The Authority is governed by a Board of Directors made up of elected officials, primarily mayors and city council members, appointed by each member agency. Funding is derived solely from waste disposal and waste import mitigation fees collected at the Altamont, Tri-Cities, and Vasco Road landfill sites. The agency receives no general tax funds. Together with its specialized arm - the Alameda County Source Reduction and Recyding Board - the Authority offers a wide range of programs in the areas of public education, green building. recycled product procurement, waste reduction, market development and technical assistance.

To demyô;tify the process and move forward with your construction project, it is helpful to think of green building as the convergence of three fundamental objectives: Conserve natural resources 2 Increase energy efficiency 3 Improve indoor air quality H d:':;¡·I'n I !'-:':::~~~.: ¡)Ufi;; e C()::~~¡,f.I~'I",'j:t ï~i: ~~ Conventional building practices COnsume large quantities of wood, plastic, cardboard, paper, water and ather natural resources that lead -, unnecessarily - to their depletion. ~ ~ ~ o ~ ~ ~ ,,' ~ ~ ti For example, wood is one of the most COmmOn building materials. but is often used wastefully. We have already harvested 95% of the nation's old- growth forests - a trend that simply cannot continue. Engineered lumber products such as wood I-joists. woad fiber laminates and oriented strand board. utilize fast growing farm trees as an alternative to old-growth forests. These products çan use as little as 50% of the wood fiber to perform the Same structural functions and are typically stronger, straighter and lighter than solid-sawn lumber. :.~; L w W .":: ~ Remodelers have a rapidly expanding range of green building materials from which to choose, Recycled-content decking, insulation. reclaimed lumber and other products divert waste from landfills, while providing quality and durability that often exceed conventional materials. For example, decking material made out of recycled plastic resins mixed with wood waste fibers can last up to five times longer than wood decks, and never need to be treated or painted. Water conservation is another important issue. Wise water usage reduces the strain on resources as well as lowers expenses. Today, remodelers can take advantage of a new generation of high- efficiency washers, dishwashers, and landscape water management systems. The San rrancisco Bay Area chapter of the National Association of the Remodeling Industry (SFBA NARI), In coordination with the Alameda County Waste Management Authority, offers a comprehensive certification class for California licensed building professionals. The class consists of a four session çourse on how to apply green building methods and materials in remodeling. Consumers can locate a Certified Green Building Professional at www.sfbanarl.com. Building professionals interested in becoming certified can contact NAR I at 415-982-9200 or visit their website at www.sfbanari.com. ::1":: .':":¡i ;¡:Jhf;:jH!':';'" Energy efficiency is a cornerstone of any green building project Generation and use of energy ",e major contributors to air pollution and global climate change. Improving energy efficiency and using renewable energy sources are effeçtive ways to improve air quality and reduce the impacts of global warming. Improving energy efficiency is also an economi- cally effective choice for consu mers. Lowering utility expenses allows residents to enjoy the financial benefits year after year. The first step to increase energy efficiency is to add insulation and weather stripping wherever possible, install double-glazed/low·E windows and upgrade to high-efficiency appliances. Other energy upgrades/choices include installing soiar water heaters, photovoltaic pan'els, and purchasing "green power" generated from renewable SOurces like the sun, wind and biomass (when available). I f.ii} ;:;ï:::~' /,::1' The United States Environmental Protection Agency (EPA) reports that the air in new homes can be ten times more polluted than outdoor air. According to the New England Journal of Medicine, 40% of chil- dren will develop respiratory disease, in part, due to the chemicals in their homes. Poor indoor air quality is caused by the offgassing of chemicsls found in many building materials as well as mold and mildew that build up in homes due to poorly designed and maintained heating and cooling systems. One of the most common indoor pollutants is formaldehyde, a suspected human carcinogen. Kitchen cabinets, countertops, shelving and furniture are typically rnode from particleboard held together by formaldehyde-based adhesives. The formaldehyde is released into the home for years after tbese products have been installed. Many paints and floor finishes also contain unhealthy volatile organic compounds (VOC,). That "new house smeli" is actually the odor of these volatile compounds offgassing and Is a telltale sign that there are harmful chemicals In the indoor environment. The building products industry has responded to these indoor pollution problems by developing alternative paint, finish, and adhesive products. For example, solvent-free adhesives used in flooring and countertops can eliminate many of the suspected and known human carcinogens. Paints, varnishes, and cleaners that don't utilize volatile compounds are now commonly available from most major manufacturers at costs compa- rable to conventional products. In addition to the growing number of readily available and cost-effective green materials - an increasing number of builders and remodelers are also using natural building materials such as straw·bale, rammed earth, adobe and cob. While less common in their use, natural building products have a positive impact on the environment as they are renewable and abundant, energy-efficient in production, transport and use; non-poliuting; durable and long lasting. - i c ~ ~ õ z co ~ 1"1 1'1'. ~ ~ ~ 7 " C, C \';) CO C .;~ e, ø nfl C' ::>:1 T (~ ~ 111 "' ~ ~ Q \:'!

These include a concern for the environment, an interest in building more efficiently, health considerations or a desire to create an environmentally friendly image for your business. By applying a sustainable perspective to design, construction and remodeling, green building brings the benefits of resource conservation, energy savings and healthy living. Each of the features listed in these Green Building Guidelines benefit the environment by addressing one or more of the following: resource conservation, energy efficiency, indoor air quality, The following is a list of green building features that convey the benefits of building green: ~:;O~¡!'!1:1 Pq)I.hJGj::{:: ~ :¡ '" ð o ~ -" ., W. 1; r, ~ 12 ø I.L,I " =, w /.:.. :-::1 ¡ ~¡ ~~ 9 Most green building products and materials were developed to do something better than their conven- tional counterpart.

When radiant energy from the sun strikes the roof surface, it is converted to heat energy which radiates downward into the attic and the adjoining rooms. A radiant barrier reflects or blocks radiant heat and does not emit it to the cooler surfaces around it. Radia"t barrier sheathing is a roof sheathing material with a reflective layer (film or foil) applied to the under- side of the 058. Another radiant barrier application is reflective film or foil that attaches to the rafters, reflects radiant heat upwards and doe$ not emit it downward towards the attic and the home's interior. Appl¡c<Jtiðn: Radiant barrier sheathing can be u$ed in place of conventional roof sheathing or apply reflective material (foil or paint) to the underside of rafters and decking. B~l1efit: Radiant barriers reduce heat build-up in attic spaces by not re-radiating heat from the roof to the attic and eventually to the ìnterìor rooms. They can prevent up to 97% of tile sun's radiant heat from entering the home and can bring attic temperatures down a$ much a$ 30 degrees on hot days, keeping the whole home cooler and reducing energy cons.umption for air condítioning~ - " ~ ~ m " ~ " ,.

Unlike vinyl, linoleum does not contain petroleum-based products or chlorinated chemicals such as PVC, which may be a source of VOC offgassing. There is also concern of byproducts such as cancer causing d ¡axins, which may be produced during the manufac- turing of vinyl. ~-'_.~~~..,-,..'_.~"~--~",.~~,~ A¡JplitCitiön: Use natural linoleum in place of vinyl flooring. ,"~~_'~.~""_'W.M~.,"_~"'. Berlefit: Lìnoleum is low-toxic, easy to repair. durable, and stain resistant. Linoleum can last up to 40 years whereas vinyl lasts typically 7-10 years. Dust, dirt-borne contaminants, and chemicals such as fertilizer and pesticides are tracked into the house on shoes. Using a doormat, or preferably leaving shoes at the door, reduces this source of toxic contaminants. A doormat is an easy and inexpensive method to reduce toxic materials that would otherwise be brought into the home. ,·,·,,·,,·,,"'''''.LI\,'' \""."'",',¡::,\"\I\,:\<,,','.,, , IngrEJdi~nb 01 Nc.lt.uté:ll LllÌÖleutn " t o :~ , ~ , ~\ ¡: ;¡ " , ~ o i, Ui:~;~.J C¡,;~ :1i';',:t':¡lt~] i.'ì ~ì Fir:::::i(1:;F~d i:" k~¡;¡,1 .,~~ 1;; ¡'t:::¡:"t?;¡1 HI.:: "..\''::,: I"~ ,'!:::L::Hi::E)::~,¡ De~Gfipï.i~·:~·~'·~~-'~~~~ D,,;~~~";pti;;~-;~·~·~~,..~·_·..,~·_~·_,_· For slab-an-grade additions, the concrete can be polished, finished with expan5.ion joints in various patterns or stained with pigments to make an attractive finish floor.

