:00am to 10:00 pm. The BAS does not have any major functionality issues and
operates the system with a moderate degree of efficiency. There is room for some improvement on sequences;
however, the current system may limit the degree to which those improvements can be implemented. There are
some graphical issues related to Adobe Flash player not being supported by web browsers, but this does not affect
the operation of the equipment.

Corporation Yard & Maintenance Facility
General
The Corporation Yard is a single-story building located at 5709 Scarlett Court. The pre-
engineered metal building was constructed in 2015 and spans 21,859 square feet. The
City uses the space as maintenance grounds for its fleet of vehicles. The facility is open
weekdays 8:00am to 5:00pm.
Building Envelope
The building has an exterior construction of steel frame with metal siding, aluminum-
framed windows, and a gabled roof with metal finish. The material storage bins on the
South East end of the property have signs of wear and oxidation on their surfaces from
when it rains. However, it is unclear at this time if water is actually penetrating through
the material storage bins.
Electrical Systems
The main electrical service consists of a 208/120V, 3 phase, 4-wire MSB with a 1,200-amp
main bus, which is adequate for the facility. The Facility does not have any solar PV
installed to generate clean energy to offset building electricity use.
Lighting Systems
Lighting at the Corporation Yard consists of a mix of LED and fluorescent light fixtures. The
exterior of the building is all LED fixtures while the interior fixtures are a mix of LED (57),
linear fluorescent T8 (104), and CFL (4) fixtures. There are no occupancy-based lighting
controls to shut off lights when spaces are not in use.
Mechanical & HVAC Systems
The building has a variable refrigerant volume (VRV) system to supply conditioned air to
the spaces. The VRV system consists of ten Mitsubishi indoor fan coil units that are tied to
two Mitsubishi outdoor heat pump condensing units. VRV systems are very efficient as
they can provide simultaneous heating and cooling to different zones. There are
supplemental mini-split heat pump units serving electrical and server rooms. There are
eight exhaust fans operating for the shop and restrooms. Domestic hot water is
generated and supplied to the facility through an instantaneous electric water heater.
Energy Management Systems
The VRV systems are controlled by Mitsubishi thermostats that are designed to work with
the highly efficient indoor and outdoor VRV units to maintain indoor space comfort.
While the system is inherently efficient, there is no centralized BAS to provide remote
control resulting in extra steps for the maintenance team to adjust or review the system.
Connecting the VRV system to a BAS would allow remote space temperature setpoint
adjustments, scheduling, setback of the system, and review of system status.

Senior Center
General
The Senior Center is located at 7600 Amador Valley Blvd. The 15,207 square foot single-
story building was constructed in 2005 and has not had any major renovations since the
original date of construction. The facility offers a variety of classes and programs for the
community, along with a 248-person capacity ballroom and catering kitchen. When not
in use for City programs, the community can rent out the building. The facility is open
Monday through Friday 9:00am to 4:00pm and Saturday 8:30am to 12:00pm.
Building Envelope
The Senior Center has a conventional wood-framed structure on a concrete slab on
grade. The exterior walls have stucco finishes and aluminum framed windows. Most of
the roof has a gabled-type construction, while the equipment well has a flat construction
with a bituminous finish. Due to the building’s age, the roof should be either replaced or
patched and upgraded to support any future installations, such as an installation of solar
PV system array.
Electrical Systems
The main electrical service that powers all of the interior plug loads, lighting and HVAC
equipment consists of a 120/208V, 3 phase, 4-wire MSB with a 1,200-amp main bus and is
in the electrical closet, accessible through the exterior parking lot.
An existing 32-kW roof-mounted solar PV array offsets approximately 26% of the overall
site electrical usage. There is currently no BESS at the site to provide resiliency or
economic savings via peak shaving or energy arbitrage.
Lighting Systems
The Senior Center has a few LED light fixtures; however they are few and far between as
most of the facility contains a variety of older technology. The existing lights include a
combination of CFLs, metal halide lamps and linear fluorescent T8 tubes. Many areas do
not currently have occupancy sensors, which detect when the illuminated space is
occupied, and subsequently turn lights off when the space is not in use.
Mechanical & HVAC Systems
The Senior Center is conditioned by 12 individual packaged gas/electric RTUs. The units
are all 17 years of age (vintage 2004) except for one unit which was replaced 3 years
ago. The RTUs range in capacity from 2.5-tons to 7.5-tons of cooling. The 17-year-old units
are due for replacement as they are past their EUL as defined by ASHRAE. There are also
several Champion evaporative coolers located on the roof that supply cooled make-up
air to the kitchen. Domestic hot water is provided through a 116-gallon, 120MBH natural-
gas storage water heater.

Energy Management Systems
The rooftop HVAC equipment is controlled by occupancy-based Honeywell thermostats, all of which were noted to
be installed within lockboxes to prevent general access to the settings. Unfortunately, the lockboxes interfere with
the occupancy sensors, which renders them ineffectual, leaving the thermostats to rely solely on scheduled
programming for operation. The thermostats are not tied to a BAS to provide remote-control of the equipment.

Heritage Park & Museums
General
The Heritage Park & Museums site is a ten-acre park located at 6600 Donlon Way, and
is made up of the following buildings:
Murray Schoolhouse Museum (1856)
Old St. Raymond Church (1859)
Sunday School Barn (1870)
Hay Barn (1900)
Kolb Old House (1904)
Kolb House (1910)
The newest addition, Kolb House, is a 2,304 square foot, two-story facility. It is over a
century old (vintage 1910) and had MEP remodeling performed in 2010. The Museum
is open Monday through Thursday 3:00pm to 5:00pm.
Building Envelope
The various buildings are traditional wood-frame structures with wood framed
windows, siding, and minimal insulation.
Electrical Systems
Each of the buildings at the Heritage Park are individually metered, and have their
own 240V, 3-wire service that energizes the interior lighting, plug loads and HVAC
equipment. There are currently no solar PV systems used to offset electrical
consumption nor is there a BESS for resiliency or peak demand shaving. The Heritage
Park & Museums facility does not have an emergency backup generator to provide
power in the event of a power outage.
Lighting Systems
Lighting at the Heritage Park & Museums is a mix of metal halide (2), CFLs (48),
fluorescent T8 (11) fluorescent T5 (1), incandescent (2), and LED (49) fixtures. The
buildings do not contain occupancy sensors to reduce lighting levels when spaces
are vacant.
Mechanical & HVAC Systems
There is a mixture of old packaged gas/electric units, split heat pump units, and
ductless split systems found throughout the various buildings that are used to provide
heating and cooling. Standalone thermostats are used to control the HVAC
equipment to maintain temperature setpoints. The individual buildings have
independent HVAC infrastructure as follows:
Kolb House: two indoor Mitsubishi split system heat pump units (0.75 tons,
12 years of age) and two outdoor condenser units (1.5 and 5 tons, 12
years of age)

Shannon Community Center
General
The Shannon Community Center is located at 11600 Shannon Ave, and was
constructed in 2007. The facility is a two-story building spanning 17,286 square feet
and has had no major additions or renovations since the original construction. The
facility is used as a premier rental space for weddings, parties, and other events. The
Ambrose Hall, which is 6,000 square feet has the capacity to comfortably seat 300
guests. The facility is open Monday through Wednesday 8:00am to 5:00pm, Thursday
8:00am to 7:00pm, Friday 8:00am to 5:00pm, and Saturday 9:00am to 12:00pm.
Building Envelope
The exterior walls at Shannon Community Center are constructed of 2x6 studs,
sheathed with ½” plywood and has a stucco finish. The roof is a gable-type
construction with a concrete roof tile finish. The roof has R-30 insulation, the walls
have R-13 or R-19 insulation, and the windows are dual-pane.
Electrical Systems
The main electrical service consists of a 208/120V, 3 phase, 4-wire MSB with a 1,200-
amp main bus. There is a 116-kW-solar PV array located at Shannon Park that is
interconnected to the main electrical distribution panel. The system offsets
approximately 89% of the site’s electrical consumption. Given the high percentage
of solar PV offset, this site is not recommended to install more solar. The site was
originally partially configured for a back-up diesel generator, but it was never
installed.
The facility currently does not have a BESS to store solar energy. Willdan evaluated a
potential BESS for both economic return and resiliency at the facility, and does not
recommend energy storage at this time, as the economic return is not a high
enough value enough to offset the cost of the system over its lifetime. Extended
emergency backup power is more cost effective via a diesel generator
replacement, so no BESS is recommended for resiliency.
Lighting Systems
Lighting at Shannon Community Center consists of a mix of fixtures of LEDs (25),
fluorescent T8s (286), CFLs (236), and halogens (10). Most of the lights are controlled
by a Watt-stopper lighting control panel.
Mechanical & HVAC Systems
Heating and cooling to the entire building is provided by 15 Carrier split heat pump
units. The outdoor condensing units are floor-mounted along the northern perimeter
of the community center. The cooling capacities for these units range from three to
five tons and have a 15 SEER rating. The indoor furnace units have a gas-fired
heating section, evaporator cooling coil and blower motor to circulate the air to
the spaces. The split systems are all controlled by stand-alone thermostats and
operate to maintain their temperature setpoints. There are two kitchen exhaust fans

and one make-up air unit that are interlocked with the kitchen range hood to provide ventilation and maintain
space pressurization. All fans are constant volume. Domestic hot water is generated by a gas-fired, condensing
storage water heater.

Energy Management Systems
The Shannon Community Center has stand-alone thermostat controls to control the HVAC equipment. The
thermostats are tied to a Niagara framework DDC based Alerton control system to provide remote-control of the
equipment. The existing BAS was designed to be able to work in tandem with the proposed PV systems to provide
resiliency during emergency scenarios with minimal load shedding.

Fire Station #16
General
Fire Station #16 is located at 7494 Donohue Dr. and was constructed in 1992. The
facility is a two-story building spanning 8,815 square feet and had a minor remodel in
2006. The building is open 24/7, year-round.
Building Envelope
The structure is composed of masonry bearing walls with wood framed, built-up
roofs. Due to the age of the building, re-roofing may be necessary before installing
additional solar panels.
Electrical Systems
The main electrical service consists of a 208/120V, 3 phase, 4-wire MSB with a 600-
amp main bus. There is a 12-kW-solar PV array that was installed in 2012 located on
the roof that is interconnected to the MSB and offsets approximately 24% of the site’s
electrical consumption. While additional utility bill offset from solar PV would be ideal
at this facility, significant constraints on available roof and parking lot space leads
Willdan to not recommend installing supplemental rooftop solar PV or carport
mounted systems at this time. When the existing solar PV reaches the end of its useful
life around 2032 or in the event that system performance degrades significantly, the
system should be updated to current technology which will offset a greater
percentage of the facility load.
The facility currently does not have a BESS, only an aging 80kW diesel generator
located outdoors, original to the facility’s construction, exists to provide back-up
power during power outages. Willdan evaluated a potential BESS for both economic
return and resiliency at the facility and does not recommend energy storage at this
time, as the economic return is not a high enough value to offset the cost of the
system over its lifetime. Extended emergency backup power is more cost effective
via a diesel generator replacement, so no BESS is recommended for resiliency.
Lighting Systems
Lighting at the Fire Station #16 primarily consists of fixtures of CFLs (42) and T8
fluorescents (83). Interior LEDs fixtures (33) were found primarily on the wall sconce
fixtures and exterior pole fixtures. There are also high-pressure sodium (4), mercury
vapor (5) and metal halide (2) fixtures. Many areas do not have existing lighting
controls.
Mechanical & HVAC Systems
Heating and cooling to the fire station is provided by four packaged Carrier rooftop
gas/electric units and one heat pump that are controlled by stand-alone
thermostats and range in size from 2 to 6 tons. All of the units are 15 years of age. The
fire truck apparatus bay has several natural gas-fired unit heaters and two
apparatus exhaust fans serving the north and south areas. Domestic hot water is

Fire Station #17
General
Fire Station #17 is located at 6200 Madigan Rd. and was constructed in 2002. The
facility is a single-story building spanning 12,727 square feet and has had no major
renovations. The building is open 24/7.
Building Envelope
The structure is composed of a steel framed structure, with exterior CMU walls and
interior gypsum board. The roof has a hip-style framing with a metal finish. Due to the
age of the building re-roofing the building may be necessary before installing
additional solar panels.
Electrical Systems
The main electrical service consists of a 208/120V, 3 phase, 4-wire main switchboard
distribution system to sub-panels. There is an existing 38-kW solar PV carport array that
was installed in 2012 located in the parking lot that is interconnected to the MSB. The
system offsets approximately 56% of the site’s electrical consumption and there is an
aging 150kW diesel generator, original to the facility’s construction, located outdoors
to provide back-up power during power outages.
Lighting Systems
Lighting at the Fire Station #17 consists primarily of CFLs (42) and T8 fluorescents (161)
fixtures. Interior LED fixtures (23) were found primarily on the wall sconce fixtures and
exterior pole fixtures. There are also incandescent (9) and metal halide (2) fixtures.
Many areas do not have existing lighting occupancy-based controls.
Mechanical & HVAC Systems
There are four split-system, forced-air furnaces housed within the mechanical room
that supply heating and cooling to the occupied areas of the fire station. The
outdoor condensers indicate the units are 17 years of age (vintage 2003). There is an
exhaust fan with a variable frequency drive in the same mechanical room that is
used to extract the fumes out of the fire truck apparatus bay to the outdoors. The
apparatus bay has several natural gas-fired unit heaters. There is a two-ton, wall-
mounted split-system heat pump unit serving an IT closet. There are two 50-gallon,
gas-fired, storage water heaters installed in 2019 that generate potable, domestic
hot water.