J :;¡ <;: " ~ " ~ ~ ¡¡ 5 Across the country, in response to buyer demand, homebuilders are constructing homes !!' a that are more energy-efficient healthier and more durable - better known as "green i building." Builders are changing the way they design and build, while er}joying increased II! /;i market share and faster sales. ~ About Green Building Green building is a whole systems approach to the design, construction and operation of bulldings- from the early stages of development through the final finishes in the home. This approach benefits both builders and home<>Nners by reducing resource consumption and improving livability, ô [; ~ 8 ," ~ ô ~ . w Green building benefits are spread throughout the systems and features of the home. Green buildings use reçycled·content building materials, consume less energy and water, have better indoor air quality and use less wood fiber than conventional homes. Green homes reduce potentially carcinogenic volatile organic compounds and formaldehyde from the interior, and construction waste is often recycled and remanufactured into other building products. In response to growing interest in green building, a variety of public and private entities, including homebuilder associations and state and local governments, are creating partnerships to help build and sell green homes and communities, These efforts help market the benefits of green building and recognize builders who are constructing healthier, more durable homes, Homebf'yers increasingly see the added value in a green home. For some, it's energy savings and lower utility bills, For others, it's saving old· growth forests. For still others, it's knowing that their home is a healthier place for their children. These Green BI.1i1ding Gl.1idelines were developed to bring technical and marketing expertise to Alameda County builders, The Guldeilnes are the result of a collaboration among developers, builders, purchasing agents, sales staff, architects, building officials, green building experts, and staff of the Alameda County Waste Management Authority and Recycling Board. The expertise of these diverse stakeholders is reflected through a focus on practices and approaches that are most relevant to Alameda County. ~ ~ ~ g ;:;; ~ ~ z ~ ~ m ~ w w ~ '.' Every builder struggles for market differentiation. Building green is a practic~1 way to address issues buyers really care about. A green building dimension to your business adds a strong selling point. Building green is good for both the economy and the environment. Green building is applied common sen5e, To demystify the process and move forward with your construction prQject, it is helpful to think of green building as the convergence of three fundamental objectives: 1 Conselve natura I resources 2 Increase energy efficiency 3 Improve indoor air quality Natural Resource Conservation Conventional building practices consume large quantities of wood, plastic. cardboard, paper. water and other natural resources that lead - unnecessarily - to their depletion, For example, wood is one of the most common building materials, but is often used wastefully. We have already harvested 95% of the nation's old-growth forests - a trend that simply cannot continue. Engineered lumber products such as wood I·Joists, wood fiber laminates and oriented strand board, utilize fast growing farm trees as an a Iternative to oid-growth forests. These products can use as little as 50% of the wood fiber to perform the same structural functions and are typically stronger, straighter and iighter than solid-sawn lumber, Builders have a rapidly expanding range of green building materials from which to choose, Recycled- content decking, reclaimed lumber and other products divert waste from landfills, while providing quality and durability that often exceed conventional materials, For example, decking material made out of recycled plastic resins mixed with wood waste fibers can last up to five times longer than wood decks, and never need to be treated or painted, Water conservation is another important issue. Wise water usage reduces the strain on resources while lowering expenses. Today, builders can take advantage of a new generation of high-efficiency appliances and landscape water management systems. Energy Efficiency Energy efficiency is a cornerstone of any green building prQ)ect. Generation and use of energy are m¡¡jor contributors to air pollution and global climate change. Improving energy efficiency and using renewable energy sourCeS are effective ways to reduce the potential of energy supply interruptions, improve air qual ity, and reduce the impacts of global warming. Improving energy efficiency is also an economically effective choice for consumerS, Lowering utility expenses allows homeowners to el}joy the financial benefits year after year, The first steps to increase energy efficiency are to add insulation wherever possible, install double. glazedllow-E windows and upgrade to high-efficiency appliances, Other energy upgrades inciude installing solar water heaters and photovoltaic panels. ~ ~ !E " '" ~ '" ~ <; ¡¡ ~ ~I'I Z rn ~ fiJ ~ o " ,~ s '" m ~ c: ~ Ii; " Ii ~ ê û; . ~ "- r: " " '" Indoor Air Quality ~ " ~ " " ~ ffi ~ ~ I The United States Environmental Protection Agency (EPA) reports that the air in new homes can be ten times more polluted than outdoor air. According to the New England Journal of Medicine, 40% of children will develop respiratory disease, in part, due to the chemicals in their homes. Poor indoor a,ir quality is caused by the offgassing of chemicals found in many building materials as well as mold and mildew that build up in poorly designed and maintained heating and cooling systems, i':i 6 ~ ~ ,-' !(:! 8 ~ 0> z ð z One of the most common indoor pollutants Is formaldehyde, a suspected human carcinogen, Kitchen cabinets, CQuntertops, shelving and furniture are typically made from particleboard held together by formaldehyde-based adhesives, The formaldehyde is released into the home for years after these products have been installed. Many paints and floor finishes also contain unhealthy volatile organic compounds (VOCs). That "new house smell" is actually the odor of these volatile compounds offgassing and isa telltale sign that there are harmful chemicals in the indoor environment. ~ o ", ~ w o :5 '-' ~ ~ g 5 ~ z W ~ " ~J$if1g ~olvent-Ftee AdheSi!ves The building products industry has responded to these indoor pollution problems by developing alternative paint, finish, and adhesive products, For example, solvent-free adhesives used in flooring and countertops can eliminate many of the suspected and known human carcinogens. Paints, varnishes, and cieaners that contain less volatile compounds are now commonly available from most m'1ior manufacturers at costs comparable to conventional products, ',:: ,:"":::,:>:,:. ."',':'. >:.

These include a concern for the environment, an interest in building more efficiently, health considerations or a desire to create an environmentally friendly image for your business, By applying a sustainable perspective to design, construction and remodeling, green building brings the benefits of resource conservation, energy savings and healthy living. Each of the features listed In these Green Building Guidelines benefits the environment tJy addressing: resOurce conservation, energy efficiency Or indoor air quality, Cost Considerations In the Survey, consumers were asked if they were willing to pay for green options, and If so, how much, Responses were: 2000 2001 Buyer.;' Willingness (0 Þay Extra For Green Features X!!::;'f::::'\!',:~"?,:,, 9 5% $10, 000 'mll~Ullilwllilll!i!nll¡¡¡1119s% :¡:i:);;:::::':,:¡ì¡;;:::';¡:¡!;::::;:::,:,~::::i,:::::;¡;i::::':,:,>i¡:.!:.';i; 27.6% $5000 ¡llII'!JllJ!llm¡I¡!llwj¡j®!ill¡iIIWIlll[~lilll¡¡iImIII135.9% ,¡,:;:':<:. ~;:;:!'i\;::':, !:~:":,?:: ':1::":':':,:')::'.:'..:::,:) :>,',/': :::.

Willing to Pay The above results are also reflected in an East Bay Area survey conducted in 2002 by American Lives, Inc. of selected new homebuyers, Approximately 70% of the respondents indicate that It Is essential Or very important for new home communities to be developed with green/energy efficient materials and techniques Approximately 50% of respondents would pay $25-$124 or more In added monthly mortgage payments for a low energy home equating to $4,000 to 27,000 higher on the purchase price (at 7% interest rate) While green building and its environmental benefits are becoming more mainstream, it is commonly assumed that green building features and products translate into additional costs. What is often overlooked Is the added value that green building contributes to the home; energy efficiency, improved indoor air quality, healthier homes for the family, and durability. These Guidelines recommend methods and materials that rang(' in cost - some of them cost no more or even less than conventional options. When green building is designed into the project from the beginning it need not cost more than conventional methods, Often, the homeowner and builder focus on the "up·front" costs (materials and installation) to incorporate green features into a home. When other factors are considered, such as lower maintenance and operation costs, many of the recommended strategies in these Guidel ines offer tangible economic benefits to the homeowner. Energy upgrades alone usually result in a payback through lower monthly energy costs. When considering green building measures, it is very important to balance product and installation costs with other significant benefits such as energy savings, increased durability, enhanced air quality and healthier homes. ~ !! !:! ¡;¡ ~ i'Ii m " ~ ~ ~ -.

Home buyers speak their own language, and understand and embrace green building only when It is explained in their tenns, Energy efficiency, improved indoor air quality, water conservation and saving old·growth forests are terms that may have different meanings to different buyers, All these things together mean a new home that offers more value and a more comfortable and healthier living environment. Knowing about the benefits of resource-efficient construction is one thing: spending money for those same features is quite another. According to the Survey, consumers were asked to choose their three most important upgrades when buying a new home.

When Consumers think about a new home, they think about what it offers them, not necessarily what It does for the environment. Quality always rates highest next to location when buyers buy new homes. Green homes offer higher quality since most products were developed to perform better than the conventional products they replace. The Guidelines and accompanying resources will assist you in developing and implementing green building packages into your building pJ'Qjects. What makes a home truly green is a combination of all of the features listed in the Guidelines. In this way, the home combines the collected benefits of resource conservation. energy efficiency and good indoor air quality. Offering segregated packages is a starti ng point to help clarify what your market is most interested in, so you can make the most appropriate incremental steps toward a trUly green home. PlêaS¡Jnl.

Below are samples of the types of "Green Building Packages" that could be developed to respond to consumer demands for green homes, ~ w ffi ~ ~ iii ~ ~ ~ Natural Resource Package Natural resource conservation is becoming mOle important to buyers every year. Saving forests for camping, fishing and hiking is a value that families hold for their cI1i1dren's future, Conserving resources today by incorporating green alternatives is a great way to get your buyer's attention. Using recycled content products in your homes "closes the loop" for families that are committed to recycling.

Energy Efficiency Package Energy upgrades are one of the first things that Consumers would pay metra for - $2,300 on average - if they could expect to see a payback through lower monthly energy costs in four years. According to the Survey, only 2% of the homebuyers said they would mt be willing to pay more in up-front costs for energy efficiency upgrades that would reduce monthly utility bills, 83% said that insulation should be above code and 90% or higher efficiency furnace should be standard features in new homes. Consider offering the following as part of an Energy Efficiency Package: Low-E windows High efficiency (90% or higher), sealed combustion furnace and hot water heater High SEER/EER air conditioning units Fluorescent light bulbs Advanced sealing and caulking to reduce drafts 2x6 wall framing with increased insulation Insulated foundation Indoor Air Quality Package While energy efficlen<;y is at the top of the consumer list Improved indoor air quality is also a priority for hornebuyers. Alrrost nine in ten respondents of the Survey are aware of products that emit gas chemicals into their living envimnments, 75% or those people say it's extremely or very important to live in a home free of toxic chemicals.