Fire Station #18 is located at 4800 Fallon Rd. and was constructed in 2003. The facility
is a single-story building spanning 8,624 square feet and has had no major
renovations. The building is open 24/7.
Building Envelope
The building is composed of a steel framed structure, with a mixture of exterior CMU
walls and stucco finishing. The interior finishes consist of CMU in the apparatus bay
area, and gypsum board in all other occupiable areas. The roof has a hip-style
framing with a metal finish.
Electrical Systems
The main electrical service consists of a 208/120V, 3 phase, 4-wire main switchboard
distribution system to sub-panels. There is a 26-kW solar PV carport array located in
the south-western parking lot that is interconnected to the MSB. The system offsets
approximately 61% of the sites electrical consumption. There is a 123.5kW diesel
engine generator that is used as back-up during power outages.
Lighting Systems
Lighting at the Fire Station #18 consists primarily of CFL (34) and T8 fluorescent (119)

The Wave at Emerald Glen Park
General
The Wave Aquatic Center is located at 4201 Central Pkwy and was constructed in
2017. The facility consists of a Natatorium, Waterpark and Community Room. The
Natatorium houses the indoor pool for a year-round swim school, lap swimming and
water fitness programs. The Waterpark features multiple water slides and the Splash
Zone for children. There is an 11-lane outdoor sports pool that can host competition
swim meets and related events. The Community room has an auditorium that can
seat upwards of 215 people and is used for a variety of meetings and special
events.
Electrical Systems
The main electrical service consists of a 277/480V, 3 phase, 4-wire MSB with a 2,000-
amp service. There is not currently a solar PV system installed nor battery energy
storage system at the site to provide on-site generation, resiliency or economic
savings via peak shaving or energy arbitrage. There is a small battery backup to
support emergency lighting in case of a power outage. However, these battery
systems have a relatively short life, and they are prone to failure if not maintained
and tested regularly.
Lighting Systems
Much of the Interior and exterior lighting at the Wave Aquatic Center is LED and
controlled by a Watt-stopper lighting control system. However, some 28W
fluorescent tubes are installed in the building interior, CFLs illuminate the restrooms,
and halogen luminaires are installed in the natatorium. While this is a relatively new
building, fluorescent fixtures are still often used in new construction.
Mechanical & HVAC Systems
There is a 42-ton variable air volume air-conditioning unit that supplies conditioned
air to the main building via VAV terminal units with reheat coils for zone temperature
control. There is a VAV indirect evaporative cooler (IDEC) with heat recovery
serving the Natatorium that is used for dehumidification. Two heating hot water
centralized boilers are piped in parallel through a common header and are used to
supply heating hot water to the VAV reheat coils and the indirect evaporative
cooler.
The pool equipment room houses two 130-gallon, gas-fired, condensing, storage
water heaters and one 120-gallon, electric, storage water heater that generate
domestic hot water and circulate it via three hot water pumps. There are four gas-
fired Lochinvar Aquas packaged water heaters: (1) indoor swimming pool (ISP)
heater, (1) outdoor swimming pool (OSP) heater, (1) Activity Pool (AP) Heater, (1)
Slide (SL) Pool heater. All pools have their set of circulation pumps and filter units.
Only the OSP and AP have a set of booster pumps. The ISP, OSP and AP circulation
pumps have VFD controls. The ISP also has multiple thermal solar collector arrays
mounted on the building roof to assist in heating the AP.

Parks & Sports Field Lighting
Dublin Sports Grounds
The Dublin Sports Grounds consists of Baseball, Soccer, and Sports Grounds Fields. The fields are lit by one-
hundred-fifty-eight 1500W fixtures. Dublin Sports Grounds is located adjacent to the Civic Center which has an
existing solar PV system, so their electrical services are candidates for benefitting meters in a Net Energy Metering
Aggregation scenario, where bill credit is transferred from the adjacent site’s solar generation to the park’s
electrical meter. It has been noted that there are some branch circuit shorts related to some of the lighting and
has been accounted for in our recommendations.
Emerald Glen Park
Emerald Glen Park has a skate park, tennis courts, and basketball courts which are lit by forty-two 1000W fixtures.
Emerald Glen Park is located adjacent to The Wave which may feature a solar PV system in the future, so their
electrical services are candidates for benefitting meters in a Net Energy Metering Aggregation scenario, where
bill credit is transferred from the adjacent site’s solar generation to the park’s electrical meter.
Fallon Sports Park
Fallon Sports Park has softball, soccer, and baseball fields, as well as tennis and basketball courts. The fields and
courts are lit by two-hundred and fifty-nine 1500W fixtures. Fallon Sports Park has a large enough annual electrical
load and space for its own net-metered solar PV system. See the Improvement Measures section of this report for
more specific information on recommendations.
Kolb Park
Kolb Park has tennis courts which are lit by sixteen 1000W fixtures.

| Investment Grade Engineering Audit | Page 30
Traffic Signals
The City primarily has Alpha battery backup systems (BBS) at the intersections with the exception of only a few
Myers and Tesco systems. However, it is important to note that many of the existing systems are of a line-interactive
BBS type which do not have the same advantages as more advanced online double conversion BBS types.
Additionally, four of the City’s key intersections do not yet have a battery backup system in place.
Willdan performed site visits to the 22 existing signalized intersections on January 11 and 12, 2021, to conduct field
inventories of existing traffic signal equipment and controller cabinets. The traffic signal at Horizon Parkway and
Scarlett Drive has not been constructed, so no field inventory was performed for this location.
Willdan noted whether an existing battery backup system was present and measured the maximum electrical
current draw at each controller cabinet to determine the existing power demands for the traffic signal system.
The measurements were done by observing what the highest current draw for the signal system during a
complete cycle of the signal phasing. The table below shows the results of the electrical current measurements
and whether the existing controller cabinet had a battery backup system.

Streetlights
Many of the City’s streetlights have already been converted to LED with the exception of a few clusters and
Dublin’s Special District referred to as Dublin Ranch, located on the east side of the City. Although some LED
streetlights exist on the main streets within Dublin Ranch, many neighborhoods still feature decorative type fixtures
featuring metal halide and sodium vapor lamps. These lamps range from 36Watts to 131Watts each and do not
feature any controls. The following figure, although not inclusive of the entire Dublin Ranch District, provides a visual
representation of the existing streetlights within the area and their lamp types.
The streetlights within Dublin Ranch District are on PG&E’s LS-2A tariff. Under this tariff, the streetlights are owned and
maintained by the City while PG&E supplies energy and service only. As these streetlights are not metered, PG&E
bills for their use of electricity at a fixed monthly cost based on the existing lamp type and rated wattage,
regardless of how much electricity the fixtures may actually be using. Due to this tariff’s arrangement, if streetlights
are upgraded to a lower wattage lamp such as LED but are not reported back to PG&E for updates to their billing,
customers will continue to be billed at the same rate even if less electricity is now being used after the fixture
upgrades. It is unclear whether this may be occurring for billing of the Dublin Ranch District streetlights at this time,
however, discrepancies appear to exist between PG&Es city-wide lighting inventory and the City of Dublin’s.

Energy Savings Analysis Methodology
In order to evaluate how the City of Dublin facilities use energy, formulate specific opportunities for
energy conservation and accurately calculate energy savings, Willdan’s engineers performed a
detailed analysis process that encompasses:
Investigating facilities to gain a deep understanding of the energy consuming systems’
operation and efficiency.
Utilizing a combination of mathematically accurate bin calculations and detailed lighting
and water consumption analysis to calculate energy savings in terms of kilowatt hours
(kWh), kilowatts (kW), and Therms (Th).
Building a detailed simulation of each facility’s utility tariff to obtain an accurate annual
dollar savings
Performing a comprehensive financial analysis of each conservation measure being
considered to provide owner/decision makers with the data needed to make informed
decisions.
Savings During Construction
One or more ECMs in this project are expected to be operational and delivering savings long before the end of the
implementation period. Capturing the savings that accumulate during the construction phase will have a positive
impact on the overall project economics by possibly reducing the amount to be financed and the associated
interest expense.

Project Contribution Toward CAP 2030
Willdan's proposed wholistic approach to DERs at the City of Dublin addresses numerous measures laid out in the
City's CAP 2030. Projects in this comprehensive package will help pave the way for future renewable and
resiliency goals at the City and within the Dublin community at large. This project’s contribution toward the City’s
CAP 2030 are discussed below.
ML-1: All of the different aspects of Willdan's comprehensive DER project are supportive of CAP
Measure ML-1. In the six listed actions for ML-1, the first is already complete with the City's successful
transition to EBCE's 100% Renewable electricity rates as part of CAP Measure CF-1. Actions 2-6 are all
addressed by the comprehensive DER project, including staff engagement at critical facilities to
evaluate DERs for resiliency, a pilot program for solar & battery storage at multiple locations, policy to
identify parameters for installation of solar & storage, education and training on battery storage to
relevant City staff, and annual reviews of solar production and cost savings from DERs. The CAP
identifies the GHG reduction potential for this measure as 205 MT CO2e (metric tons of carbon dioxide
equivalent) by 2025 and 156 MT CO2e by 2030.
CF-2: As part of the CAP's Strategy 1, measure CF-2 sets goals to develop a Renewable Resource
Buildout Plan, in which the City will develop local solar PV resources and identify opportunities for and
implementation of microgrids that will increase the resilience of facilities that provide shelter and value
to the community. Willdan's project addresses this directly, with new solar PV installations at 8 City
facilities, battery storage at four sites, and a resilient microgrid at The Wave waterpark. While the CAP
deems that there are no direct GHG emissions from this measure due to the City's successful transition
to EBCE's 100% Renewable electricity rates in CAP Measure CF-1, these measures demonstrate an
alternative pathway which Dublin can pursue to remain on 100% renewable electricity while
generating additional cost savings to the City, promote renewable resource adoption in the
community, and pave the way for future renewable installation and resiliency efforts in the local
community.
EE-3: Installing multiple BESS as part of the comprehensive project will support the CAP Measure EE-3,
which lays out goals to streamline the battery storage permit process within the City and to provide
education and outreach to the community on the benefits of battery storage and availability of
renewable power. The facilities which will receive BESS can function as a living laboratory for both City
staff and community members.
SM-1: Willdan's proposed project scope at the Dublin Sports Grounds (DSG)/Civic Center/Library
complex is supportive of CAP Measure SM-1, which lays out the goal to adopt an electric vehicle
charging station ordinance to increase access to charging stations and promote the use of electric
vehicles. Key ordinance metrics outlined in the measure require 25% of parking spaces at commercial
buildings to be "EV Ready" (conduit and electric panel capacity installed), with 3% of parking required
to have installed and operable Level 2 charging stations. The proposed Solar PV + EV Charger scope
located in the DSG parking lot and serving the entire Civic Center/Library complex achieves those
target ordinance metrics.
ML-3: CAP Measure ML-3 states that the City's municipal government will electrify at least 33% of its
municipal vehicle fleet and maintenance equipment by 2030. Proposed measures for EV charging
stations and "EV Ready" infrastructure at the Public Safety Complex and Dublin Sports Grounds/Civic
Center complex support this measure by providing the critical planning and electrical infrastructure to
serve the vehicle fleet as it heads towards the 2030 goal.
406
| Investment Grade Engineering Audit | Page 45
EV Charger GHG Emissions: EV Chargers installed as part of this project for Dublin’s light duty fleet will
enable the full transition of Dublin’s fleet to EVs by 2030. GHG emission reductions attributed to this
conversion from EBCE’s Municipal Fleet Electrification, Charging Infrastructure, and DER Assessment is
roughly 49 MT of CO2 from 2020 baseline.
EV Chargers installed at the Dublin Sports Grounds will strongly promote EV adoption throughout Dublin.
Willdan, with input from the EBCE report, estimated that the 30 initial EV chargers at DSG will dispense
roughly 321,000 kWh/year in electricity. Assuming electric vehicles have an average efficiency of
40kWh/100 miles driven, this equates to a yearly reduction of 321 MT of CO2e. Additional GHG
reductions are also possible through the influence and convenience of a public charging station in
Dublin. Residents who switch from an internal combustion engine vehicle to an electric vehicle will
reduce further CO2e for every mile they drive. For every 100 vehicles purchased that drive an average
of 15,000 mi/year, this will equate to another reduction of 600 MT of CO2e.

Facility Resiliency and CAP Goals
As Dublin looks to reach carbon neutrality by 2045, in alignment with its Climate Action Plan, Willdan's
recommendation to install new diesel generators may seem at odds with meeting this goal. In our
analysis of different resiliency options, dictated by Dublin's Emergency Operations Plan and in response
to increasing Public Safety Power Shutoffs, Willdan considered the installation of Battery Energy Storage
Systems (BESS) to provide sustained facility operation during a grid outage. However, given current
Solar PV, BESS and Microgrid pricing, a zero-emission resiliency solution proved to be prohibitively
expensive at this time. To meet the urgent need for multi-day PSPS resiliency, Willdan still recommends
diesel generators for extended facility backup.
The installation of new diesel generators at this point, however, do not preclude Dublin from reaching
its carbon neutrality goals. First off, diesel generators are only run during power outages (and a minor
amount of regular testing) and therefore contribute very little to the overall emissions of the City. Next,
the life of a diesel generator is typically 20-25 years, and even generators installed in 2021 will be up for
replacement between 2041-2046, so they will be due for replacement again just in time for the 2045
carbon neutrality goals. At that time, battery technology and pricing will be better suited and more
economically feasible to provide the extended backup required by PSPS.
Lastly, in parallel to the further refinement of battery technology, carbon intensity of diesel fuel
continues to improve. Biodiesel, a liquid fuel produced from renewable sources, such as new and used
vegetable oils and animal fats has been around for quite a while and provides a cleaner-burning
diesel than petroleum-based diesel fuel. Due to its chemical properties, it is meant to be blended with
petroleum-based diesel increasing its carbon intensity. However, straight use of B100 (100% biodiesel)
can be harmful to long term engine operation. Consequently, many internal combustion engine
manufacturers do not warranty their products if a concentration biodiesel above a certain threshold
(typically >10%) is burned. For this reason, biodiesel is not recommended for use in the generators.
A newer "non-petroleum" diesel alternative is renewable diesel, which is a biomass derived
transportation fuel. Chemically similar to standard petroleum-based diesel fuel, this fuel shows
significant potential to decarbonize sources that will continue to rely on diesel well into the future. The
problem with renewable diesel in 2021 is supply. As of 2018, there were only four plants in the US that
produce this fuel, and a large majority of it is consumed in California by large transportation logistics
carriers because Low Carbon Fuel Standard (LCFS) Credits make it affordable and they can buy in
significant bulk. While this may not be a viable option for the City of Dublin today, the fuel is on the
cusp of becoming more widely available, and Dublin should continue to track its availability in the
coming years.