The combination of green products and practices you choose creates a "story" of how your homes protect the environment reduce air pollution, conserve natural resources and save money. To be a successful green builder, train your sales staff to tell the stories behind the products. Even If the story isjust a list of benefits, you leave a lasting impression on your buyers. Market Differentiation While green features don't always sell the home at first blush, they make buyers think and will often bring them back. Emphasize that green doesn't necessarily cost more and can often save money in the long run, Buyers are becoming very sophisticated as publications like Better Homes and Gardens, Redbook, Family Circle, Sunset, and home improvement magazines feature more green building stories and products. Marketing green provides unique opportunities. By distinguishing your company from other bullderô, you can step into a new arena of recognition. By thinking outside of the traditional marketing box you can engage the public, Even in a seller's market where homes are soid before they are finished, building green creates a lasting image for the company, Your homes draw public curiosity and interest. and your story is attractive to the news and trade media. People start to identify you as the builder who cares, which engenders loyaity a nd creates referra Is, Educate Your Sales Slaff Sales are everything, It doesn't matter how well built or how green the house is If your sales staff doesn't communicate the value of building green to your customers, Your sales staff are your greatest advocates - take the time to train them about green features and benefits, If they feel confident. and understand that building green adds value to their customers, they will have the tools to close a sale that might otherwise get away. Convey the Benefits It is important to complement green option packages with a marketing program that clearly identifies the benefits, Concepts such as energy efficiency, indoor air quality, and resource conservation, while easy to describe, do not necessarily address homeowner concerns, One way to address this is to sort the features in terms that are important to the buyer. Use the Green Buliding l3eneflts as a tool to assist you in creating marketing materials that address green building features. Each green feature is discussed in detail in Chapter 4.

Creating green multifamily housing i5n't about i:lltruisr'n. It isn't about doing good or feeling groovy. And it isn't about adding a few bells and whistles to . proposal so that it will pass muster with funders, community leaders Dr buildin~ officials. Green building is about improving our design and con5tructiorl practices so that the multifamily homes we build today will last longer, cost less tQ operate. ar1d won't harm the health of workers and r.,idents. It is also about protecting natural resourçes Çlnd improving the built environment so that ecosystern5, people, enterprise's and communities can thrive and prosper. Green building represents a paradigm shift-a crucíal change in the way we understand, desigrl and build Ilousing in today's world. It doesn't happen by accident·nit requires thurough planning, tl10Ughtful design and quality construction, With the budget and time pre55ures we're all under today, is it really worth the extra effort? We think it is. Green hou,ing is good for people, good for Bay Area communities, and good for the natural environment. Better buildings! it turns out. are also better for business. Developers, designers and other building professionals who follow "building a5 u5ual" practice' may find thom5elve. at a competitive disadvantage as regulatory and market forces shift the indlJstry toward built environments that are healthier, more resource efficient and less polhJting. / Cornrnolì roolìl!:'.. !)(Jch a~ thi!'; hlJilrling At MurPhy ~~1fICIi in San JO$ú. <'Ire an intep,r.;¡1 põut of multifcHllily IIVl1Ig.

TI1e Guidelines are the re5ult·of collaboration among developers, architects, builders, building officials, green building expert" and staff of the Alameda County Waste Management Authority and Recycling Board. The expertise of the,. diverse stakeholders is reflected through a focus on practices and approach.. Ihat are most relevant to affordable and market-rate multifamily housing in Alameda County, The measures in,these GLJjdeline~ range from basic! commonsense recommendations such as designing entrywaY5 so that fewer contaminants are tr.cked in on people's shoes. to Installing sophisticated renewable energy generation systems on Site, No matter where you are on the green building 5pedrum-from novice to expert-you will find resources, de5ign ideas, product illforma.tion, çase studie~ and real-world advice that you can put to use today. If you or your organization has not yet embraced green building, these Multifamily Green BUilding Guidelìnes,-..,,·as well as marlY other resources uffered by ACWMA-will provide you with a solid foundation ,for getting started, You will find many uf the measures to be quite easy to incorporate into projects immediately. Other measure5 that require more effort can be added to your practice as you gain experience and build support for green design within YO~Jr mg~nizatiùn. If you are experienced with developing high-quality multifamily housing, some of the approaches and products recommended here may already be part of your daily practice, In that case, tilese Guidelines will help you employ more advanced green-building strategies that wi II reinforce your organízation's .!e~dership po~itiDn_ Z -1 :::0 o o c n -1 o Z IN1RODUCTION ------------------------. ----------- PAGE 1 ----,-----,. z --- ::::0 o o c o --- o z -------------------------------------. These Guidelines can be IJsed in different. ways deperlding on your role in the ,multifamily housíng development proc.es5. H~re tlre 50m~ considemtions: » Policymakers. Read the introduction tQ eacll section for an overview of green building for multifamliy houSing. Then read througll tile measures in tile Planning & Design section. These are particularly relevant because they include policy recorT1f[H:~ndC:lLions you can adopL before a projetL is even propm¡ed. » Developers. Use these Guidelines as c1 way to organize your teat"Q's i3pprotlch to green b~Jilding: the Guidelines will help pwvide your' team wltll a common language for discussing alternative design. Heference the Guidelines in your RFQs <1nd RFPs for architects, and use it as d discussion guide throughout de5ign. The t"ble on page 7 provides a useful timeline tor when to tocus on particular design strategies. Property managers should read the Operations & Maintenance section caretully tor ideas on minimizing operating costs. Architects. Treat these GuidelinEs as both an idea bODk and a reference nlanual. When beginning a new project, Sc.an the list of measure5 in the Green Building Timetable on page 6 for ideas that might be appropriate for your project. Within each measure, use the graphic guides and tt1e Description and Benefits Information to help spark the creative process.

Green building is a whoie-systems approach to the design. construction and operation ôf buildlngs-trom the early stages of developlnent through the tlnal tlnishes, This approach benetits building industry protessionals, residents and communities by improving construction quality! increasing building longevity, reducing utility and maintenance t05ts, and enhancing com tort and livability. There's nothing mysterious about green building-it's really just applied com- monsense. To move fOIWard with greening your CQn5truction project, it is helpful to think at green building as the convergence at three tundamental objectives, 1. Conserve natural resources 2.lncreii3se energy efficiency 3, Improve indoor air quality I'A(.;~. 2 -------------------------------------------------------------------- ACWMA MULTIFAMILY GREEN BUIL.,DlNQ GUIDELINES April :!(J()4 INTRODUCTION Z -I :::0 J o o -I o :7 ._---------------------------------~------------------- -'------- , [" .,' ,\ ¡ r 1'1. I,·,', u NATURAL RESOURCES CONSERVATION Conventional building construction and operation needlessly consume large quantities of wood, water, metal, fuel and other natural re50urce5. Wood! for example, is one of the most common buildjngmaterials, but it is often lJsed wastefully, Fortunately, advanced framing techniques have been developed that can substantially reduce lumber requirements. And using engineered lumber and wood products certified by Ihe Forest Stewardship Council can help prolect old-growth forests. In fact, fhere are a great variety of effective building strategies that conserve natural resources, as well as providing benefit5 such as cost savings. One approach is to avoid using unnecessary materials, such as by allowing structural elements like conerete floors to serve as finish materials. Other strategies include using durable products fa reduçe wi'ste and specifying recycled-content prQduCIS Ihat reuse natural resources, ENERGY EFfiCIENCY E.nergy efficiency is the cornr?rstone of any green building project. Improving energy efficiency and using renewable energy sources are eff£çtiv~ ways to reduce fhe potential of energy .upply interruptions, improve air quality ¡:!nd reduce the impacts of global warming. Improving energy efficiency also makes economic sense for building owners and residents: an energy-efficient building saves mOlley by reducing utility bilis year after year, INDOOR AIR QUALITY Poor indoor air quality is often caused by mold and mildew that build up as a result of moisture infiltration or poorly designed and maintained heating and cooling systems. Dust, another mi,'3jor source of indoor air pollution, can be reduced by uSing track-off floor mats at entryways, and by using easily cleanable fk)Qring materials such as natural linoleum, wood or wood alternatives, or concrete. Another common source of indoor air pollution is the offgassing of chemicals found in ,"any building materials. Pressed- wood products such as particleboard and plywood paneling. for example, are typically held fogether by adhesives that release formaldehyde-,·a probable hUrTi1:ln u:lrcinogen-into the home for years after installation. Many paints, floor finishes, adheSives and sealanfs also emit unhealthy volatile organic compounds (VOC,), Fortunately, the building producfs industry is responding to these indoor air pollution problems by developing saler products, including alternative glu." in pre5Sedwuod products, and low-VOC paint, finish and adl1esive products. (..! '.' ~ n ~~:~, ! ("'¡ ~:':.:.) l' <: ';, i: :; ;. j \,.' Too often, design and building disciplines remain highly fragmented, developers and fundets select (or are given) a site; architects design the building, mechanical and electrical engineers design HVAC and lighting; and so on. It is rare, for instançe, to involve the mechanical engineer in architectural decisions, even though those decisions might significantly affect equipment costs and energy use. .-.-----------------. ..--------------, ---------------------- INTRODUCTION ACWMA MULTIFAMILY GREEN BUilDING GUIDEI.INES I\[JIII ;1()()4 Z --I :::0 o o c o --I o Z r'AGE 3 --------------------------------------------- ..,--'--'----'-----'-------- z -j ::::0 o o c o -j o z To minimize the cost and maximize the benefits of green building, use an integrated de5igrl precess that involves people who represent these perspectives, » Owner ~"io Occupant (may be represented by an experienced property manßger) " Arch iteet ."