Electrification Evaluation of Facility HVAC Systems
As part of the IGA, Willdan evaluated the option to electrify HVAC systems along with the option to replace
existing gas/electric units with new more efficient gas/electric units (like in kind) in support of the City of Dublin’s
CAP. Upon analysis, electrification of the existing HVAC systems poses a number of challenges. These challenges
are described in the following paragraphs and ultimately result in Willdan’s recommendation to replace existing
gas/electric HVAC units with more efficient like in kind units at this time. As HVAC systems typically have an EUL of
15 – 20 years, there will be another opportunity in the future to revisit electrification of HVAC systems to support
the City’s 2045 carbon neutrality goals. At that time, Willdan recommends that the HVAC systems for each facility
be evaluated for a comprehensive re-design to take advantage of newer technologies such as variable-
refrigerant-flow (VRF), rather than be evaluated for electrification on a unitary basis. HVAC technology and
pricing is expected to be better suited and more economically feasible in the coming years.
For evaluating the electrification option of HVAC systems, Willdan used the following information as the basis of
design: The City of Dublin is located in CA Climate Zone 12. ASHRAE Fundamentals 2017 Handbook specifies
Livermore as being the closest location to the City of Dublin with a dataset available for HVAC design conditions.
The design criteria provide the following:
Heating dry-bulb temperature of 30.2 F (99.6%)
Cooling design of 99 F dry-bulb and 67.8 F wet-bulb.
2,773 Heating Degree Days
796 Cooling Degree Days
Record low temperature within the area of 18 F and record high of 115F
One option for electrification of unitary HVAC systems is to install heat pumps. However, the main issue that arises
when evaluating this option is that due to the heating loads for the facilities in the City of Dublin, the heat pumps
will need to be sized for the heat load as opposed to the cooling load as traditionally performed. As heat pumps
share the same compressor(s) and internal components for both heating and cooling purposes, this causes the
units to be sized larger than the existing gas/electric units by as much as 30% in terms of their available cooling
capacity or tons of cooling. For example. an existing 5 ton gas/electric packaged unit may need to be replaced
with a 7.5 ton gas/electric package unit. The increase in unit size brings about challenges such as increased M&L
cost to install due to the following:
Packaged rooftop units will likely require a roof curb-adapter
Increased electrical service
Code required economizer and controls upgrade needed
Clearance issues around existing location
Resizing and or rebalancing of ductwork
Structural evaluation due to increased weight
Oversizing of the units brings about concerns when cooling loads are relatively low as this will lead to the
conditioned spaces reaching their space temperature set point more quickly, causing the unit’s compressors to
cycle on and off more frequently. This causes additional wear on the compressor which may result in accelerated
compressor failures that can prove costly. The increased use of the compressor for heating will also warrant for
routine maintenance to be performed more regularly contributing to increased O&M costs. Additionally, the
409
| Investment Grade Engineering Audit | Page 48
energy efficiency performance of the units is also impacted. These concerns however, may be alleviated by
selecting advanced HVAC units featuring multiple compressors or variable speed compressors.
Heating from a heat pump suffers from loss of heating capacity and poorer performance as outdoor air
temperatures drop below 40 F. This condition is due to the heat pump becoming limited to the amount of usable
heat that it is able to extract from the outdoor air. The very low heating supply air temperature which results from
this raises concerns about the unit’s ability to have a timely impact on the changing heating load in the building
and has a negative impact on the unit’s energy efficiency. To overcome this loss of heating functionality at lower
temperatures, manufacturers employ an electric resistance heating coil to preheat the incoming outdoor air or
cold return air from the building to a point where the heat pump can effectively provide heating.
An item to note for future electrification considerations is that electrification of HVAC systems may not necessarily
result in significant increases to annual utility costs. Heating occurs primarily during winter months and during
mornings when utility rates are typically off-peak and therefore at their lowest. Furthermore, Solar PV may be used
to further drive down the additional costs associated with using electricity for heating.

Baseline Utility Analysis
The table below shows the baseline data calculated for each building. This data was used to calculate expected
savings of the included recommendations. The baseline data calculation methodology is described below.
T ABLE 15. B ASELINE U TILITY A NALYSIS
* Natural gas consumption data was not available during the period this analysis was performed.
The baseline energy consumption evaluation was developed with a building-specific utility analysis. This analysis
used actual reported utility consumption as defined by monthly utility bills. The utility bills used for this analysis were
from January of 2018 to January of 2020. The data from the utility bills was normalized to typical local weather
conditions using TMY3 (Typical Meteorological Year, version 3) data. TMY3 contains a full year of hourly weather
data (8,760 hours), where each hour is chosen as an average over 15 years, in order to represent the most median
conditions for the local area. A linear regression analysis was performed to generate the relationship between
energy use and actual degree-days. A typical year’s degree-days are then applied into this correlation to obtain a
12-month utility baseline. In the case of natural gas, only heating degree-days were used because it assumed that
temperature-dependent consumption of gas only applies to the heating months. Cooling degree-days were used
to correlate electrical demand (kW) and consumption (kWh) for space cooling. The baseline data is used for both
bin analyses and to calibrate computer simulation building models. This analysis is conservative in that it establishes
median conditions based on historical data and therefore does not attempt to account for future weather
conditions.
The baseline for all lighting consumption and demand was generated through a comprehensive lighting audit
performed to document all fixtures, lighting controls, circuiting, and operation. Each fixture in every building was
analyzed to determine the following: existing wattage, lumen output, ballast factor, and rated run hours. Tables

determine total lighting load, consumption, and cost are also available in the appendix.

Civic Center
Install Solar PV and Battery Energy Storage
Willdan recommends installing a
new carport solar PV system in the
reconfigured lot with a capacity of
approximately 232 kW (DC) and a
32kW/64kWh BESS.
Since the Civic Center is under
development at this time for the
construction of a Cultural Arts
Center, Willdan took a conservative
approach to sizing solar PV and
BESS at this site and also is
recommending a project which leverages the parallel renovation of the former Police facility to a Cultural Arts
Center.
Our analysis considers that the load from the Civic Center Complex will remain the same and only recommends
installing additional solar PV to offset future load growth from additional building load and fleet electrification.
The existing 370-kW solar PV system offsets approximately 48% of the site’s load. Taking the future load growth,
undersized existing solar PV relative to the current annual site loads, and availability of space in the reconfigured
lot, Willdan proposes to furnish and install a new 232 kW (DC) net-metered photovoltaic (PV) system that will be
mounted as a carport system in the reconfigured lot. The carport will have a tilt angle of 7 degrees above
horizontal facing southwest. The system will include Boviet 445W Tier 1, CEC-listed modules with a 12-year
warranty and a 25-year linear power output warranty, and Chint 50kW inverters with a 10-year warranty.
This system size will allow the site to fully realize electricity bill savings from the building site loads and future
planned EV fleet charging loads, and excess generation can also be credited to the adjacent Dublin Sports
Grounds electric bills via the Net Energy Metering Aggregation tariff. Solar PV also supports Dublin’s Climate
Action Plan to increase renewable energy around the City (CF-1) and the proliferation of EV charging in support
of Dublin’s Charging Station Implementation Plan (SM-2). Additional solar PV will also provide the foundation for
future zero emission resiliency projects throughout the City.
As the site currently lacks a BESS, there is no way to store collected solar energy from the existing PV system for use
during peak hours. Willdan has evaluated different BESS options, for resiliency and for economic benefit and
concluded that the most beneficial BESS application is a 32kW/64kWh BESS that could be interconnected at the
same time as the proposed solar PV system, which would provide electricity bill savings by reducing peak
demand charges. The BESS manufacturer will be EnerGPort and the system will have a 10-year warranty. Since
the site has an adequately sized existing diesel generator, the BESS will not be utilized in an emergency for
backup power.

Dublin Library
Replace HVAC Systems with High Efficiency Equipment
This project recommends replacing the roof-mounted gas boiler with a new gas-fired, high efficiency condensing
boiler, along with the expansion tank, circulation pump and local temperature sensors, pressure gauges, valves,
insulation, and any piping deemed not re-usable. The new condensing boiler will have a minimum rated
efficiency of 95% with a turndown ratio to further enhance efficiency during part-load operation. The new
condensing boiler will be of similar heating capacity as the existing boiler and will be located at the same
location as the existing boiler for ease of installation to the existing electrical, plumbing, and controls systems.
All five of the RTUs, ACU-1 thru ACU-5, are to be replaced with new RTUs featuring an IEER that exceeds CA Title-
24 requirements. The new units will be equipped with economizers to provide free cooling when ambient
conditions permit and barometric relief dampers to assist with maintaining building pressure. The new units will
also come standard with fault detection and diagnostics capabilities to provide notifications to the
corresponding thermostats should an issue occur with the operation of the economizers. The new units will be
installed in the same location as the existing units; however as the new RTUs feature a different footprint than the
existing ones, roof curb adapters will be installed as needed to accommodate their installation. Ductwork,
electrical, and condensate systems may be extended or slightly modified as well to accommodate the
installation of the new units. As the existing condensate lines are terminated at the roof stormwater drains,
rerouting of the condensate lines for proper termination into the nearest code compliant receptacle may be
required.

Install New Wireless, Internet Based Controls
The Dublin Library has a Reliable Controls system and while the building automation system has no inherent or
functional issues, it’s energy saving control strategies, ease of accessibility, and reporting can be improved upon.
Additionally, there is an opportunity to standardize the controls systems across the City’s facilities and expand
throughout the City where DDC controls currently do not exist.
417
| Investment Grade Engineering Audit | Page 56
This project recommends installing Pelican Wireless controls to further reduce energy consumption and costs, as
well as ease the time burden associated with maintaining individual thermostat settings throughout the City of
Dublin’s facilities. The Pelican Wireless thermostats would be connected to a single, web-accessible graphical
user interface (GUI) to allow for centralized schedule management, reporting, and troubleshooting of all major
heating and cooling equipment throughout the City’s buildings. This system would allow individual zones to have
different occupied or unoccupied temperature schedules, as well as alert the building operators to errors and
routine maintenance.
Additional benefits of the Pelican system include:
1. The Pelican system does not use or rely on the building’s internal Wi-Fi or LAN networks for thermostat
communication. The Pelican gateway broadcasts its own wireless backbone, establishing a mesh network
that only talks to other Pelican devices, some of which act as repeaters themselves. This allows for minimal
interference to existing networks, while still allowing for remote access through City staff web-enabled
devices.
2. The thermostat configuration (temperature setpoints) and schedules are stored locally at the thermostats.
Should the building lose internet connectivity, the Pelican system would continue to function by following
the schedules and setpoints stored locally.
3. Carbon dioxide (CO2) sensors built into thermostats for monitoring of CO2 concentrations within spaces.
This project includes the installation of the following devices which would enable control over VAV box damper
actuators, economizer dampers, heating hot water loop temperature setpoints, and thermostats. Equipment
includes:
(1) Z24 Zone Controller for ACU-1
(4) Z8 Zone Controller for ACU-2,3,4,5

Install Solar PV
The Library’s parking lot is filled out with an
existing 132-kW carport array that offsets
approximately 36% of the building’s load.
With no remaining carport space available,
Willdan has evaluated the rooftop
conditions and orientation and proposes to
install a rooftop solar PV system with a
capacity of approximately 128 kW (DC).
The system mounting will be a combination
of ballasted on the flat roof areas and flush-
mounted to the standing seam pitched
metal roof areas, both with a tilt angle of 10
degrees above horizontal. The system will
include Boviet 445W Tier 1, CEC-listed
modules with a 12-year warranty and a 25-
year linear power output warranty, and
Chint 50kW inverters with a 10-year warranty.
This system size will allow for maximum electricity bill savings by offsetting the full annual site load of the building in
conjunction with the existing system. Solar PV also supports Dublin’s Climate Action Plan to increase renewable
energy around the City (CF-1). Additional solar PV will also provide the foundation for future zero emission
resiliency projects throughout the City.
As the site does not have a BESS, there is currently no way to store collected solar energy from the existing PV
system for use during peak hours. Willdan evaluated a potential BESS at the site for both economic return and
resiliency purposes. Based on modeling results, it is not recommended to install BESS for economic return, as the
system will not deliver benefit equal to or beyond the installation cost. Additionally, emergency backup power is
more cost effective via a diesel generator, so no BESS is recommended for resiliency. Please refer to the next
section for more details on this project.
Install a Standby Generator
A new 300kW generator will be installed on the west side of the Library. This generator will provide standby
electrical power to the Library in case utility power is interrupted. To integrate this generator into the Library’s
electrical system, a new automatic transfer switch will be installed. This transfer switch detects utility power
interruption, then initiates a generator startup. Additionally, the transfer switch isolates the building from the utility
grid, preventing any “back feed” of power onto the utility grid. This function is required by the National Electrical
Code, and it is important to the safety of utility technicians. There will also be the option to use renewable diesel,
when available, to reduce emissions. As the Library serves as a shelter for employees and children during an
emergency, as outlined in the City’s Emergency Operations Plan, installing a reliable source of power is crucial.
Upgrade Interior/Exterior Lighting to LED
The intent of the project is to replace all fluorescent, incandescent, and HID lighting with LED lamps or new fixtures
to reduce energy use and maintenance costs. LEDs last 2-4 times longer than fluorescent lamps and can be
installed without ballasts to avoid another point of failure which may occur at light fixtures. As part of this scope
419
| Investment Grade Engineering Audit | Page 58
of work, dirtied lenses will be cleaned before installation of replacement lamps, and any damaged ceiling tiles
will be replaced. Additionally, occupancy-based and daylighting controls will be installed. Occupancy sensors
detect when the illuminated space is occupied, and subsequently turn lights off when the space is not in use. The
Library contains areas that are well-lit by daylight outside the building during the day. In these areas, this project
proposes to install daylight harvesting controls. These controls adjust lights to maintain the space’s target lighting
levels when adequate illumination through the building’s glazing is detected in the space. Detailed information
about the recommended replacement can be found in the section titled “Appendix B – Lighting”.