"",..1 .",_.1 While tile 11ealth and environmental benefits of grc,," building are well established, many people still assume that green building costs more, But taking an integrated approaclì to design can actually reduce construction and operating co~ts. At ä t:ertain critical point., it's possible to achieve signifìcant cost savings compared to ~tandard practice if ìntegratcd dcsìgn is used. A contractor! for examplet can be engaged early in design to help steer t.he desigr¡ away from expensive solutions and toward cost..effective ones. The options available during ~chernatic design can easily include strategies suell as simplifying a building's wall structure by changing the wall articulätion to äilat: wall with bolted-on overhangs and thick trim. Such à change can often save money and a lot of wood, but would be costly to do once construction documents were underway. Just as the contractor can help the design team tind cost-etfective green solutions, so Can the other team rm:rnbers. The mechär1ical engineer may be able to recommend increasing the exterior wall thickness to accommodi3te more insulation, which could result in reducing the size and cost of the beating system. If the developer is concerned with achieving HLJD noise ratings and is part of this conversation, she may ask the engineer whether using special sound-rated windows will also help reduce cooiing needs, - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - PAGE 4 INTRODUCTION ACWMA MUlTIFAMilY GREEN BUILDING GUIDElINE:S April 2004 -..---. .------------------------------------------- These collaborative discussion5 are pDwt:rful, but thE range of cost effective solutions narrows as the design progresses. Consider daylighting, for example, During 5therrla!ic design, dayllghting can be achieved by moving the glazing to the north and south walls and correspondingly adjusting the intérior spaces. The cost at this change is close to zero. If daylighting gQal, aren't r'l5ed until 111e design development phase, it may be possible to provide daylighting by changing the heights of windows and the depth of roof eaves, for a moderate cost inçrease, But if daylighting goals aren't raised until the construction document phase, daylighting might have tQ be achieved hy ,electing high- end glazing and installing light shelves, for a considerable cost increase. For every recommendation in these Guidelines, we h¡:¡ve carefully weighed the measure's cost against its benefits to justify its inclusion. While not all me'"Jre, will be applicable to your project, we feel that the measures included are relevant and reasonahle for multifarrlily developments built today, Som~ of the recommended rT1easureS do cost more initially, but this additional cost needs to be evaluated in the context of the IOtlger-lerm benefits provided; utility cost savings, better indoor air quality for residents, healthier joh,ite' for workers, and I~Jnger building life. When considering green building measures, it ís very important tö balance upfront. desigrl, product and construction costs willl these other significant benefits (this process of evaluating the Inng"terr" CDSts of design decisions is often referred to as '1Iîfecycle cost analysis"), r·unding affordable hOU5ing involves unique challenges and opportunities! particularly if the design includes green building measures that may cost more upfront but provide long-term benetits, For good information about funding affordable, green multifamily buildings in the San Francisco Bay Area, refer to TIJe Materials Nandbook: Guidelines for Affordable Sustainable Nousing. published by the San Francisco Mayor's Office of Housing and Asian Neighhorhood Design (available from www.andnetorg). Green building can be seen as pushing the design and construction industry to do thing~ that may be new, such as integrating the design process, New practices sometimes cost money. But green buildings are more than just buildings, They are the end result of ~ çollaboration between people on all levels of design and construction who are committe.d to improving on ye~tt:rday's practices. Tak.ing incrernental ;;t.e¡y; toward tilJliding ¡;;rcen Green design comes in many shades. Many projects are 4jlight green": they include:: a handful of fairly convention81 but effective strategies. such as energy-etflcient lighting or high-efficiency heating. Other projects are "medium green"- they've taken bigger strides toward including high-performance attributes such i::H::; advanced framing or cool roofs. And then tllere are cutting-edge green projects that fully embrace integrated desig" and may even have advanced features such as bUilding-integrated photovoltaics. If you aren't able to take an int.egrated appro;:¡ch to design on your current project, you call still take steps toward creating a healthier and more energy- and resource-efficient building. Inside these Guidelines you'll find many strat.t:gies that are easy to implement and add virtually no cost, such as low-vac paints, sealants and adhesives, recycled-content carpet, and water- efficient tixtures. Your project may not be labeled "green," but you can still include many of these simpler measures, As your team's experience wìth green huilding grows, you'll likely find yourselves scaling up to ever healthier and more effective de5ign and Ç:onstruction practices. ...------------------------------------------ ACWMA MULtiFAMILY GREEN BUILDING GUIDELINES Apn1200<1 INTRODUCfloN z --j ::0 o o c o --j o z ----- rAGE 5 ------------------------------------------------. .. - -.. .- -. ." ,~ -. - - Z -I :::0 o o c o -I o Z Círeì:~n builci!t1S?,tirrlelaIJle The table below allows you to qUickly scan all the measu,es in these Guidelines to get a feel for when each measure becomes a priority during the development process.

CONNECTIONS TO THE NATURAL AND BUILT ENVIRONMENT Fundamental to green design IS the relationship between a building and the environment-both the natural andthe built ~nvironment. While affordable housing projects typically have more ,ite constraints than market-rate housing, every site presents unique opportunities. The design team should carefully assess the site's natural elemenl:;..·,including solar access, wind conditions and existing plant and animal life-and strive to design in harmony with th05€: elernent5 to'reduce energy use, increase livability and prQtect the environment. Planning and design decisions related to the built environment-existing buildings, streets, commercìal develcp'ment, parks, schools and more-are as important as the decisions related to the natural environment. To a$ses~ höw to best take advantage ofthe surroundings, the project te"m may need to do considerable analysis and develop ò nlHTiber of schematic designs. INTEGRATED DESIGN For a project to make a signifiçant diff~rence in terms of economic and environmental SU5!òinòbility, as well as quality of life for building residents and the community at large, it's best to take an integrated approach to de.ign, The recommended Planning &.Design measures pre~ented here are fundamental to integrated design, and should be addressed with as much care, time and resources as the project can bear. Choices made at this stage may affe,ct hundreds of deci$ions later on, For example, if a choice is made-either actively or by default-to not maximize a building's orientation for best 50lar access, that may preclude many green design strategies, from pò$sive ,olar heating to daylighting to eliminating air cond ition ing '(for mDre abDlJt integr<lted design, sr.:.'fJ the Guide/illes' introdHcti(Jn), COMMUNITY SUPPORT An important aspect of green mUltifamily hou.ing is creating conditions tllat foster economic and social well-being in the community, Many of the measures in thi5 section offer tremendous community benefits, ranging from reduced traffic cÓngestion to more attractìvü opportunities for recreation to greater economic vitality. For the developer, engaging municipal representatives and community leaders early in the design process can pave the way to a much more SUCCG5sfIJ! project. CODE ISSUES In some municipalities, density, zoning and other code í55ues may $ometimes conflict with green design strategies, such as infill and mixed-use developments, improved pede:strian and bicyclist access, and elJen certain Bnvíronmentally friendly landscaping practices, Early in the planning proce55, the development team should identify potentialiy problem.tic code issues and work with the appropriate officials to overcome these barriers. -1] ""'-"'~ ; » -:7 ,/ "'-- ,.. ,,,.:::~_.. -''''''~I 4~" ~.. u) Qo ~, ~",." rri ( .') j '--"'¡ ..J " ~-'·.I .,~~. ------------------------------ PLANNII'IIG II,; DESIGN PAGE 3 ~ - - - - - - - - - - - - - - - - - - - - - - - ~ - - ~ - - - ACWMA MULTIFAMILY GREEN BUILDING GUIDELINES April 2004 --------------------------------------------------,- 11 ,- ~.

Infill projects help revitalize older urban areas. For the developer, some of the recommended Planning & Design measures can be done with little Or no extra c.o.t if incorporated early. Providing recycling collection facililies, for example, costs very little and can potentially reduce waste disposai fees for years to come, ,Other measures-such as choosing infíll site~ and creating rnixed~use developrr\ent5-may require additional design time, But cost increases can often be offset or minimized by adopting an integrated design approach (see the Inttvdutrlo/J to tlJese Guidelines).

More than one-tllird moves into th~ soil where organisms break down and naturally filter pollutants before the rainwater reaches groundwater or :5urfar.e waterways. As land is developed with buildings, parking iQts and nther impervious surfaces, two major changes occur; » More 5t~mTlwat~r rUn5 off the site. On developed sites, as much as 70% of all rain and irrigation water flows into waterways (via stann drains) without moving through soil. The soil supports less rnicmbiallife and is Jess able to filter harmful chemicals out of the little water that moves through the soil. Watershed quality decreases rapidly when the tntal impervious area exceeds 10% of a .site. Pollutant load also increases. One acre of parking lot, for example, Gollec:ts as muçh a$ four g¡:jll(]ns of oil, gasoline and diesel fuel each year. When rainwater runs off the parking lot, these pollutants end up In our waterways, Other PQIII,¡tant~ include pesticides, fertilizers, pet waste and suspended sOli particles from poorly vegetated ground. Steps can be taken t.o increase stOrm water retention on site, which reduces runoff and pollutìon (. nd help5 tilter and treat stormwater. The first step is to minimize impervious surfaces through landscaping practices ACWMA MULTIFAMILY GREEN BUILDING GUIDELINES April /[)04 .p - - - - - - - - and using pervious paving, Another step is to design teatures into the site that channel runoff to swales. porous surfaces and holding areas (f'h1t1ninp,& DesiP,lJ: MAFiSIJrP. DB-Landscaping). Another strategy is to install systems that filter and treat storm water as it leaves a site. Benefits Increasing porous surfaces decreases runoff and protects the health of watersheds, creeks, wetlands and other bodies of water. Reducing runoff improves soil healtl1 because it retains vaiuable topsoil onsite. I~ctaìning rainwater on ,site reduces runoff and filters pollutants. Downstream engineering costs may be decreased as wel L Application ... .-.-----....--.-.-- When building on undeveloped sites Igreentieids), design the site. so that storm water rates and quant.ities are not increased from predevelopment levels. Runoff from the development IS either absorbed Or cöptured on site throllgl1 porous paving, bioswales, trenches and pond., With previously developed sites, plan for no net increase in runoff rate and qu¡:¡ntity, or ideally, a net decrease of runoff post-development Storm water treatment in urban areas typically includes proprietary treatment systems beçau~e of limited space far natural filtering and separation. Design petai!!. ,..''''.-..-''-----. Planning fer appropriate stormwater retention and treatment should be done as part of an integrated design proce5S (~p.p. fhp. introduction to these Guidelines). Consider the building location and the surrounding environrnent carefully because they greatly affect stormwater generation (N"lnnin¡:; & DI'!.'iign: Measure 03-Building Placermmi ¿md Ori&{I/üliofl). To lessen stormwater impacts on w'1ter:.h~ds, reduce the flow Irate and quantity of runoff), and provide treatment through filtering and ret.ention. MINIMIZE IMPERVIO,US SURFACES Typical ¡lOusing projects have 25% to 50% ímpcrviQUS slJrfat:es, or more. In most cases, alternative surfaces can be used that allow rainwater to soak in. MarlY porous surface options also reduce tile heat island effect (Plf/!lning ,¡;. Dp.sign: Mp.a5lJrI'! 09-Cml Site). Some recommendations are: » Keep impervious surfaces to a minimum. Use porous $urf<':Jces, including permeable paving, and maximize landscaped areas to encourage infiltration.

For example, a construction IAQ man¡:¡gement plan (Site work.: MSiJSUr9 03), spells out appropriate 5tròtegies for minimizing construction-related IAQ problem$. The plan wi II often specify that porous materials like carpet and furniture should only be installed after finish materials such as paints and sealants have cured, and that carpeting and furniture be a:red out before in5tallation. The plan may also require the contractor to schedule a preoccupancy flush-out of the building's interior to reduce the potential for post-occupancy IAQ problems. SPECIFICATIONS AND CONTRACT DOCUMENTS In the Bidder's section nf the project summary, include the required diversion levels of const,uction and demolition (C&D) waste. Also, include language in the specification Section OJ 505 r~quiring C&D diversion. Contract documents should specifically state the role of each party in the construction waste management and construction indoor air quality (lAQ) management plans, from architect to .ubcontractor. The documents should clearly hold a respon.ible party accountable for failure to meet waste management and pollution prevention goals (~ee the individual measures in tf~is s8c::tion for derails).

With the Bay Area's large number of C&D recycling f;:¡cijities, including mixed recovery facilities, implementing a C&D waste management plan isn't difficult. If the jobsite allows for mUltiple bins, most contractors choose to source-separate materials slIch as concrete, metals i:H1d cardboard, since disposal rates are lower for source-separated materiðl .;¡nd ;¡ome material5, such as metais, can generate revenue. Some contractors find that separating materials requires additional labor. Mixed C&D recovery facilities are increasingly the preferred recycling cl1Oice, especialiy If there are space or time constraints at the jobsito, or if the materials are difficult to separate on site, SUCl1 as demolition materials from tenant improvement projects. Mixed C&D facilities receive, sort and recycle loads of mixed m"terials from construction or demolition sites if 60% or more of the totai load consists of recyclable materials, Recycling rates vary, but most mixed C&D faciliti~5 recycle 50% to 70% of the material delivered.

CONTRACTOR EXPERIENCE Some of the products and techniques described in this sectiQn require experience or specialized skills that aren'tfound Dn every construction crew. For example, the techniques far de5igning and working with high-volume flyash concrete (StfIJdure: MO¿j'.>urO (2) are still new to many engineers and contractors_ Similarly, if installing damp~spray c~lIulose in5ulation (Structure: Mf:iisutt U9), you need an experienc~d subcontractor who knows how to avoid, moisture-related problem,. With steel framing (StruGtute: M!:JiJsur8 U6), a more ski lied labor force i$ u$ui;lIJy needed. As early as possible in the design phase, the project team 5hauld identify any measures that migllt diverge from standard pradice. PRODUCT AVAILABILITY Many of the materials recommended here are readily available. For example, many cities in Alameda County have ordínance$ requiring con5truction site waste recycling, sO there i5 plenty cf recycled aggregate available (Strucw{f:; Mea5Uffl 01). High~volume flyash mixes (Structure: Measuf"-' 02) are also widely available in the Bay Area, as are recycled-content insulation with no,added form¡:¡ldehyde (Structure: MeasureD!)), engineered lumber (Str'uctutf:¡ Me&suff. 04), ~nd high~p1$rformance windows (Struciuro: Mc:!asuftJ 13), Other products. may require more ~ffcrt to obtain. Whi Ie FSC- certified hardwoods (StrlJc.t/Jfp.~ Mea.~IJfe 03), for instance, are generally more readily available,than FSC softwoods, supply fluctuates. which affect, both availability and price, Early in the design phase, the project team should flag any products or materiâl5 that might have longer lead times or requÎre extra effort to source 50 that the contractors can work to ensure that they will be on hand when needed, COST An integrated design approach will help reduce construction costs as well a5 operating costs, Far example, it may be possible to downsize or eliminate the air· condìtioning $ystem if the design includes a cool roof (Structure.. MeastJre 12) combined with other energy-saving features, such as overhangs, incre<3.sed insulation, high- performance windows and proper building orientation. Other measures may 005\ mOre than conventional construction if the product itself is more expensive, the technique ,is more labor,ìntensive, Dr the contractors have limited experience with the technique and therefore submit higher bids, For ex.ample, studies have estimated that, overall, installed steel framing ($trtlcture: Measure 06) costs anywhere from 0% to 7% more than wood framing, mostly because of increased labor costs. However, steel prices are mor~ constant than wood prices, resulting in longer price guarantees from manufacturers, which 11elps with project budgeting, Compared to conventional wood framing, advanced wood framing design (Structure: Measure 05) does 'require some additional effort during de~ign and careful oversight of the framing contractor in the field, But it can reduce lumber use by as much ì;l5 ?O% to 30%, while also providing more room for insulation and increasirlg the building envelope's energy efficiency. Refer to the individual measures for more information about the savings and costs a»oeiated with the structural components of green multifamily housing. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - . .---------------.

It! the United States, about 60 milliDn tons ùf powdered fly",h is removed from the exhaust of these power plants every year to reduce air pollution, Less tllan 30% of that flyash is recycled. Tile rest is landfilled. One common method of recycling fly ash is to use it to replace C;I pc)rtiQn of the portl¿¡nd cement in concrete. Concrete is consists of sand, aggregate, cement and other admixtures. Most existing recommended practices limit flyash usage to 15% or 20% of tile cement portion of concrete, This increases the strength and improves the durabilíty of concrete. But. l;sing a higher volume uf flyash yields greater strength benefits and divert" a larger amount of this waste from landfills, High.volume flyash is tYPically defined as concrote that contains more than 30% flyasll In tile cement portion of i:3 contrete mix.

Desi2n Details Although flya5h ha~ been lJsed in concrete for decades, the technlquos for designing and working with high- volume flyash concrete are still new to many engineers "rid contractors, 50 illS important to discuss flyash early in the design phase. Flyash reaches its rrH:ixirnum strength more slowly than typical mixes, although this can be partially addrcssed by t~~e use of low-water mixes. In some cases, ibis added time can affect con5truction scheduling, so be sure to get this information early from the engineer. A High-volume Ready Mix with bO% flyash should be :nixed with 20% to 25% less water than a product wilh riD flyash. The water quantity is the key to keeping cure time rcasonahle because accelerant admixtures are expensive and not alwaY5 effective.

Engineered lumber is more dimensionally 5table and straighter than conventional lumber because it doe, not have a grain and therefor. does not expand and contract as much as sol id wood. Wuod I-joists use up to 50% less wood fiber to perform the same structural function as similarly sized solid- sawn lumber, and they will not twist, warp or split. They are stronger, lighter and can span greater distances than 2x105 or 2x12s.