Corporation Yard & Maintenance Facility
Install Solar PV and Battery Energy Storage
To provide economic benefit and 8 hr. resiliency
at Dublin’s Corporation Yard, Willdan proposes to
furnish and install an approximately 47 kW (DC)
flush-mounted rooftop PV system with a tilt angle
of 12 degrees above horizontal. The system will
include Boviet 445W Tier 1, CEC-listed modules
with a 12-year warranty and a 25-year linear
power output warranty, and Delta 42kW inverters
with a 5-year warranty. The Solar PV also supports
Dublin’s Climate Action Plan to increase
renewable energy around the City (CF-1). Solar
PV at the site will generate additional electricity to
increase Dublin’s bill savings at this facility and
provide the foundation for future zero emission
resiliency projects throughout the City.
During normal operations the solar PV will offset the electrical load at the Corporation Yard. The Corporation
Yard is slated to serve as the Field Communications Center according to Dublin’s Emergency Operation Plan, so
resiliency is important here. To that end, Willdan is recommending an EnerGPort BESS of 100kW/165kWh with a 10-
year warranty, which will be reserved for resiliency purposes. A battery of that size should be able to carry the
entire Corporation Yard for ~8 hours, longer if only critical loads are supported or recharged from the roof-
mounted Solar PV.
Upgrade Interior/Exterior Lighting to LED
The intent of the project is to retrofit all linear fluorescent T8 lamps with LED tube replacements to reduce energy
use and maintenance costs. Similarly, CFL fixtures will be replaced with LED lamps with equivalent lumens. LED
fixtures last 2-4 times longer than fluorescent lamps and can be installed without ballasts to avoid another point of
failure which may occur at light fixtures. Additionally, occupancy sensor controls will be installed. Occupancy
sensors detect when the illuminated space is occupied, and subsequently turn lights off when the space is not in
use. Detailed information about the recommended replacement can be found in the section titled “Appendix B

packaged York RTU air conditioners with gas heating. The 12th unit, AC-3, was replaced in 2018 and is therefore
excluded from this scope. The new RTUs shall have an IEER or SEER that exceeds CA Title-24 efficiency
requirements. The new units will be installed in the same location as the existing units, however as the new RTUs
feature a different footprint than the existing, roof curb adapters will be installed as needed to accommodate
their installation. Ductwork, electrical, and condensate systems may be extended or slightly modified as well to

proposes to furnish and install an
additional 38kW (DC) roof flush
mounted solar PV system with a tilt
angle of 18 degrees to generate

that Dublin sees from Solar PV at the
site. The system will include Boviet

Heritage Park & Museums
Replace HVAC Systems with High Efficiency Equipment
The HVAC equipment systems throughout the museum and parks vary from packaged gas/electric equipment to
unitary split systems and range in capacity from 1.5-tons to 5-tons. This project recommends replacing only AC-2
at the Museum given its condition and age of 22 years which is beyond its EUL according to ASHRAE. The
replacement unit will be a like in kind, high efficiency unit featuring a SEER that exceeds CA Title-24 requirements.
The new unit will be equipped with an economizer to provide free cooling when ambient conditions permit and a
barometric relief damper to assist with maintaining building pressure. The new unit will also come standard with
fault detection and diagnostics capabilities to provide notifications to the corresponding thermostat should an
issue occur with the operation of the economizer. The new unit will be mounted on the existing concrete floor
pad and shall reconnect to the existing ductwork distribution. However, ductwork, electrical, natural gas, and
condensate systems may be modified to accommodate the installation of the new unit. The existing ductwork
within the building shall remain the same. As the existing condensate line is terminated over the soil near the unit,
rerouting of the condensate line and installation of a dry well for proper termination may be required.

1. The Pelican system does not use or rely on the building’s internal Wi-Fi or LAN networks for thermostat
communication. The Pelican gateway broadcasts its own wireless backbone, establishing a mesh network
that only talks to other Pelican devices, some of which act as repeaters themselves. This allows for minimal
interference to existing networks, while still allowing for remote access through City staff web-enabled
devices.

2. The thermostat configuration (temperature setpoints) and schedules are stored locally at the thermostats.
Should the building lose internet connectivity, the Pelican system would continue to function by following
the schedules and setpoints stored locally.
3. Carbon dioxide (CO2) sensors built into thermostats for monitoring of CO2 concentrations within spaces.

Based on distances between facilities and to eliminate the potential for large vehicles/trucks interrupting the
signal, a Gateway for each building is recommended. Additionally, if there is not an available port on a
router/switch in each building, repeaters can be utilized. However, they must be installed as high within the
structure as possible. The end result may be a combination of gateways and repeaters to ensure signal strength
and maintain remote accessibility.
Upgrade Interior/Exterior Lighting to LED
The intent of the project is to replace all fluorescent, incandescent, and HID lighting with LED lamps or new fixtures
to reduce energy use and maintenance costs. Some critical lights such as those in the restrooms will have an
emergency battery backup installed in case of a power outage, so that visitors and staff may exit the building
safely. As part of the scope of work, dirtied lenses will be cleaned before installation of replacement lamps, and
any damaged ceiling tiles will be replaced. Additionally, occupancy-based controls will be installed.
Occupancy sensors detect when the illuminated space is occupied, and subsequently turn lights off when the
space is not in use. Detailed information about the recommended replacement can be found in the section
titled “Appendix B – Lighting”.

Shannon Community Center
RCx of Existing HVAC Systems
The Shannon Community Center has 15 gas/electric split systems ranging in capacity from 3-tons to 5-tons. All
fifteen units are original to the building’s construction making them 13 years old at the time of the IGA. Since they
have not yet exceeded their EUL and have no operational or functional issues, Willdan does not recommend
replacing these systems within the next 3 years. Instead, Willdan recommends that retro-commissioning of the
existing systems be performed. It is recommended that retro-commissioning be performed on equipment every
few years to ensure that systems continue to operate optimally and that operating parameters are adjusted for
changes that may have occurred within the areas that are served which may impact the cooling/heating loads
and operating schedules.
The retro-commissioning effort that Willdan recommends includes:
Equipment schedules are to be reviewed and modified to capture unoccupied savings without
adversely affecting occupied conditions
Setpoints for occupied and unoccupied operation to be adjusted for optimal building performance and
energy efficiency
Outside air damper position optimized for energy efficiency and building ventilation requirements
Install New Generator at Shannon Community Center
Willdan evaluated the electric utility data over the time period between January 2018 and January 2020, and
determined that the building load maximum is 110.2 kVA, based on observed peak demand data and power
factor.
This project includes the installation of a new 150-kW diesel motor generator located in a weatherproof enclosure
at the Shannon Community Center to provide emergency back-up power to the entire facility in the event of a
PG&E PSPS event, which is when PG&E has turned off power in response to severe weather conditions to help
prevent wildfires and keep communities safe. A new fuel tank will be installed and sized to provide 72 hours of
continuous generator run-time. There will also be the option to use renewable diesel, when available, to reduce
emissions. The Shannon Community Center is listed in the Emergency Operations Plan as a shelter location, as well
as an alternate location for government, in case of emergency such as a natural disaster. Therefore, it is critical
that this facility has resiliency capabilities.
The generator will be mounted on a new concrete pad located directly outside of the main electrical room and
will be electrically tied to the existing automatic transfer switch. New power, control and communications will be
installed and routed underground.
Upgrade Interior/Exterior Lighting to LED
The intent of the project is to replace all CFLs, halogen lamps, and linear fluorescent tubes with LED lamps or new
fixtures to reduce energy use and maintenance costs. LEDs last 2-4 times longer than fluorescent lamps and can
be installed without ballasts to avoid another point of failure which may occur at light fixtures. As part of this
427
| Investment Grade Engineering Audit | Page 66
scope of work, dirtied lenses will be cleaned before installation of replacement lamps, and any damaged ceiling
tiles will be replaced. Additionally, occupancy-based and daylighting controls will be installed. Occupancy
sensors detect when the illuminated space is occupied, and subsequently turn lights off when the space is not in
use. Shannon Community Center’s lobby is well-lit by daylight outside the building during the day. In this area, this
project proposes to install daylight harvesting controls. These controls adjust lights to maintain the space’s target
lighting levels when adequate illumination through the building’s glazing is detected in the space. Detailed
information about the recommended replacement can be found in the section titled “Appendix B – Lighting”.

Fire Station #16
HVAC Systems
Fire Station #16 has four packaged gas/electric RTUs that serve all the occupied housing areas. The equipment
varies in capacity from 2-tons to 6-tons. All five units were installed as part of the facility’s 2006 remodel and are
approaching the EUL of 15-years according to ASHRAE. However, these systems were observed to be in decent,
functional condition and replacement can be deferred for the next 3-5 years. At that time, various options for
replacement can be considered, such as high efficiency replacements or a comprehensive VRF solution.
Install New Wireless, Internet Based Controls
Fire Station #16 has simple wall-mounted thermostats that provide temperature control at the zone level. As the
existing thermostats have standard scheduling capability, their energy saving control strategies, ease of
accessibility, and reporting can be improved upon. Additionally, there is an opportunity to standardize the
controls systems across the City’s facilities and expand throughout the City where DDC controls currently do not
exist.
This project recommends installing Pelican Wireless controls to further reduce energy consumption and costs, as
well as ease the time burden associated with maintaining individual thermostat settings throughout the City of
Dublin’s facilities. The Pelican Wireless thermostats would be connected to a single, web-accessible graphical
user interface (GUI) to allow for centralized schedule management, reporting, and troubleshooting all major
heating and cooling equipment throughout the City’s buildings. This system would allow individual zones to have
different occupied or unoccupied temperature schedules, as well as alert the building operators to errors and
routine maintenance.
Additional benefits of the Pelican system include:
1. The Pelican system does not use or rely on the building’s internal Wi-Fi or LAN networks for thermostat
communication. The Pelican gateway broadcasts its own wireless backbone, establishing a mesh network
that only talks to other Pelican devices, some of which act as repeaters themselves. This allows for minimal

(2) WR400 Repeaters
(7) TS250 CO2 Thermostats
(7) TA-1 Sensor Adapters (for supply air temperature display)
(7) Probe T-1 Supply Air Sensors (for supply air temperature display)

Replace Diesel Generator
The diesel generator at Fire Station #16 is original to the building’s construction and is close to its EUL. According
to ASHRAE, reciprocating engines have an EUL of 20 years, however, with proper maintenance engines can have
a service life of well over 25 years. This project will replace the existing diesel generator with a new generator for
resiliency purposes so that backup power to this critical facility is available in the event of PSPS events, which has
become more typical within PG&E territory in recent years.
Through the course of our evaluation, Willdan also considered BESS at the fire station. Given a sufficiently high
and peaky electric load, BESS can generate on-going savings through peak demand reductions or energy
arbitrage as well as provide limited resiliency power, helping to offset the initial system cost. However, in
comparison to conventional generator engines and given the lengthy PSPS outages that Dublin experiences,
BESS’s current market pricing is over 10 times more expensive for an equivalent backup solution. Therefore,
Willdan is not recommending BESS at the fire station for resiliency purposes at this time. Dublin may have another
opportunity to evaluate BESS through East Bay Clean Energy’s upcoming microgrid joint procurement in the near
future, which may offer better pricing. In any case, a future BESS installation will pair nicely with the on-site solar
and backup generator at all fire stations.

Fire Station #17
Replace HVAC Systems with High Efficiency Equipment
Fire Station #17 has four gas/electric split systems that serve all the occupied housing areas. There are two 3-ton
units and two 4-ton outdoor condensing units that are connected to indoor gas-fired furnaces, all of which are
original to the buildings construction of 2002 and have exceeded their EUL of 15-years, according to ASHRAE,
which is when major components are at risk of failing and ongoing maintenance costs begin to become
significant.
This project recommends proactively replacing the four split systems (indoor and outdoor units) with new, high
SEER units that exceed CA Title-24 efficiency requirements. The new units will be installed in the same location as
the existing units. Ductwork, electrical, natural gas, and condensate systems may be extended or slightly
modified to accommodate the installation of the new units. As the split system cooling coils are located within
mechanical rooms, the existing condensate lines are plumbed to neutralizing basins of approx. 5 gallons capacity
before they are discharged indirectly to the nearest floor sink.

Install Solar PV
Willdan recommends installing a small Solar PV system
at Fire Station #17 of 24kW. The system will be flush
mounted to the standing seam metal rooftops and will
have a tilt angle of 18 degrees above horizontal. The
system will include Boviet 445W Tier 1, CEC-listed
modules with a 12-year warranty and a 25-year linear
power output warranty, and SolarEdge 14kW inverters
with a 12-year warranty. Additional solar PV will
generate additional electricity to increase Dublin’s bill
savings at this facility and provide the foundation for
future zero emission resiliency projects throughout the
City. While this installation is small, it can be feasibly
done as part of this project because it is combined into
the larger scope of solar PV installations throughout the
City. A small system like this would be difficult to procure
on its own.
Fire Station #17 is an important emergency operations facility within Dublin, so resiliency is important. Willdan
considered installing BESS for economic and resiliency purposes, however, it was not economically feasible at this
time. Given the 48-72-hour desired resiliency, a diesel generator is the City’s best choice. Replacing Fire Station
#17’s generator is further detailed in the next section.

The Wave at Emerald Glen Park
Pool Control System Firmware Upgrades
The four bodies of water at the Wave Aquatic Center (indoor, activity, outdoor and slide pools) each have
dedicated circulation and filtration pumps that are controlled by the SPCS pump controller located in the
equipment room. Although there is nothing inherently wrong with the system or how it currently operates it is
imperative that the City keep the software packages up to date to mitigate issues from arising within the control
system and ensure that proper filtration and chemical circulation is not interrupted. This project proposes to
update the firmware to the most current BECSys7 Gigabit package.
Install Solar PV and Battery Energy Storage
Willdan proposes to furnish and install a 525kW
(DC) Solar PV carport system and a
500kW/1100kWh BESS connected in a
microgrid arrangement. This system is designed
to reduce overall operational costs at the
Wave and provide resilience during an
extended power outage. As The Wave is a
cooling center and shelter as part of the City’s
Emergency Operations Plan, it is crucial that
the facility has resiliency capabilities.
The Wave is the ideal type of facility to support
a more cost-effective deployment of a
renewable microgrid. Due to high energy
costs during normal operation (water
pumping, filtering, etc) and ample parking space, a large solar PV system and battery can generate significant
bill savings. Then during emergency operation scenarios, the large pumping loads, and the large solar PV and
large battery can support critical loads for extended periods of time.
The proposed 525 kW carport system will be in the south parking lot next to Central Parkway due to its ideal
configuration and proximity to the utility meter. It will have a tilt angle of 10 degrees above horizontal. The
system will include Boviet 445W Tier 1, CEC-listed modules with a 12-year warranty and a 25-year linear power
output warranty, and Chint 50kW inverters with a 10-year warranty. Excess generation that is not consumed by
site loads or the BESS can be credited to the adjacent Emerald Glen Park electric bills via the Net Energy
Metering Aggregation (NEM-A) tariff.
The proposed 500kW/1100kWh BESS will be manufactured by EnerGPort and has a 10-year warranty. The system
will be able to operate to offset peak loads and thereby generate bill savings, and also provide approximately 48
hours of resiliency during an extended outage without any additional recharge from the solar PV, or longer if the
sun is shining. During an outage, critical loads include the inflatable roof of the natatorium, emergency lighting,
and emergency services such as locker rooms and showers, which will provide support to emergency personnel
operating around the City.