DESIGN PROCESS IdEally, green finishes and furnishings should be specified .arly, as part of an integrated design process (see the introduction t{ thf;!se GlJidelines). U is possi ble, however, to make incremental improvements to a conventional building that IS already underway by including 'some"ofthe green finishes ~nd furnishings rneasures described in these Guidelines. For example, if the original design calls for vinyl floor.ing, it may be possible to 'sub5titute natural linoleum (Finish(!!; & 1'/Jfr1ishi/J8S: Measure 06) if there is funding for the added ,cost. Low-VaC paints (Fini.~hes & FurnLshings: Measure 02) can readily be substituted for conventi.Or1al VaC-compliant paints, although the cost may be slightly higher and allowances may need to be made for differences in paint coverage and drying time, AVAILABILITY Green and healthy finishes are now much more readily available than even a few years ago, All major paint manufacturers, for example, make low- or ,'eroNOe paints that meet performance requirements. There are, many 5uppliers of'linoleum (f'¡t¡iSI1eS & Fumi5fring~. Mt'èj$utlJ u6¡ and recycled-cont~nt carpet (Finishes & Furnishings: Mui:!$ure 05), Other product5, while generaldy available, may require more effort to obtain, such as cabinetry with no added formaldehyde (F:/ni:;hGE¡ & Famisl¡!np,SI M~,~fJrn 09). COST It is critical tt1at operations and maintenance .costs be tak~n into account wIlen considering the costs of finishes and furni5hing$. Some conventionai products cost less initially thon environrnen!ôlly pre'ferable optiOns, but are infenor in quality and will require frequent 'and, costly maintenance, 'repair or repl¡:¡cement. Many green finishes and 'f,urnisllings,are cost-co.m'petitive with conventional products and can be Llsedinvirtually any aftordablemultifamily housing project. These indu,de low-VOG paints (Finishes & Furnishings: MfJõ1SUrf:! 02)1 HCFC-free 5e~lar'1ts (Fini.'ihes & Furni:.hings!

Certain materialsr such as recycled ceramic tile (Planning & Design; Measure )4) and bamboo flooring (Fini.~hes & FlJrnishings:,M8i1su(() OJ), may tend to ÇO$t more than conventional products, requiring a special comrnitment from the developer.

In multifamily buildings, there are two opportunities to po,itively affect IAQ through e"tryway design, 111e common entry areas! such as lobbies, hallways, balconies, laundry rooms, community rooms and elevator areas; and tile IlvinE units themselves. The IAO and health implications are greatest in the living units, especially thO$e occupied by cl1ildren and elderly residents. ~iere are strategies for good entryway design: COMMON ENTRANCES ~ Specify a three-component track·off entryway system that consists or 1. A permeable outdoor mat or grille system to collect the dirt and water: 2. Indoor mats that aid in scrubbing shoes; and 3, A smooth-surface, waterproot flooring material that is easily cleaned and will collect any remaining contaminants from footprints (such as tile, stained concrete or laminate prodl)çtsl. These systellls should extend 30 feet into the building af entryways or as close to that length as possible, Avoid carpet at entryways because it is hard to clean and it traps dirt. /;- Avoid using pesticides and other chemic::als near bu il dings (P/¿mrliny & Du:;ign: Me,~6'I.If(~ 08 Li.7f1d;iGfi/.Jinp,).

Description For market-rate multifamily !lousing, there arc now ma.ny alternatives to traditional hardwood flooring, including FSC-certified or reclaimed wood, engineered wood, and rapidly renewable m;:¡terials such as cork and bamboo. SOLID WOOD FLOORING Most high-quality, knot-free wood flooring comes from old-growth trees, which arc not harvested 5ustainably, Finding alternatives to old-growtl1 wood flooring protects fore5ts and ecosystems (f(w inf(Jrmation DI1 SIJ.~t~inahle forPost/}' and /cWj¡'ir!lj¡ ~(:v Slrllt:lw;; MeMUrv (}.j. ($(:·Cf.:r'tifieä WooÔ). Traditional hardwood flooring comes from a huge variety of tree ::;peçies, including oak, cherry, maple, walnul, mahogany and beech, Local flooring sLlppliers now supply FSC-certified wood in tl1ese common species and in tropical ~xotics. ACWMA MULTIFAMILY GREEN BUilDING GUIDELINES i"'\pril 2ü04 Reclaimed wood is another way to have higl1-quality solid wood floors without cutting old-growth trees. Recovered wood comes from sDurCe5 5uch as uld buildings and railroad ties. It can be refinished or left with its natural blem ¡shes (fOr mort about rec/(iime.d mMeri(iI.~, sef! Fini.she.~ & Fumi-,;hing-,;; M1.'i1~·urC 08). ENGINEERED WOOD FLOORING Engineered flooring is a poplJlar alternðtive to sDlid wood, It has a thin layer of hardwood on top of a high- density fiberboard core, The result is the look and feel of solid wood without harvesting old-growth trees, Most engineered flOQring product< can be refinished at least once to extend the:r life. Laminate floors 110ve a 11Ighly durable wear layer applied over a thin veneer Or paper image of wood. The substrate is high-density fiberbnard Qr plywood. Like engineered floors, laminates can "float"; that is, they are not glued or nailed to the floor. Laminates have low first cost and are extremely durable when properly instalied. Prnducts with longer warranties are usually worth the extra cost. RAPIDLY RENEWABLE FLOORING MATERIALS Bamboo and ~()rk ¡¡:Ire rapidly renewable materials known for their durability and beauty. Beth can be harvested wltho<Jt destroying the plant, allowing I.ilem to regenerate and be reharvcstcd in ð relatively ~hort tirT1B period. Cork and bamboo come in solld,and engineered wood ~ystems. Full-grown bamboo stalks are cut lengthwise into narrow strips. The manuf"c:turer giues these together to form flooring, plywood, paneling and other products. They ôr~ glued either horizontally in layers. or vertically in strips. Cork is semi-malleable and absorbs shock and abuse, Cork is lhe ouler bark of the cork oak tree, Tile tree is stripped of bark every 8 to 10 years, but survives to be harvested again and aga.in.

Numerous organizations in the Bay Area acçept reçl<'.lirned, overstock, old stock or misordered materials to be resold. Other companiEs will 5trip buildings of reusable components prior to demolition. Common salvaged materials include timber, doorsl sinks, fencing, bricks, tile, pipes, hardware and light fixture5. Reclaimed lumber is among the most widely available prr>d~Jcts, as studs, be:ams, flooring 8nd trim. Finding salvaged materials, cspeciiJlly for liJrge projects, can be time consuming. Supply is inconsistent. which l11ake5 it difficult to pl"n for large quantities of materials. On small projects, 110wever, using salvaged materials IS often possible, TI1ere IS a readily available supply of matcri?ll5 that can fit into small developments. ACWMA MULTIFAMILY GREEN aUILOINI;> GUIDELINES April ;'i()()4 ---------------------- CLOSING THE LOOP I n addition to using reclaimed materials~ another important waste reduction strategy is to donate unneeded materials, III the CQnstruction and Demolition Waste Management Plan (SI!cwurk: MIJ<'!$urO 01), stipulate that appropriate .urplus materials be resold or donated to salvage yards or nonprofít organizations. A¡~D, some building products manufacturers will take back clean, unused scraps to be made into new products (for exampie. gypsum board, ceiling tile, carpet and flber- cement products). Benefits Not only does salvaging and reusing materials redlJCe waste sent to landfills, it is also better than recycling from an environmental standpoint. The collection, transportation and processing ot recycled-content materials uses energy and generates pollution. Reusíng building maten.ls, "v en if lumber needs to be remilled or doors have to be repaired and painted"typically generJte5 less waste and pollution than recycling does, Salvaged materials are often cheaper tllan new materials, and may be of.higher quality, Salvaged timbers have tigllter grains than some new wood, for example.

OUTDOOR FURNITURE ANO PLAY STRUCTURES CCA is used to treat wood for many applications in construction and In outdoor furniture, Studies have shown that the disposal of CCA-treated wood poses 8 significant risk to the environment due to its arsenic and chromium content. Research also shows that play 5trlJctures containing CCA-treated wood may be a risk for children. For the~e reasons, CCA-treated wood has come under intense scrutiny in the past few ye¡:¡rs. In re5pÖt1Se, the U.S. Environmental Protection Agency (EPA) and the treated wood industry reôçhed an agreement to phase-out some uses of CCA-treated wood. As at December 31. 2003. most residential and playground uses of CCA-treated wood have been banned, Taking the place of CCA are two new treatment methods that do not contain arsenic, ACQ (alkaline copper quaternary) and c"pper boron alole (CBA). Although CCA-treated wood is being phased out of produotion, there are still CCA-treated furniture anel play structure products on the market. Check product literature and specifications carefully to ensure alternative pmdlJct~ are used. For outdoor furniture and play structures, recyc!ed- plastic IlJmber can be a good alternative to wood.