Parks & Sports Fields
Install Solar PV
Fallon Sports Park
Adequate roof space is not available at this location
for a roof-mounted solar PV system. As such, Willdan
proposes to furnish and install a 59kW (DC) solar PV
carport system in the parking lot of Phase 2 of Fallon
Sports Park. The carport system tilt angle will be 7
degrees above horizontal. The system will include
Boviet 445W Tier 1, CEC-listed modules with a 12-year
warranty and a 25-year linear power output warranty,
and a Delta 60kW inverter with a 5-year warranty. This
system will produce electricity to offset regular loads
of the park and generate bill savings for the City, as
well as provide the foundation for future zero emission
resiliency projects throughout the City. This is the only
parking lot where solar is recommended because the
other sites have smaller loads, or are adjacent to sites
with large PV systems (such as Civic Center for Dublin Sports Grounds, The Wave for Emerald Park) that can credit
them via NEM-A. This site has a large enough electric lighting load that it can benefit from a small carport PV
system.
Upgrade Sports Field and Park Lighting to LED
Dublin Sports Grounds, Emerald Glen Park, Fallon Sports Park, and Kolb Park
Several sports fields and courts in the City are currently illuminated by the outdated, inefficient metal halide
lamps. While these lamps are bright, they use a large amount of energy and burn out much faster compared to
the modern solution of LEDs. Willdan recommends the City of Dublin upgrade the existing sports lighting to LED.
LED sports lighting systems require significantly less maintenance and have a significantly greater lamp life than
the metal halide systems they replace. In fact, most LED sports lighting systems last for 300,000 hours of run time.
Long warranties make the investment in LED lighting a long-term savings opportunity in maintenance as well as
energy savings. Control systems assist with both energy savings by only running lights when needed, as well as
monitoring the system for potential failures. Measurable consistency is an important factor in light quality. Metal
halide lights degrade in brightness and color-consistency over time, but LED sports lights maintain a consistent
level of brightness and color-accuracy, improving the long-term light quality on the playing field. In sports events
with high-speed ball movement, light quality is an important consideration.
Light pollution can be significantly reduced with an LED sports lighting system. Pollution in the form of light spill is
not only a waste of valuable energy, it is a destructive nuisance to neighbors and wildlife. LED lighting is
directional, so the ever-present glow of light seen above a typical ballfield can be eliminated. The light cut-off
features of modern LED lighting systems reduce neighbor complaints and the overall waste of spilled light.
439
| Investment Grade Engineering Audit | Page 78
Additionally, with the imminent utility Time-of-Use shift to 4-9pm, there is a significant economic benefit to
reducing the electrical load of the City’s sports lighting during this time.
Willdan evaluated two manufacturer options to develop the best possible solution for the City which ultimately
resulted with MUSCO Lighting as Willdan’s recommendation and proposed solution for the City. The two
manufacturers that were evaluated are considered by many to be the two leading manufacturers of LED sports
lighting: MUSCO Lighting and Ephesus Sports Lighting (by Cooper Lighting).
T ABLE 23. E XISTING AND P ROPOSED S PORTS F IELD LIGHTING S UMMARY
Both manufacturers offer a parts and labor warranty. This means that if installed fixtures burn out or otherwise
break before the end of the warranty period, the manufacturer will install a replacement fixture at no cost to the
City. MUSCO offers a 25-year warranty for fixtures. In this scope of work, this includes the baseball, softball, soccer,
and basketball fixtures located at Dublin Sports Grounds and Fallon Sports Park. For the remaining scope,
including basketball courts, tennis courts, and ska te parks, they offer a 10-year warranty. Ephesus offers a 10-year
warranty across all scopes of work.
The ability to control the lighting system is important through both a city operation and an energy savings
context. The lights need to be on during sporting events, which can be irregular and therefore not able to be put
on a typical timeclock. By controlling the fixtures, the city’s sports events will be fully lit, and energy is not wasted
when there are no events taking place, since the lights would be turned off. MUSCO and Ephesus both offer
controls strategies, although they differ in functionality. MUSCO’s product, ControlLink, is already installed in the
fields with existing MUSCO lighting. ControlLink offers remote access, as well as the capability of scheduling out
the lighting for future events. ControlLink has the additional benefit of functioning as a diagnostic tool – the
software will warn operators if a light is consuming an abnormal amount of power or running at too high of a
temperature, which can be a sign of a problem or potential failure. Operators can then respond proactively,
rather than suffer a failure during an event or usage. In contrast to MUSCO’s ControlLink, Ephesus offers a Hub
control solution, with a few different options. The Hub utilizes an airmesh system, which is a wireless hub that
connects to 120V at the facility. Multiple fields can be run off a single box, and Ephesus commissions the fixtures
after installation to ensure they all communicate correctly with the box and there is full fixture control at the
facility level. Facility managers can schedule out on/off times for up to two years and can choose which lights
need to be on and which ones don’t. If there is an event where only half the field needs to be lit, the lights
illuminating the unused half can be shut off to conserve energy. The controllability goes down to the individual
440
| Investment Grade Engineering Audit | Page 79
fixture level. There are several ways the Ephesus Hub can be managed. If there is not existing internet at the
installation facility, the box creates its own IP address rather than connecting into the existing one. This means that
there is full access at the site level. If the City wants remote access, it can activate Verizon cellular service or
hardwire and BACnet in, which is paid separately through Verizon and is not accounted for in the pricing
enclosed in this report. In contrast to this, ControlLink and all its features come with the MUSCO product and are
included in its pricing.
A feature exclusive to MUSCO is their BallTracker technology. LED lighting is very directional, illuminating only the
playing surface, which is excellent for reducing light pollution. However, problems arise when play objects like
baseballs are sent high above the play field – they become extremely hard to see. MUSCO’s solution, the
BallTracker, consists of small, specialized low-level up lights that are targeted above the play surface. This creates
a contrast against the night sky that allows players to see the ball more easily, while avoiding sending glare into
the surrounding neighborhood. While Ephesus does not offer a solution such as BallTracker, their lighting system is
designed to illuminate both the field surface and play area above it, so aerial objects can still be easily seen.
With all factors considered, Willdan recommends the selection of MUSCO for the sports field lighting LED
improvement project. The proven MUSCO lighting technology and result provides extra value. Additionally, the
City of Dublin’s existing relationship and experience with MUSCO will provide continuity in existing function and
maintenance. Finally, the 25-year warranty on the larger lighting systems ensures that the City of Dublin will have
no concerns about sports field lighting for decades.
Improved Parks Lighting Recommendation
Willdan explored all city parks for the potential need to improve lighting conditions. Three locations were
identified. These locations include Mape Memorial Park, Ted Fairfield Park, and Alamo Creek Park.
Mape Memorial Park
Mape Memorial Park is located at 11711 Mape Way. This park is approximately 2.6 acres, and it includes a
playground, open green space, a walking trail, sand volleyball, public restrooms, picnic area, and a pedestrian
bridge providing access from Mape Way to commercial properties at the intersection of Amador Valley Blvd.
and San Ramon Rd.
Panoramic view of playground area
Existing Lighting Systems:
The walkway around the park perimeter is illuminated by four, 60W corncob LED area lights on 16’
poles.
The restroom has one small LED wall pack installed on the north exterior wall.
441
| Investment Grade Engineering Audit | Page 80
Observations:
The pedestrian bridge on the east side of the park spans a small creek, and it is covered by a thick canopy of
mature trees. The trees prevent both natural light and artificial light from illuminating the bridge.
The picnic area at the north park entrance is partially illuminated by the light on the restrooms, but that light
does not provide adequate light levels (to meet IES design guidelines) for the walkway from the shelter to the
pedestrian bridge. According to IES publications: IESNA RP-33-2014, IESNA DG-5-94, and IESNA DG-1-03,
exterior walkway illumination should be ≥1 footcandle. To achieve these design recommendations, additional
lighting should be added along the walkway that connects these two park features.
Recommendations:
Install a new light pole on the south end of the pedestrian bridge, matching the existing light pole on the
north side. This additional light will fully illuminate both the bridge and the area immediately surrounding the
south bridge entrance.
Add new light poles along the walkway between the north park entrance and the pedestrian bridge. This
additional lighting will better illuminate the pathway between Mape Way and the pedestrian bridge.
Add new lighting on the west side of the playground to eliminate dark spots in that area.

Ted Fairfield Park
Ted Fairfield Park is located at 3400 Antone Way. This park is approximately 7.3 acres,
and it includes a playground, open green space, a walking trail, basketball court,
public restrooms, and two pedestrian bridges.
Existing Lighting Systems:
There are no plan drawings available for Ted Fairfield Park, but the following
systems were identified during a site visit (wattages and heights are approximate):
Eight 150W HID area lights on 16’ poles along the perimeter walkway.
Observations:
The pedestrian bridge on the north side of the park spans a small creek to reach Oak
Bluff Lane. The residential area across from the park has minimal area lighting. This
means that the bridge itself is only illuminated on the south side, creating underlit
areas on the north end of the bridge (especially for pedestrians leaving the park).
No exterior light fixtures were found on the restroom building.
Many of the existing light pole base hardware is damaged and in need of
replacement.
Recommendations:
Our recommended solution is to add an LED area light on a 16’ pole next to the
bridge entrance. This light will match the area light on the south side of the bridge.
Add wall packs on the exterior walls of the restroom building. Two small wall packs on
the southeast wall and one small wall pack on the southwest wall will provide
improved light coverage near the restroom building.
Replace damaged light pole base hardware.
Alamo Creek Park
Alamo Creek Park is located at 7601 Shady Creek Road. This park is approximately
5.3 acres, and it includes a playground, open green space, a walking trail, a public
restroom, a picnic area, one basketball court, and a pedestrian bridge providing
access from the south end of the park to Wildwood Road.
Existing Lighting Systems:
Fourteen 60W corncob LED area lights on 16’ poles along the
perimeter walkway.
Two double-headed 60W corncob LED fixtures on 16’ poles next
to the parking area.

| Investment Grade Engineering Audit | Page 82
Observations:
The parking lot on the west corner of the park has two light poles on the southeast side of the lot. The
northwest side receives some light spill from the street lighting on Shady Creek Rd, but not enough to
provide adequate light levels (to meet IES design guidelines) at the parking lot.
The pedestrian bridge on the south end of the park has one light pole on the south side (along Wildwood
Road). The north entrance to the pedestrian bridge should also be illuminated.
The playground receives some light spill from the lights along the walking path. Because the playground
is next to the creek and the entrance to the pedestrian bridge, additional lighting is recommended.
Recommendations:
Install two additional light poles on the northwest edge of the parking lot to illuminate the entire parking
lot.
Our recommended solution is to add an LED area light on a 12’ pole next to the bridge entrance. This
light will match the area light on the south side of the bridge.
Install new light fixtures, in addition to the existing, on the two poles in the playground. These light fixtures
will fully illuminate the playground area, making it a safer environment.

Traffic Signal Resiliency
The City of Dublin has experienced several Public Safety Power Shutoff (PSPS) events
where Pacific Gas & Electric (PG&E) has turned off power in response to severe
weather conditions to help prevent wildfires and keep communities safe. These PSPS
events can last up to 3-4 days and impact the City’s traffic signal operations by
going dark for the duration of the outage. During power outages, signalized
intersections typically lose all functionality. Whether the outage is a few seconds or
an extended period of time, safety at the intersection is compromised.
To mitigate future PSPS events during the wildfire season or other power outage
events and natural disasters, Willdan has evaluated the implementation of traffic
signal resiliency projects to provide backup power to maintain full operation of the
City’s traffic signal system at 22 key intersections. Twenty-one of the intersections
have existing traffic signal systems, while the last intersection has not been
constructed yet.
A few notable desired outcomes of this project include the following:
Supply up to 72 hours of backup power at the most critical intersections
to provide continuous full operation of traffic signal systems
Keep larger intersections on full operation, while smaller two-lane
intersections can be kept on flashing red
Automated system where battery backup system and/or generator
automatically turns on to supply power during power outages
Select system components that are easy to access and maintain
Deploy battery backup system that includes management software
that provides alerts and system health status
Aligns with the goals of the City’s Climate Action Plan by identifying
and implementing microgrids to enable uninterrupted power during
times of grid instability, which supports Measure CF-2
Use of battery power and fuel cells as backup power supports the City’s
CAP goals to reduce GHG emissions, as current backup power is
provided by diesel generators
Willdan evaluated the feasibility of providing up to 72 hours of backup power to the
traffic signals using only BBS. Willdan also evaluated the option for the City to have
sets of spare batteries stored and charged at City’s Corporation Yard that can be
used to swap out batteries at each intersection as they become depleted during a
power outage. The details of these evaluations can be found in the Memo found in
“Appendix C - Traffic Resiliency”; but in summary, neither of these options are
feasible when it comes to providing 72 hours of traffic signal operations running only
on BBS.

In order to satisfy the City’s goals of multi-day runtimes, low maintenance, automation, management software,
and meeting the City’s Climate Action Plan goals, Willdan recommends the implementation of the Altergy fuel
cell systems at select priority intersections and install Clary BBS for the intersections that do not currently have a
BBS in place. The recommended backup power system type and duration is provided in the following table for
each intersection.

Hydrogen Fuel Cell Safety & Protection
Altergy hydrogen fuel cell systems are not without risk, but research has shown that hydrogen cylinders rarely
rupture due to impact. Most ruptures of pressurized steel cylinders will occur from over pressurization. All hydrogen
cylinders supplied by Altergy meet or exceed DOT 3AA standards for safety and include CGA-350 fittings that
feature an integrated pressure safety device (PSD) in the form of a rupture disk for instantaneous pressure relief.
DOT requires all steel cylinders to be recertified every 5 years with hydrostatic testing to ensure the tanks meet
DOT standards. In addition, hydrogen vendors will not fill cylinders that are beyond 5 years from their last
certification. The hydrogen gas in a cylinder is 99.95% pure, so that the contents are not flammable unless they
have an egregious leak to the atmosphere. Hydrogen itself, although flammable in the presence of oxygen,
migrates quickly upward, unlike most other fuels used in power generation, and it also burns cooler, becoming
less of a threat than liquid or heavier gas fuels. Hydrogen is lighter than air and has a rapid diffusivity (3.8 times
faster than natural gas and 11.8 times faster than gasoline), which means that when released, it dilutes quickly
into a non-flammable concentration. Hydrogen rises 2 times faster than helium and 6 times faster than natural gas
at a speed of almost 45 mph (20m/s). Therefore, unless a roof, a poorly ventilated room or some other structure
contains the rising gas, the laws of physics prevent hydrogen from lingering near a leak.
To further minimize concerns regarding impact to the hydrogen fuel cells, some agencies have installed bollards
around the fuel cell cabinets to provide some impact protection. As hydrogen fuel cells have been deployed to
provide resiliency for varying purposes, including telecommunications, the image below provided by Altergy,
illustrates the growing use of these systems throughout the region.

Streetlights
Upgrade Dublin Ranch Street Light Assessment District Streetlights to LED
LED streetlights have the same benefits as the sports field lights and interior lights mentioned in this report.
Replacing or retrofitting the existing metal halide and sodium vapor streetlights with LED technology will reduce
the total energy costs while improving the safety and security of the streets and roadways. Because the
streetlights within the Dublin Ranch Street Light Assessment District are decorative types, Willdan recommends
retrofitting the existing fixtures with LED lamps and drivers to preserve their architectural appearance instead of
replacing.
Retrofitting the existing streetlight fixtures is a cost-effective method for achieving many of the benefits that come
with LED installations. However, some of the factors that will be limited due to use of the same fixture housing, not
specifically designed to work with the LEDs to be installed, are beam spread, controllability, and longevity. Based
on the City’s inventory and from Willdan’s preliminary inspections, 1,574 fixtures in the Dublin Ranch Street Light
Assessment District have been identified to be retrofitted to LED. As this is a fairly large quantity of light fixtures
which will be visible to the public, Willdan proposes to perform a few mock-ups or test installations to ensure that
the end product will be to Dublin’s standards prior to procuring all material. More information regarding the
existing and proposed retrofits can be found in Appendix A – LED Lighting Upgrades.

EV Charging & Infrastructure
Public Safety Complex
After reviewing Dublin’s plans for
vehicle replacement in 2021-2025 from
the EBCE Fleet Electrification report,
Willdan proposes the installation of (6)
Level 2 chargers to handle vehicle
charging and (1) 220V outlet for
motorcycle charging to handle the
imminent replacements in 2021-2022.
The existing (5) charging ports at the
PSC are not behind the existing fence,
and therefore would need to be
shared with the public. To ensure
adequate charging opportunities, the
proposed chargers will go behind the
gate and will be dedicated to the
Police fleet.
Willdan will also create (9) other “EV Capable” Police spaces to account for the additional fleet electrification by
2025 (mostly motorcycles). In this case, electrical infrastructure and solar production are sized and installed to
handle this additional load without major alterations in the near future. When the time is ready to install the
charging stations themselves, the infrastructure needed to support the above-ground stations will already be
installed as part of this project.
All EV Chargers would be installed behind a new meter on PG&E’s BEV-1 rate, which is advantageous for EV
charging, and demand charges sold in blocks.
Willdan will install a 136 kWdc solar PV system targeted to produce 212,000 kWh/year to offset the use of the PSC
and the projected future EV charging loads. The system installed will be a T-shaped carport in the front of the lot
and the roof on the south side of the building.
450
| Investment Grade Engineering Audit | Page 89
Dublin Sports Grounds
After reviewing Dublin’s plans for
vehicle replacement in 2021-2025 from
the EBCE Fleet Electrification report,
Willdan proposes the installation of (14)
dual-port Level 2 chargers to provide
electric vehicle charging to (28)
spaces. Willdan will also install an
additional 2 DC fast chargers to the
scope as the site is a prime candidate
for fast chargers given its close
proximity to the main thoroughfare in
Dublin and Interstate 580.
Willdan will also create up to (42) other
“EV Capable” spaces to account for
the additional future vehicle electrification. This proportion of spaces is in line with Dublin’s Reach Code for 25% of
parking spaces to be EV Capable. In this case, electrical infrastructure and solar production are sized and
installed to handle this additional load without major alterations in the near future. When the time is ready to
install the charging stations themselves, the infrastructure needed to support the above-ground stations will
already be installed as part of this project.
All EV Chargers would be installed behind a new meter on PG&E’s BEV-2 rate, which is advantageous for EV
charging, and demand charges sold in blocks.
Willdan will install a 200 kWdc solar PV system targeted to produce 321,000 kWh/year to offset the use of the
projected future EV charging loads. EBCE calculated that the load from public charging would be roughly
277,000 kWh/year from the charging of 20 Nissan Leafs for hrs/day. Willdan took this information and further
increased the solar PV generation to target 321,000 kWh annually, to account for the DCFCs that are also being
proposed. This breaks down to 1,000 hrs/charger per year, which is between 2-3 hours of average use per
day. The system installed will be a T-shaped carport in the DSG parking lot.
451
| Investment Grade Engineering Audit | Page 90
Rebates & Incentives
The Willdan team is leveraging three main sources of incentives and rebates for this project to reduce up-front
capital costs: PG&E’s 3rd Party Public Sector Energy Efficiency Program, PG&E’s Custom/Deemed Rebates, and
the SGIP. The first opportunity for incentives is PG&E’s Public Sector Energy Efficiency Program, run by Willdan. This
program offers incentives for customers within the public sector to retrofit their existing lighting and mechanical
equipment with more energy efficient equipment. While PG&E’s Custom/Deemed Rebates and SGIP are not
implemented by Willdan, Willdan will facilitate the incentive application and approval processes on the City’s
behalf. Additionally, there is the potential for future partnering opportunities with EBCE, which may result in an
additional source of funding for these projects.
Pacific Gas & Electric Public Energy Efficiency Program Incentives
Some interior and exterior lighting opportunities in the City of Dublin are eligible for PG&E’s custom incentive
program for government and K-12 facilities. These incentives are paid out for eligible measures based on the
energy saved and the total project cost for installing new qualifying LED fixtures. The LED fixtures must be Design
Light Consortium (DLC) certified, and greater than a specified lumens per watt (LPW) to qualify for incentive. The
incentive amount is calculated through a deemed savings tool that accounts for the energy reduction based on
assumed fixture run hours, reduction in wattage between old and new fixtures, and the type of lamp being
upgraded. De-lamping is not eligible for incentive.
Pacific Gas & Electric Custom and Deemed Rebates
In addition to the public program energy efficiency incentives described above, PG&E offers deemed upstream
rebates for several measures. Qualifying new high efficiency HVAC units are eligible to receive incentive based on
their tonnage, type, and efficiency. The incentive amount is calculated on $/ton basis. The new boiler at the Library
also falls under this program’s custom incentives. These incentives are paid directly to the manufacturer, but they
still reduce the overall cost of the project.
For more information on PG&E’s deemed rebates, please visit their website at https://www.pge.com/en_US/large-
business/save-energy-and-money/facility-improvement/custom-retrofit.page?WT.mc_id=Vanity_customized.
Battery and Energy Storage System Incentives
California’s SGIP is the best option for incentives. The 2021 SGIP, Step 4 incentive is $0.30/Wh for Energy Storage
Systems (ESS) not claiming a federal Investment Tax Credit (ITC), Larger projects, such as this one, that are greater
than 10 kW will receive 50% upfront and the rest paid each year as a Performance-Based Incentive (PBI) over a 5-
year period. The methodology for calculating an SGIP incentive is dynamic and based on several factors, including
the hourly duration of the ESS, the total energy capacity (kWh) of the ESS, for PBI projects if the ESS cycles at least
104 full discharges per year. The sum of the SGIP incentive and other incentives received for the project may not
exceed the total eligible project costs.

Disclaimer
The incentives and rebate estimates in this report have been reviewed for technical accuracy and are believed
to be reasonable and accurate, however, for factors beyond our control including project delays, actual results
may differ. As a result, Willdan is not liable if projected incentives and rebates are not actually achieved. The
incentive and rebate offerings are not to be construed either as firm or guaranteed. As PG&E’s incentive
programs have been newly refreshed for 2021, Willdan is still verifying measure and site eligibility to confirm actual
incentive amounts. Throughout this process Willdan will work with the City of Dublin to secure the maximum
possible incentives & rebates, which will be paid directly to the City where applicable.

Upgrade Interior and Exterior Lighting to LED
Many facilities in the City have not yet been upgraded to LED (light emitting diode) technology, instead
relying on outdated and inefficient fluorescent, metal halide, or incandescent lamps for illumination.
Through a competitive bidding process, Willdan selected Envocore as the lighting partner for upgrading
internal and external fixtures, as well as park lighting. Willdan & our lighting partner conducted a detailed
lighting audit for each of the facilities to determine the appropriate fixture replacements, provide turn-
key installation pricing with guaranteed energy cost savings. The fixture selections are based on current
space lighting density, space density requirement, existing fixture type, and several other factors, with an
end goal of proper lighting conditions and increased energy efficiency for the facility.
The table below shows the estimated yearly energy savings for the facilities audited.

Lighting retrofits are an economical solution that involves reusing the existing fixtures and replacing the
fluorescent lamps with LED tubes. To do this, several modifications must be made to the fixture. The
existing ballasts (magnetic or electric) will be removed, eliminating maintenance concerns due to
replacing these failure-prone devices. In some instances, the tombstones or sockets must be replaced to
accommodate the new LED tubes. Lastly, the fluorescent lamps are removed and replaced with LED
tubes.
Performing an LED retrofit offers a significant improvement when compared to the existing fluorescent,
HID, and incandescent technology. The first advantage is the minimized upfront cost in reusing the
existing fixture housing where possible. Many of the observed fixtures during the audit appeared to be in
good working condition. A good cleaning of both the pan and the lens can provide a solid foundation in
which the new lamps can be installed.
Most fluorescent lamps have a rated service life of around 25,000 hours. This means that over the life of
the lamp, the light output is considerably less towards the end of its life compared to when initially
installed. Most LED tubes are rated for an L70 life of over 50,000 hours. L70 refers to the expected life of
the LED tube at which the output will be 70% of its initial rating. With LEDs lasting more than twice as long
as the existing fluorescent tubes, the overall appearance of brightness should be maintained throughout
the life of the lamp more uniformly than with the fluorescent technology.
With LEDs lasting more than twice as long as a standard fluorescent’s 25,000 hours, maintenance is
minimized, allowing employees to focus efforts on other important tasks. The removal of the ballasts
minimizes the amount of time and resources spent to replace these pieces of equipment. Lasting

upwards of 50,000 hours, the lamps will not need attention for many years after the fluorescent lamp
would have needed attention. In addition to interiors, Envocore surveyed both building exterior lighting
and park walkway lighting. Well-designed outdoor lighting is cost-effective, controls light by directing it
where it is needed, reduces glare, distributes illumination evenly, and reduces light trespass. The most
common lamps used for outdoor lighting are HID metal halide, high-pressure sodium, and mercury vapor
lamps, which is what is currently installed in some of the City’s building exteriors and parks.

Measurement & Verification Plan
The Measurement & Verification (M&V) Plan provides a detailed explanation of the process for quantifying
savings delivered by an Energy Conservation Measure (ECM). This provides a degree of objectivity that is
absent if the savings are simply evaluated after the implementation. M&V demonstrates how much energy
the ECM has avoided using, rather than the total cost saved. The latter can be affected by many factors,
such as energy prices. The M&V process enables the energy savings delivered by the ECM to be isolated
and fairly evaluated.
The plan proposed in this report is subject to change based on the energy conservation measures selected
for the implemented project. The intent of each M&V option is to accurately identify, and report savings
generated as part of the ECM without incurring excess cost to the customer in obtaining those
measurements. This report identifies the methodologies to be executed when performing the proposed
International Performance Measurement and Verification Protocol (IPMVP) options related to the ECMs to
be implemented at each facility.
Proposed Annual Savings Overview
One of the key goals of this project is to achieve energy savings through upgrades to facility mechanical
and HVAC infrastructure, improvements to the controls and associated sequences, lighting of interior and
exterior spaces as well as select sporting fields, installation of solar photovoltaic generation equipment
with battery storage, upgrading streetlights throughout the city to LED, and other miscellaneous
improvements.
When selecting an appropriate method for measuring energy savings using the IPMVP options, all ECMs
for a given facility should be considered to ensure that interactive energy components are properly
addressed. As such, the below table has broken the project energy savings into either their associated
facility, or an appropriate grouping for locations that are not defined by a physical structure.

M&V Methodology Selection
Willdan strives to utilize the method of measurement and verification that is the best balance of cost and
benefit to the customer by adhering to the recommendations of the IPMVP. The method selected for
each ECM allows for objective and quantifiable energy savings to be achieved without incurring
excessive cost to the customer. This is accomplished by verifying the installation and operation of
equipment during post-installation, and utilizing existing metering devices, so that reasonable
assumptions can be made for establishing agreed upon baselines, operating hours, and equipment load
profiles. The following table outlines the most effective M&V option that will be utilized for each ECM
proposed. If significant modifications are made to the scope of work at a given facility, the M&V option
will be modified appropriately and defined before the onset of the savings agreement.

Option A – M&V Plan and Savings Calculation Methods
DESCRIPTION OF ECM TYPES MEASURED
This ECM upgrades the lighting systems in 14 City of Dublin, California locations. Existing standard-
efficiency lighting fixtures will be upgraded to include energy-efficient LED components. The energy cost
reduction is due to lowering the power requirement (kW) and associated kWh of the lighting fixtures
through the use of efficient lighting equipment. Replacing existing lamps and ballasts with new
equipment will virtually eliminate the material cost of spot re-lamping for several years.
M&V GUIDELINE AND OPTION
The Measurement and Verification (M&V) methodology to be employed for this project is consistent with
Option A as described in the U.S. Department of Energy Federal Energy Management Program (FEMP)
publication, M&V Guidelines: Measurement and Verification for Federal Energy Projects, Version 4.0.
M&V ACTIVITIES
The intent of this M&V Plan is to verify that the lighting fixtures operate and perform as specified in the Final
Proposal.
1. Baseline Measurements:
The Baseline for this ECM was developed by a thorough and detailed audit of the lighting
equipment installed in the individual buildings. The audit produced a room-by-room list of existing
lighting systems and measured light levels (where readings could be taken). Baseline fixture wattage
is based on spot measurement of a sample of fixtures within each electrically significant fixture
configuration. Lighting burn hours are based on typical hours by space room type. The sample sizes
for the spot measurement and logging are selected to achieve a precision level of 20% and a
confidence level of 80% according to Table D.2 in the FEMP M&V Guidelines.
2. Post-Installation Measurements:
608
| Appendix E – Measurement & Verification Plan| Page 156
Post-Installation fixture wattage measurements will be taken to achieve a precision level of 20% and
a confidence level of 80% according to Table D.2 in the FEMP M&V Guidelines. Post-Installation light
level readings will be taken where possible to ensure sufficient lighting exists in areas that have been
retrofitted. Lighting burn hours will be consistent with the baseline assumptions and will not be
measured.
3. Savings Calculations and Report:
The room-by-room savings calculations will be updated Post-Installation to reflect the actual count
of fixtures upgraded as part of this ECM, the actual equipment installed, and updated fixture
wattage measurements. This file will be updated one time and the results will be reported in the M&V
Report.