Specifyi ng high-quality, durable, vandal-proof. materials will make a project easiertomaintain over time, Site and building designs that encourage community ¡'nteraction will instill pride in residents and deter crime (for detailed fSCDmrTlf:ndiJtians on df:5igfl ~tr,M~giøÚI111t provlae,the foundation fOf'8,weIJ-m8int~ined, durable projet,l. 586 if/a PfiJnnirJg&'tJosign sectiom), COMMISSIONING Green building guidelines for commercial construction often recommend th.t commissioning be a part of the integrated design process. Commissioning is a systematic process of ensuring thata,li new building systems perform and interact according to orig,inal des,ign documents arid the owner's intentíon$. However. in multifamily residentialprojects-'and in affordable hou.ing projects in particular-commissioning per se is not generally performed. OM reason is.that building systems in ,large commercial buildings tend to be much more complex than, those in small-scale multifamily buildings, Also, affordable housing d~velopers often own and'operate their projects'or-reþresent the owner's ¡nterest~, so they are typically closely invplv.d in the design process and perform a high I.vel of te.ting during con,structian. Design teams might want to explare the benefits of commissioning if they are developing a large,high-ri'" rrluitifamily project with compl.x building system.. COST Over the life of a building, O&M costs will greatly outweigh construction costs, 50 it makes sense to take steps to design a durable, energy,efficient, low-maintenance building. No matter how well designed, however, every building needs to be properly operated and maintained if it is to perform well year after year, Energy- efficient hom~;;. for e"'mple, will only offer substantiai long-term cost .aving. if occupants understand how they work, This is especially true for design strategies that people m~y be unfamiliar with, 50ch as'passive solar heating, It does take time to develop manuals,signage and displays and to provide O&M trainir1g to staff ,and residents, Whiie it·s difficult to quantify the cost savings that result from these efforts, it is reasonable to assume they will contribute to a healthier, ionger,lasting, more energy-efficient buiiding. MARKETING AND COMMUNITY RELATIONS Educational displays and tours carl be an important marketing tool for developers. For affordablé housing projects, these efforts canenhance" developer's reputation among stakeholders including community and political leaders and funders., For markeHafe housing developers, displays and tours can attract positive media atter1tion, which may help drive interest from potential tenants and buyers. o U fTl ;0 » -1 o Z (f) Qo S Þ Z -1 m Z » ..../ n rrl ---------------------------------------------,--------------------,--- A(:wMA, MUI-TIFAIVII :.Y QRE:EN BUILplNG GU IJËLlNES 'April 2004 OPERATIONS & MAIN1ËNANCE PACE 3 -----------------,._---------~-------------------------------~,--- '-', :' .,-.".... -,,-¡ C iT¡ "~:Cf "j::::,.;..¡ ---I '-" i_) /' "'- ( ~) <.1" ,.;,.." ~~.::;:::::II '·"r"':;v ,"..~" " " ¿-,~ r~' , I ""~"""i ..:.;:~ ):::,C'" ~''''-"~I ~"...

The goal is to reduce the need for air conditioning to the point where it is rarely needed. Some of the solar measures, like orienting the buildings along an east- west axis, took time to work out, but will cost nothing extra to build. Other measures, like the 3-foot overhangs, have a price tag, but will significantly reduce cooling loads and the tenants' energy bill.. The table below shows how the design team approached the challenge of getting the cooling loads close to zero, beginning with the building orientation, C¡¡,tU,n¡; t'he COOUflg LOM],,", L BUILDING ORIENTATION _ Elongated along east,west axis 2_ GLAZI NG PLACEMENT - Almost all glazing is on true south and true north facad@$ 3.

An energy"efficient Kane Ecodisc elevator has been specified, Finally, a significant portion of the electricity needs will be met by a rooftop solar photovoltaic power system. MATERIALS In the spirit of "reduce, reuse, recycle," the project team focused on minimizing jobsite waste by specifying factory-built wall., setting up a plan to donate unused construction materials, and writing a Section 01505 construction and demolition waste management plan, Construction materials were selected for durability, ~101d avoidance, nontoxicity and recycled content Dozen5 of green rn.aterial5 were spe¡;:ified, including high-volume flyash concrete, fiber-cement siding, engineered lumber, FSC- certified roof trU5$es and ass sheathing, Floors are finished with recycled content carpeting and natural ¡¡noleum, HEALTH The apartments are insulated with fiberglass batts with no added formaldehyde.

COMMUNITY DESIGN Parking was moved to the rear of the $ite 50 that the homes oould oonnect with the $urroundíng community. The site ìs located on tWQ bu~ Jínes and within a short walk of a grocery store and public library. The contractor is planning to preserve a large mature tree in the courtyard, A central onsite laundry room saves capital and operating costs and space while providing commercial-grade washers and dryers that clean clothes better than residential machines. · Ti ps from the Trenches · Spend most of the design time and budget an low-tech solutions. Start the design of HVAC and lighting by trying to minimize or even eliminate anything that uses power or requires regular maintenance. Passive features that use standard construction materials are sometimes less expensive upfront¡ and are always less expensive over time. At Carmen Avenue! the passive fe~ture5 include the solar orientation; 5/8~inch gypboard throughout for thermal mass; exterior walkways to form deep south-facing overhang" high-performance glazing; and high interior volumes for ventilation and daylighting. Only after maximizing the low-tech features should effort be .pent on designing HVAC and lighting systems and controls, Don't exclude good ideas early on just because they 5eem expensive. The Carmen Avenue buildings were designed from the start with large open roof areas sloping towards true south at an ideal solar pitch to allow for the possibility of installing photovoltaics. Recognizing that nothing ever gets funded that isn't already in the design, the team designed the solar electric ~ystern before funding was found. Good ideas, even if they seem expensive, should be kept on the table at least until the end of design document.. You may find money for it, you may find a cheaper method, or you may find a good deal that you weren't aware of, In some areas technology is advancing rapidly. Elevators without machine rooms. for example, carried a significant premium when design began, but April 2004 ACWMA MlJltif;:¡mily Green B\,¡ildin¡;¡ GlJi¡jp. irl¡;~ p.3 .'m.,._ ", ) "'''1-''') .- .'T'.

The bottom line is that cost information more than three months old is obsolete. E:ncourage team IYJa!nbtm¡. to I~arfl 'from exp(;!ri~llced colleagues. ACWMA had requ..ted that high-volume flyash concrete be used on the Carmen Avenue project. The contractor had used this material before and was quick to accept it. On your projed$, if your contractors "ren't familiar with high- volume flya.h mixes, telling them that it reduces landfill wa.te i.n't likely to win them over. Instead, have your contractors talk with other contractors who have successfully used high-volume flyash concrete, Put greel1 product sales representatives to work. When making Q case for lifecycle cost benefits or when managing the submittal process in construction, get product representatives to support you, Many sal.. reps have PowerPoint presentations, lifecycle cost analysis spreadsheets and studies that support the use of their products, and some will provide assistance with submittal review and evên provide oversight of the installation. Linoleum flooring is a good example of . product that is widely recommended because of its durability and nontoxic nature, yet it requir.s a higher level of technical knowledge to install properly, On the Carmen Avenue project, Forbo Linoleum reviewed specifications and will oversee the inst.llation. .

'-- L:¡ ENERGY The building shell is insulated beyond code requirements with R-19 batt insulation in the walls. As part of the design assistance offered by ACWMA, rôised heel tru55es were recommended, The architect wôs pleased that this low-cost item would improve energy efficiency, and the contractor verified that the additional cost, if any, would be very small. Some of the double-pane, vinyl-frame windows will have low-" glazing, The drywall is 518·inch thick, which helps improve the sound separ,atiDn between units. An efficient combined hydronic system provides space and water heating. Fluorescent lights are u.ed throughout the homes, except in the dining areas where people generally prefer dimmable lights (dimmable fluorescent fixtures are available but cost considerably more than nondimmable fluorescent fixtures), MATERIALS Durability is a major focus of this affurdable housing project, so the architect selected low maintenance fiber-cement siding, 30-year roofing, and high quality hinges for cabinets, The Hardiplank fiber-cement siding is composed of cement and recycled wood fiber> and is designed to look like traditional wood siding, Linoleum flooring was too expensive tD include in all the units, so a decision was made to install it in all the ground-floor unit$, where the installation was ieast expen.ive, On upper floors, the lightweight gypcret. would have made it necessary to add an additional layer of plywood subfloor on top to guarantee proper adhesion of the linoleum, Recycled fiyash is specified to replace 28% of the cement in concrete, helping reduce CO" emi55ions ass.ociated with cement production and helping keep flyas;; Dut of landfills, Exterior benches are made from a composìte of recycled plastic and wood fiber. The architect incorporated ACWMA's model specification 01505 for a construction and demolition waste management plan, The architect and developer reviewed the implications of this specification with the contractor, The material recovery facility in nearby San Leandro is currently achieving high recycling rates from mixed construction debris boxes, so a jobsite recycling level of at ¡e.st 50% is planned tor this project HEALTH To help protect indocr air quality, tl1e design team specified low.vOC paints and glue>, f¡bergla» Insulation with no added formaldehyde, and low" emis.sion carpet and linoleum. The design team also specified medium-density fiberboard (MDF) cabinet. instead ot particleboard or other c.abinet materials that contain urea formaldehyde, While the cost of MDF cabinets may be slightly higher, they are expected to last longer and provide better air quality. The contractor's green building allowance (see TIps from the Trenches helow) made it easier to consider items like thi. that add upfront costs but offer long-term benefits, p.2 ACWMA Multifamily Green ßuilding Guidelines April 2004 ... - -. -" - GREEN at a GLANCE Key green aspect!:i of the Breakers at Bayport development are listed here.

Stormwater from the roofs and land5c.ped areas will be collected in swales between the buildings. The project team Initially explored permeable asphalt and loose-laid pavers for stormwater runofl, but the price lor these options was high and the dense soil made d,.inage problematic. AlsQ, new storm water requirements (NPDES) are steering projects toward .wales and away from Filters that require regular maintenance, The swales turned out to be the least expen5ive, and probably the best, option, InSide, the homes will have ENERGY STAR" dishwashers, and low-flow showerheads and faucet aerators_ The specifications give preference to 1.6 gpf toilets that are approved by the East Bay Municipal Water District. EBMUD's list 01 preferred toilets gives designers a tool to diFFerentiate between all the 1.6 gpl toilets on the market and select one with better performance (some toilet. rated at 1.6 gpl actually operate over 2.5 gpf once the original flapper valve is replaced). ·ï"~'· " COMMUNITY DESIGN Initial discussions between the city and the design team lavored laundry hookups inside each unit. Noting the beneFit. of centralized laundry lacilities, including w¿¡ter and energy savings and more community interaction, the dec.!.ion was made to inolllde the optilln Fot centralized laundry, In the final plan! most units were desígned to accommodate i3 washer and dryer inside a closet, while the common house will include a central laundry Facility lor resident. who do not wish to purchase their own equipment.