GUARANTEED ENERGY SAVINGS CALCULATION METHODS
The proposed high-efficiency LED lighting equipment requires less electric power (watts) than the existing
lighting equipment, resulting in a significant reduction in energy consumption. Calculation of energy,
demand, and cost savings are based on accepted engineering principles. Lighting energy savings are a
summation of lighting fixture kW demand reduction and lighting fixture kWh consumption reduction.
609
| Appendix E – Measurement & Verification Plan| Page 157
A room-by-room lighting survey was conducted. Existing and proposed lighting system descriptions,
operating schedules, and utility rate structures are inputs in the Excel spreadsheet. Annual energy savings
and installation specific data was summarized in the program output.
ENERGY BASELINE DEVELOPMENT
The baseline is that set of parameters that describes the lighting energy and power during the baseline
year for the lighting fixtures being retrofitted and/or replaced. An accurate measurement of Baseline is
necessary to facilitate accurate measurement and verification of the Energy Savings Guarantee.
Baseline conditions generally include physical, operational, and energy use data on the facility and
systems. This section identifies baseline performance and operating factors that influence energy
consumption, and how their values will be determined through observations and measurements. This
Baseline shall be used to determine whether Actual Energy Savings exceeds or falls short of the Energy
Savings Guarantee.
VARIABLES AFFECTING BASELINE ENERGY USE:
The Baseline performance factors include space light levels, fixture wattage (efficiency), and lighting
fixture burn hours.
BASELINE SYSTEM PERFORMANCE FACTORS:
The Baseline system performance factors include space light levels, fixture wattage (efficiency), and
lighting fixture burn hours.
BASELINE DATA ANALYSIS:
The data collected during the detailed energy study was input into an Excel spreadsheet. Field
measured and logged data were used in the spreadsheet to accurately represent Baseline lighting
system operating parameters. The following equations methodology was used to determine baseline
electrical consumption and demand.
4.Fixture Energy Consumption: Samples of the most common fixture types will be measured to determine
the fixture power consumption under actual operating conditions.
LCB = ∑ Pre-Retrofit System Consumption
Where,
∑ Pre-Retrofit System Consumption = ∑ (Measured Fixture Watts x Annual Operating Hours)
LCB = Lighting Baseline Electrical Consumption (Lighting specific, Includes interior and exterior lighting)
5.Fixture Power Demand:
LDB = ∑ Pre-Retrofit System Power x 12 months
Where,
∑ Pre-Retrofit System Power = ∑ (Measured Fixture Watts x Diversity Factor)
610
| Appendix E – Measurement & Verification Plan| Page 158
LDB = Annual Lighting Baseline Electrical Demand (Lighting specific, Includes interior and exterior
lighting)
Diversity Factor = Percentage of time the fixtures are on when the peak demand is set (stipulated)
STIPULATED VARIABLES:
6. Annual Operating Hours – Run hours for light fixtures will not be measured; operating hours are based
on typical hours of occupancy for each space type.
7. Demand Factor – Demand Factor is stipulated based on typical probabilities that a given room type
will be illuminated when the building’s peak demand is set for each month.
8. Coefficient of Performance of the cooling system – Published efficiency data is used for cooling
systems in each building. Impact of this variable does not justify the cost to measure.
9. Heating System Efficiency – Published efficiency data is used for heating systems in each building.
Impact of this variable does not justify the cost to measure.
SAVINGS OR BASELINE ADJUSTMENTS:
Not applicable.
POST-INSTALLATION M&V ACTIVITIES
INTENT OF POST-INSTALLATION M&V ACTIVITIES:
The intent of the M&V Activities immediately preceding construction is to measure the energy savings
performance of the measures under this M&V plan for the purposes of satisfying the energy savings
guarantee.
VARIABLES AFFECTING POST-INSTALLATION ENERGY:
The Post-Installation performance factors include space light levels, fixture wattage (efficiency), and
lighting fixture burn hours.
POST-INSTALLATION DATA TO BE COLLECTED:
The light fixture electricity demand will be measured of each unique lighting fixture type at random
locations to achieve a precision level of 20% and a confidence level of 80% according to Table D.2 in the
FEMP M&V Guidelines. The electricity demand measurements for the sample of fixtures will be
extrapolated to similar fixture types within each specific population. Light levels will be measured in similar
locations in the same rooms as those taken during the detailed energy study. The savings spreadsheet will
be updated to reflect actual lighting fixture counts, the specific retrofits performed, and the measured
Post-Installation fixture wattage. The fixture burn hours will not be measured, but rather will be assumed
based on building operation schedule and typical run hours by space type. The updated ECM
calculation files will be provided as part of the Post-Installation Report.
POST-INSTALLATION DATA ANALYSIS:
611
| Appendix E – Measurement & Verification Plan| Page 159
The Post-Installation calculations will be updated to reflect the results of the Commissioning and Post-
Installation M&V effort. These calculations will determine actual savings achieved relative to the
guarantee.
PERFORMANCE PERIOD VERIFICATION ACTIVITIES:
No Performance Period M&V Activities will be performed by Willdan other than reporting of achieved
energy savings. Energy savings achieved for the purposes of measurement and verification of energy
savings will be determined based on one-time post-installation measurements.
M&V REPORTING
Willdan will provide an annual M&V report at least one year following project completion. The Annual
M&V Report will be provided within 60 days of the end of the 12-month performance period. M&V reports
will contain the savings associated with this M&V plan.
VARIABLES AFFECTING PERFORMANCE PERIOD ENERGY USE AND SAVINGS
For the purposes of the City of Dublin maintaining the energy savings performance during the
performance period, it is important the City of Dublin understands that building usage and lighting system
run hours need remain consistent from the Baseline Period through the Performance Period to maintain
savings levels. Furthermore, energy-efficient lamps need to be installed when any of the existing lamps
and ballasts burn out to maintain savings.
For the purposes of measurement and verification of energy savings and the energy savings guarantee,
the post-installation measurements and energy savings results will be used to determine performance
period energy savings.
PROPOSED ENERGY SAVING CALCULATIONS AND METHODOLOGY
ANALYSIS METHODOLOGY:
The proposed energy consumption was developed by modifying the existing fixture types and Baseline
fixture wattage on the Excel spreadsheet with anticipated Post-Installation values (manufacturer data).
Lighting burn hours remained constant for Baseline and Post-Installation scenarios. The first-year energy
savings is the difference between the energy used by the Baseline and Post-Installation systems.
ASSUMPTIONS AND DATA SOURCES:
1. Lighting fixture electricity demand was measured for a sample of electrically significant fixture
configurations and extrapolated by fixture type to all fixtures falling in the specific population.
Post-Installation fixture electricity demand was based on manufacturer data. The Post-Installation
fixture electricity demand will be measured for a sample of fixtures and the calculations updated
to reflect the measurements following installation.
2. Lighting fixture burn hours were based on typical hours of occupancy for each space type.
3. Existing light levels (lumens) meet IES recommendations
612
| Appendix E – Measurement & Verification Plan| Page 160
ENERGY SAVINGS CALCULATIONS
The following equations methodology was used to determine electrical consumption savings.
10. Lighting Energy Savings:
LCS(kWh) = LCB – LCP
Where,
LCB = Baseline lighting consumption (kWh)
LCP = Proposed lighting consumption (kWh)
LCB = FWB x OPHRS / 1,000
LCP = FWP x OPHRS /1,000
FWB = Baseline Fixture Watts (measured parameter)
FWP = Post-retrofit Fixture Watts (measured parameter)
OPHRS = Fixture Annual Operating Hours (stipulated values)
11. Determination of Dollars Saved:
Total Annual $ Savings = ∑ (Energy/Demand Savings x Contractual Energy/Demand Rates)
Where: Contractual Energy Rates = Utility rates defined in earlier sections
Option B– M&V Plan and Savings Calculation Methods
DESCRIPTION OF ECM TYPES MEASURED
The ECMs included all involve the installation of solar photovoltaic energy generation systems at 8
locations around the City of Dublin, and battery storage with optional generator backup at select
locations. Specifically, the energy savings is achieved through the generation of electrical energy by the
photovoltaic systems as a result of solar energy being converted to electrical potential. It is the savings
generated by the PV systems that is considered in this M&V plan. Savings achieved through battery
storage is not included as part of the M&V savings guarantee.
M&V GUIDELINE AND OPTION
The Measurement and Verification (M&V) methodology to be employed for this project is consistent with
Option B as described in the U.S. Department of Energy Federal Energy Management Program (FEMP)
publication, M&V Guidelines: Measurement and Verification for Federal Energy Projects, Version 4.0.
M&V ACTIVITIES
The intent of this M&V Plan is to verify that the solar PV array produces electrical energy and performs as
specified in the final energy agreement.
12. Baseline Measurements:
613
| Appendix E – Measurement & Verification Plan| Page 161
The power generated by the to-be-installed solar PV array will be measured by a meter installed at
the equipment level. Since the equipment does not exist prior to the implementation of the project,
there is no baseline to measure. Certain locations already have solar PV arrays, and the generation
of these arrays has been considered in the baseline when sizing the future arrays, but will not be
measured in the performance period.
13. Post-Installation Measurements:
Post-Installation generated wattage measurements will be recorded by data acquisition meters
installed on the equipment. These measurements will be recorded for at least 30 days deemed to be
considered typical.
14. Savings Calculations and Report:
Based upon the measurements taken during the post-installation performance period, the energy
generated by the solar PV array will be calculated and extrapolated to represent the energy
generation expected of the installed system for the annual performance period. These savings will
be provided in the annual M&V report.

GUARANTEED ENERGY SAVINGS CALCULATION METHODS
The proposed solar photovoltaic arrays are designed to produce an expected amount of energy in kWh
per year based on typical annual data. Calculation of energy, demand, and cost savings are based on
accepted engineering principles. Solar energy savings are a summation of facility kW demand reduction
and facility kWh consumption reduction.
ENERGY BASELINE DEVELOPMENT
Due to the method of energy savings and lack of baseline equipment, no baseline is required to be
developed for this ECM.
SAVINGS OR BASELINE ADJUSTMENTS:
Not applicable.
POST-INSTALLATION M&V ACTIVITIES
INTENT OF POST-INSTALLATION M&V ACTIVITIES:
The intent of the M&V Activities immediately preceding construction is to measure the energy savings
performance of the measures under this M&V plan for the purposes of satisfying the energy savings
guarantee.
VARIABLES AFFECTING POST-INSTALLATION ENERGY:
The Post-Installation performance factors include energy generated and time of energy generation.
POST-INSTALLATION DATA TO BE COLLECTED:
The solar energy generated (in kWh) will be measured at each solar installation throughout the city. The
time of generation will also be recorded in order to correlate the energy generated with the associated
offset of energy consumption reduction based on the utility rate at the site of generation. The weather
and solar incidence will be considered during the period of measurement to ensure that it represents a
typical period of solar production for the site in question. The updated ECM calculations will be provided
as part of the M&V report.
POST-INSTALLATION DATA ANALYSIS:
The Post-Installation calculations will be updated to reflect the results of the Commissioning and Post-
Installation M&V effort. These calculations will determine actual savings achieved relative to the
guarantee.
PERFORMANCE PERIOD VERIFICATION ACTIVITIES:
Energy generation as measured by the data acquisition meter will be monitored during the performance
period to inspect for anomalies. Should any erroneous data be discovered, investigation into the system
615
| Appendix E – Measurement & Verification Plan| Page 163
and measurement equipment will be performed to try and prevent future deficiencies. The period of
measurement will be adjusted as needed, but will remain within the annual performance period. Energy
savings achieved for the purposes of measurement and verification of energy savings will be determined
based on short-term post-installation measurements taken at the installed data acquisition meter.
M&V REPORTING
Willdan will provide an annual M&V report at least one year following project completion. The Annual
M&V Report will be provided within 60 days of the end of the 12-month performance period. M&V reports
will contain the savings associated with this M&V plan.
VARIABLES AFFECTING PERFORMANCE PERIOD ENERGY USE AND SAVINGS
The generation of solar PV energy is accomplished without any interaction from the City of Dublin. The
equipment should be maintained as prescribed by manufacturer specification, but so long as no
structure or impediment is erected to block the absorption of solar energy from the photovoltaic array,
energy should be generated as designed.
For the purposes of measurement and verification of energy savings and the energy savings guarantee,
the post-installation measurements and energy savings results will be used to determine performance
period energy savings.
PROPOSED ENERGY SAVING CALCULATIONS AND METHODOLOGY
ANALYSIS METHODOLOGY:
The proposed energy generated was developed by calculating the expected solar energy to be
supplied to an array installed in the locations specified in the current design documentation.
Considerations were made for solar incidence, typical weather, and potential shading sources. The same
calculations will be utilized to calibrate the existing model and extrapolate annual electric generation, or
savings, based on the measured quantities.
ASSUMPTIONS AND DATA SOURCES:
1. The solar panel efficiencies are expected to not decay significantly during the performance
period.
2. Time of use for solar levels and electrical rates are based on the utility rates provided and typical
solar data.
ENERGY SAVINGS CALCULATIONS
The following equations methodology was used to determine electrical consumption generation/savings.
The baseline consumption is considered 0 for all facilities with respect to this M&V measure. Only the
power generated by solar PV arrays installed as part of the energy agreement will be considered in the
savings calculation.
15. Solar Energy Generation:
616
| Appendix E – Measurement & Verification Plan| Page 164
SGS(kWh) = SGP - SGB
Where,
SGB = Baseline solar generation(kWh)
SGP = Proposed solar generation(kWh)
SGP= TMGP x TMPY
TMGP= Typical Monthly Generated Power(measured parameter)
TMPY= Typical Months Per Year (ratio of measured time period to a year)
Assuming 30 days is used for the measurement period the ratio value for Typical Months Per year would
result in the TMPY being 12.17months = 365 days / 30 days.
16. Determination of Dollars Saved:
Total Annual $ Savings = ∑ (Energy Generated x Contractual Energy Rates)
Where: Contractual Energy Rates = Utility rates defined in earlier section.
Option C – M&V Plan and Savings Calculation Methods
DESCRIPTION OF ECM TYPES MEASURED
The Library in the City of Dublin has multiple ECMs each with significant energy impacts on the facility.
Due to the magnitude of energy saving achieved through mechanical HVAC & Controls upgrades being
proposed at the facility, it is expected that the energy savings of the other ECMs, particularly the lighting,
will have interactive effects with this ECM and attempting to isolate and measure the savings achieved
for this facility would be difficult and expensive. Instead, it is proposed that the measurement and
verification be tracked at the main utility meter. Detailed write-ups of each ECM are included in the
proposed energy conservation measures section of this report.
M&V GUIDELINE AND OPTION
The Measurement and Verification (M&V) methodology to be employed for this project is consistent with
Option C as described in the U.S. Department of Energy Federal Energy Management Program (FEMP)
publication, M&V Guidelines: Measurement and Verification for Federal Energy Projects, Version 4.0.
M&V ACTIVITIES
The intent of this M&V Plan is to verify that the HVAC equipment and controls, lighting fixtures, and solar PV
array operate and perform as specified in the final energy agreement.
17. Baseline Measurements:
The baseline is that set of parameters that describes both the energy consumed in the Baseline Year
and the conditions that caused that consumption to occur. This set of parameters includes utility
617
| Appendix E – Measurement & Verification Plan| Page 165
consumption, facility utilization information, energy-consuming equipment data, weather data and
other information as may be necessary to describe the base year conditions.
18. Performance Period Measurements:
Monthly utility consumption and demand will be obtained from the utility bills for each building
during the performance period. Weather data will also be obtained for this same period to be used
to weather-normalize the baseline period’s consumption.
19. Savings Calculations and Report:
The savings calculations will be performed during the performance period. Results will be included in
annual energy savings report at the conclusion of the M&V period.

GUARANTEED ENERGY SAVINGS CALCULATION METHODS
Each unique ECM provides energy savings generally due to improved efficiency, eliminating parasitic
losses (energy being used and wasted), lowering run hours for energy consuming equipment, and
generation of electricity from solar PV. Detailed explanations of how each ECM saves energy is included
in the ECM write-up section of the IGA Report.
618
| Appendix E – Measurement & Verification Plan| Page 166
A precise building energy simulation model – detailed to reflect the actual building footprint and
construction, HVAC and other energy-consuming system, and calibrated to actual utility consumption –
was used to quantify energy savings for the ECMs included in this M&V plan. Willdan performed building
energy modeling using widely-accepted building energy simulation software called eQUEST. eQUEST uses
the DOE2 (US Department of Energy) simulation engine and provides a graphical package to aid in
constructing the building for the DOE2 environment.
Once the building energy model was calibrated, the software has features to allow for parametric
simulations of various system modifications to produce real-time changes in energy consumption.
Changes to the model represent implementation of proposed ECMs. ECMs were implemented as
parametric runs, or groups of component changes to the baseline inputs, to assess the energy savings of
each ECM individually. ECM’s were run simultaneously to account for the interactive energy effects of
the ECM combinations in each building.
ENERGY BASELINE DEVELOPMENT
The baseline is that set of parameters that describes both the energy consumed in the Baseline Year and
the conditions that caused that consumption to occur. An accurate measurement of Baseline is
necessary to facilitate accurate measurement and verification of the Energy Savings Guarantee. This set
of parameters includes utility consumption and demand data, weather, building physical and thermal
properties, energy consuming equipment and system parameters, space temperature setpoints and
schedules, facility use and occupancy schedules, and other information as may be necessary to
describe the base year conditions.
VARIABLES AFFECTING BASELINE ENERGY USE:
Any energy consuming device and of system connected to baseline energy meter affect energy use
with respect the guarantee. These Baseline performance factors include, but are not limited to, weather,
type and efficiency of equipment in use, equipment capacity, equipment quantity, equipment
utilization, building’s physical construction, building utilization, and HVAC system operating parameters.
BASELINE SYSTEM PERFORMANCE FACTORS:
The Baseline system performance factors include, but are not limited to, weather, type and efficiency of
equipment in use, equipment capacity, equipment quantity, equipment utilization, building’s physical
construction, building utilization, and HVAC system operating parameters.
BASELINE DATA ANALYSIS:
Monthly utility consumption and demand will be obtained from the utility bills for the Guarantee Meters
and this usage forms the basis of the energy baseline. The following equations methodology was used to
determine baseline electrical consumption and demand:
Baseline Energy Consumption (or Demand):
Baseline Energy Consumption = ∑ Tracked Utility Meters’ Consumption ± Baseline Adjustments
619
| Appendix E – Measurement & Verification Plan| Page 167
Where,
Baseline Adjustment = ∑ ± Routine Adjustment to reporting period conditions ± Non-Routine Adjustments to
reporting-period conditions
Routine Adjustments include, but are not limited to, weather and billing period length
Non-Routine Adjustments include changes in key conditions from the baseline period to the reporting period,
including, but no limited to, occupancy; hours of operation; changes to building function and use; changes
to operation, capacity or quantity of equipment or systems within the facility; and additions to the building.
BASELINE ADJUSTMENTS:
20. Causes for Routine Baseline Adjustment: Implicit in this measurement option is the necessity to account
for the effects of changes in weather or billing period length from baseline period to the performance
period so that the true savings (or cost avoidance) from the energy conservation measures can be
assessed.
Weather normalization will be employed to ensure that the impact of actual weather conditions is
eliminated from the Energy Savings Guarantee calculations. Normalization used solely for the purpose
of accurately accounting for the impact on Actual Energy Savings of the Scope of Work implemented
in conjunction with the project.
21. Causes for Non-Routine Baseline Adjustment: Implicit in this measurement option is the necessity of
identifying and accounting for the effects of changes to the facilities and conditions during the
measurement period that are beyond the scope of the measures installed. During the measurement
and verification period, all variables must have their energy impact accounted for if the true savings
from the energy conservation measure is to be assessed. Following is a partial list of changes that will
lead to adjusting the Baseline Energy Consumption:
building additions
changes in operating hours
remodeling projects
changes in usage patterns
equipment replacements
In the event that any non-routine adjustment is warranted because a change is made to the
Customer’s Premises that will impact energy consumption, Willdan will utilize existing building models
used to calculate Baseline Energy Consumption to update that Baseline Energy Consumption and
determine the impact that any such change will have on Actual Energy Savings and present Customer
a written analysis of the effects of the changes. Changes that are long-term or permanent will be
reflected in a change to the Baseline Energy Consumption. Temporary changes that affect energy
use will be calculated and added to the corresponding month(s) Actual Energy Savings.
Any changes made by Willdan to the Baseline Energy Consumption or saving calculations shall be
presented to Customer for approval. Customer shall have 30 days to protest recommended
modifications in writing, after which time change will be considered accepted. If Customer protests
any recommended modifications, Customer and Willdan will work together to establish mutually
acceptable modifications based on accurate building models showing the impact of changes to
facilities.
MEASUREMENTS AND ADJUSTMENT METHODOLOGY:
22. Adjusted Baseline Year consumption is calculated as follows for each fuel type:
620
| Appendix E – Measurement & Verification Plan| Page 168
Adjusted Base Year Consumption = Weather Independent Consumption + Weather Dependent
Consumption + Offset + Use and Modification Adjustments
or
Q = CD x (Ti – Ti-1) + CH x HDDi + CC x CDDi + Oi ± ∑Mi = Eb (electric usage)
Q = CD x (Ti – Ti-1) + CH x HDDi + CC x CDDi + Oi ± ∑Mi = NGb (natural gas usage)
Where:
Q = adjusted base year consumption
CD = a constant representing units of consumption per billing period day as calculated by model
Ti = ending date of current billing period
Ti-1= ending date of previous billing period
CH = a constant representing units of consumption per heating degree day as calculated by
model
HDDi = heating degree days in the current billing period
CC = a constant representing units of consumption per cooling degree day as calculated by
model
CDDi = cooling degree days in the current billing period
Oi = offset for the current billing period
Mi = other adjustments for the current billing period
23. Adjusted base year demand is calculated with a slightly different formula as follows:
Adjusted Base Year Demand = Weather Independent Demand + Weather Dependent Demand +
Offset + Use and Modification Adjustments
or
Db = DD x (Ti – Ti-1) + DH x HDDi / (Ti – Ti-1) + DC x CDDi / (Ti – Ti-1) + Oi ± ∑ Mi
Where:
Db = adjusted base year demand
DD = a constant representing units of demand per billing period day as calculated by model
DH = a constant representing units of demand per heating degree day as calculated by model
DC = a constant representing units of demand per cooling degree day as calculated by model
24. Weather Independent Consumption: Because utility meters are not always read on the same day of
the month, the number of days in a meter’s billing period frequently varies. The term, CD x (Ti – Ti-1), in
the above equation is used to account for this difference, where Ti – Ti-1, gives the number of days in
the guarantee year billing period. Thus, Weather Independent Consumption is the consumption per
day times the number of days in the guarantee year billing period. The approach is identical for
demand, except that the term DD is substituted for CD.
621
| Appendix E – Measurement & Verification Plan| Page 169
25. Weather Dependent Consumption: Change in weather between the base year and guarantee year
periods is accounted for with the term, CH x HDDi + CC x CDDi . Weather Dependent Consumption is
consumption per degree-day times the number of degree-days in the guarantee year billing period.
The balance point temperatures used as the basis of degree day calculations shall be those that result
in the best statistical fit, or highest R2 value. If the R2 value is lower than 0.65, the meter shall not be
weather normalized.
Demand is treated similarly. The exception being that degree-days per day is substituted for total
degree-days. This provides a measure of average daily weather intensity.
26. Offset: Offset is that portion of the energy consumption that cannot be accounted for with the
Weather Independent and Weather Dependent consumption. It is mostly attributable to seasonal
changes in facility use such as summer shutdown and holidays. An Offset figure is defined for each
billing period in the base year. Since the guarantee period may overlap two or more base year billing
periods, the guarantee period offset will be the weighted average of the base year offset for the
corresponding guarantee year period. Offset for the guarantee period is determined with this
equation:
Oi = O1 * dG1/dB1 + O2 * dG2/dB2 + … On * dGn/dBn
Where:
Oi = current guarantee period offset
O1 = base year period 1 offset
O2 = base year period 2 offset
On = base year period n offset
dG1 = days in guarantee period that overlap base year period 1
dG2 = days in guarantee period that overlap base year period 2
dGn = days in guarantee period that overlap base year period n
dB1 = days in base year period 1
dB2 = days in base year period 2
dBn = days in base year period n
n = number of base year periods overlapped by guarantee year period
27. Other Adjustments:
Additional adjustments to the base year may be made to compensate for changes to the baseline.
The total adjustment for any given period will be determined with this equation:
Mi = Adj1 + Adj2 + … Adjn
Where:
Adj1, Adj2 and Adjn are all of the adjustments determined to be necessary for the guarantee
period. The sign of the adjustment will be positive when the change will cause an increase in
energy and the sign of the adjustment will be negative when the change will cause a decrease
in energy. Willdan will provide an explanation of the derivation of these adjustments to Customer.
28. Adjustments Reporting and Approval:
For Adjustments presented, the following procedure shall be followed:
a. Customer will notify Willdan of planned changes in building use or function.
b. Willdan and Customer will review the changes planned and determine if these changes are
likely to cause a change in energy use.
c. For changes to existing buildings that are metered, a linear regression will be performed to
correlate heating- and cooling-degree days to the pre-change period’s energy usage for the
622
| Appendix E – Measurement & Verification Plan| Page 170
building, similar to the procedure performed to adjust the base year for weather. The post-
change heating- and cooling-degree days will then be applied to the pre-change regression
equation to determine what the post-change period’s use would have been if no change had
occurred. The difference between this use and the period’s actual use will be, whether positive
or negative, used as the adjustment, shown as term “M” in the equations in the Measurement
and Adjustments Methodology section in this Schedule.
d. If entire effect of the change is independently sub-metered, such as the addition of a building
on an existing utility service, the sub-metered energy use for that building for each guarantee
period will be used to determine the baseline adjustment, shown as term “M” in the equations
in the Measurement and Adjustments Methodology section in this Schedule.
e. If the method for determining adjustment described in the previous paragraph is agreed to be
not appropriate or too complex for a specific adjustment by the Customer and Willdan,
Customer and Willdan will develop a separate measurement and verification (M&V) plan to
track the effect of the building change.
f. If the changes occur at a time when the impact would affect a fraction of that year’s energy
use for an existing building or system, the procedure described in the previous section will be
performed separately for the year in which the change occurred and the subsequent year to
accurately account for the effect of the change in both years. The subsequent year’s
adjustment will then be used for all future years.
POST-INSTALLATION M&V ACTIVITIES
Performance period M&V activities will include energy savings tracking and reporting for a period no
more than 18 months following substantial completion of measures relevant to the Option C guarantee.
During this 18-month period, Willdan shall provide to Customer a savings report identifying the Actual
Energy Savings achieved during the installation period as well as a period of 12 consecutive months
during this period following Project Completion. In the event that the Actual Energy Savings is in excess of
the Energy Savings Guarantee, the Energy Savings Guarantee shall be deemed satisfied. No further
tracking shall be conducted by Willdan, nor shall any additional services be performed.
INTENT OF POST-INSTALLATION M&V ACTIVITIES:
The intent of the Performance Period verification activities is to quantify energy savings achieved at the
meter level, ensuring that the ECMs installed by Willdan is performing as specified in the final energy
agreement.
VARIABLES AFFECTING POST-INSTALLATION ENERGY:
Any energy consuming device and any system connected to a guaranteed energy meter affect energy
use during the Performance Period. These Performance Period performance factors include, but are not
limited to, weather, type and efficiency of equipment in use, equipment capacity, equipment quantity,
equipment utilization, building’s physical construction, building utilization, and HVAC system operating
parameters.
POST-INSTALLATION DATA TO BE COLLECTED:
Monthly utility data will be collected from the utility provider as facilitated by the owner.
WITNESSING OF PERFORMANCE PERIOD MEASUREMENTS:
623
| Appendix E – Measurement & Verification Plan| Page 171
Regular post installation measurements will be taken directly from utility bills based on utility meters and
obtained from weather station data; therefore, no regular post-installation measurements will be
required. In the event that post-installation period measurements are needed for the purpose of
calculating a baseline adjustment, Dublin staff are encouraged to participate in this measurement.
POST-INSTALLATION DATA ANALYSIS:
The Post-Installation calculations will be updated to reflect the results of the Commissioning and Post-
Installation M&V effort. These calculations will determine actual savings achieved relative to the
guarantee.
PERFORMANCE PERIOD VERIFICATION ACTIVITIES:
The First Year M&V Report will be provided between within 60 days of the end of the 12- to 18-month
Period. M&V Reports will contain savings summary and details on proposed baseline adjustments.
M&V REPORTING
Willdan will provide an annual M&V report at least one year following project completion. The Annual
M&V Report will be provided within 60 days of the end of the 12-month performance period. M&V reports
will contain the savings associated with this M&V plan.
VARIABLES AFFECTING PERFORMANCE PERIOD ENERGY USE AND SAVINGS
Any energy consuming device and any system connected to a guaranteed energy meter affect energy
use during the Performance Period. These Performance Period performance factors include, but are not
limited to, weather, type and efficiency of equipment in use, equipment capacity, equipment quantity,
equipment utilization, building’s physical construction, building utilization, and HVAC system operating
parameters.