But for .ffordable housing, it may be necessary to find creative ways to fund these upfront costs. At the Breakers at Bayport Apartments, the developer selected a contractor early in design and then explicitly designated a portion of their base budget to cover green building-related costs. By not making the total fee larger, Segue Construction, the general contractor, had a strong incentive to guide the green design toward one that could be built as simply as possible using standard construction practices. By starting with an expectation that money will be spent on green building, the process feels fair and doesn't get bogged down in controversies about basic green building concepts, Focus on durability and mold avoidance. JSW/D Architects spent considerable effort detailing the project's waterproofing elements, including details such as flashing and capillary breaks at the bases of posts. The project's drawings include a diagram showing proper window flashing details, and specify particular materials to achieve the best results. Roofing elements are also important Roof overhangs help keep water out of the walls as well as provide important shading, The roof has a 30-year warranty. Hire an intere.ted general contractor. The best way to keep cm;t5 in line is to hire a contractor who is willing to work with their subs to educate and train them if they are not familiar with particular green measures or materials. This helps counter the common practice of charging more for something just because it is unfamiliar. MULTIFAMILY GREEN BUILDING GUIDEl.INES CASE STUDY THE BREAKERS AT BAYPORT F / f.'

But it was still pos5ibl~ to include many green materiJI~ ~nd efficient 5y::..tem5, The development's key green building attributes include proximity to public tranSit, use of low-toxicity materials, energy-efficient lighting and appliances, and recycled-content roofing and flooring materials, Residential feature:. are designed to encourage community interaction, and include a children's play lot, 1:1 community center with kitch~rl, activity roDm5 and offices, and lawn and rnini-plaz3 areas. · What Makes it Green. ENERGY Overall, the project uses 26% less energy than allowed by Califorrlla's Title 24 energy code. All Betty Ann Gardens apartments feature ENERGY STAR" air conditioners, di5hwðsher5, refrig~rðtor5 and compact fluQrescent lamps. ENERGY STAR' products save electricity and reduce residents' utility bills, Insulalron above levels required by code and vinyl-frame double-glazed windows and sliding doors also 11elp conserve energy and keep the homes comfortable. The apartments ir¡elude combination water/space hydronic heating and cooling systems, which are generally more energy efficient and less costly to operate than conventional water heating and forced air systems, MATERIALS Many of the building materials used on this project contain recycled Content or ~re otherwise resourcE'. etticient.

Low- VOC interior paints and varnishes were used throughout the proJect, which also help maintain good indoor air quality. WATER By r.storing and protecting the nearby Penitencia Creek, project desigr1ers contributed to improved water quality and stormwater runoff management. Restoration work involved çleaning out garbagej replanting areas and adding temporary irrigation for the newly planted trees, Installation 'of eNERGY STAR" dishwashers Ilelps reduce overall water and energy use. Unfortunately, due to the project's relatively late integration of green building features, other water-conserving mea~ures 5uctl as permeable paving end drought-tolerant landscaping could not be implemented without adding burdensome cast5.

The deciwHI to more aggressively pursue grecn building strategies came late, after the p"'ject rlad already received approvals from the City of San Jose, As a re5ult, the project team had to work within tile bounds of the approved design. Some green features, like d1anging the heights and orientations of the buildings, would Ilave been feò,ib e early on, but required changes in the City', development approvals and were therefore technically and economically unfea.:.:;ihle at the later date. Fortunately, the ge·neral contractor accommodated the developerl5 green building goals, and worked with the architect to develop an alternative set of çost estimates for the green leatures.

The single-pane aluminum-frame windows were replaced with double-pane, low-e windows with vinyl frarne5. The eledric resistance baseboard heating wag replaced with efficient radi.ant cove heaters high on t.he walls with separate thermostats by room, ENERGY STAf~~ appliances were installed, and conventiQnal lights were replaced with compact fluorescent lamps in kitchens and bedrooms, The energy efficiency retrofit cost $43,942, and was so effective that payback was estimated to be 2.5 year>. The new duplex included many of these energy efficiency feaflJl'es at the design stage, MATERIALS At Johnson Creek Commons, roffen wood siding on t~le apartments was replaced with Hardlplank, a fiber-cement product t~lat is durable and uses less. tree fiber than wood siding. Sink5, countertops, doors and other fixtures were replaced with higher quality sa!v¿¡ged products. And 90% of the lumber used in the duplex construction was salvaged from oid buiidings (s." Financing section below for more information), Additionally, fhe duplex was built with advanced framing techniques. which use about 20% less lumber than traditional fri3ming. The ~mall ¡3mount of new wood that was used was FSC-certified to be sustainably harvested. Long-lasting linQleum replaced the old vinyl flooring, Recycled-content \.arpeting was ìnstalled in units and common areas. Recycled latex p£lint was u,ed for the extenors, helping keep leftover paint from other projects out of the landfill, WATER The Portland Water Bureau worked with the project owners to undertake a water efficiency pilot program in the complex, Measures included installing flow-reducing devices in toilets and showerheads; replacing olcl washing machines WiU1 water-efficient front-loading machines; and using automated rneter"reading technology to monitor the entire complex!;; water consumption. A water-efficient landscape design and drip irrigation system were inst<3lled.

Financing. From the outset, this project was intended to show how low-income housing can be durable, healthy and environmentally responsible. The owners made a realistic as5e55ment of which gre~n building rnea5ures they could include, and priorìtized key environmental goals: energy effìciency, re50urcc conservation, low toxicity and durability. Some features, such as solar hot water or photovoltaics, were never considered, due to budget restraints. other green item5-- such '" wheatboard cabinetry, perme"ble paver>, and damp-spray cellulose insulation-were initially considered, but later rejected due to cost or availability barriers. Still other items, such as hydronic heating for the duplexes, were installed with the perspective that the energy savings and reliability make this tecllnology a good long-term Investment. The duplex portion of the project also benefited from excellent support from the ReBuilding Center, which worked hard to supply the salvaged lumber package at a reasonable cost.

The project has been registered for LEED certification and its owner and designers hope thot it will attoin the Gold rating. On-Site Energy Gene¡>!1tion · Photovoltoic (PV) panels are integrated into the building focade ond ore On the rooftop. The 25-30 kW system will produce more electricity during the daytime peak hours than needed by residents. If the building is deemed eligible for net metering (see finol paragroph of the case study), the surplus electricity that is generated on site can be sent to the power grid; the building owner will then be credited for that by the utility. During non-daylight hours, when the PV system does not operate, electricity will be generated by the turbine/cogeneration system ond taken from the grid, However, the electricity obtoined from the grid should be offset by the surplus sent into the grid, Therefore, under a net metering system, the residents' electricity bills should be zero. · A 28 kW natural-gas-powered turbine with cogenerotion (waste heat recovery) system operates in the early morning ond evening hours, to meet the remainder of the electricity demand, This system also provides 100% of the building's domestic hot woter needs ond 0 substantial portion of the winter space heoting requirements. This low-emission system has 0 conversion efficiency of approximotely 70% (while primary energy delivered via the utility grid is only about 30% efficient). Also interesting to note is that, in Californio, the price of natural gos is discounted for consumers who use cogeneration systems.

This added cost is being covered, roughly half and holf, by the City of Sonto Monico and the Regional Energy Efficiency Initiative. The REEl is 0 joint program of Southern Californio Edison, the Californio Energy Coalition, and the Cities of Irvine ond Sonto Monico. It uses public goods surcharges from utility bills to Fund energy.efficiency demonstrotion projects in those two cities. Becouse REEl funds energy efficiency features only, the City covered the cost of the energy generation systems (the photavoltoic panels ond gos turbine generator). The Community Corporotion of Sonta Monica expects to receive a buy-down 01 almost $65,000 from the Californio Energy Commission for the photovoltaic :i: '\1: system, which cost approximotely $220,000. And Southern Colifornio Gas company is providing 0 $17,800 rebote on the $57,000 natural-gas turbine and cogeneration system (cost includes contractor's prevailing woge for instollation); the company will also be doing field testing on the unit to see how it performs. The system is expected to hove a payback in fewer than ten years, ond the project's efficiency measures should have 0 payback (ond net monetary benefit) in fewer than five years. The stormwater retention system was paid for by the City of Santa Monico's Public Works Department, os part of the department's program to capture stormwater at key sites within the city, in order to prevent urbon pollutont runoff into the bay. As Colorado Court is a demonstration project, it is not surprisin"g thotits designers and developers encountered some obstacles in the course of its development. One of the main lessons learned wos that the project never could have been accomplished withoutcammitment towords the project goals from all members of the team. The following are some of the challenges that they faced: Construction Waste Recycling: A new City 01 Santo Monico construction waste recycling ordinonce will take effect in the spring of 2001. Once services are in place to handle such recycling citywide and the practice becomes commonploce, it is expected that contractors ond owners will actually save money by recycling construction waste and thereby diverting it from landfills. Colorado Court served oS a demonstration project to prepare for this ordinonce. Because construction waste recycling is not yet common, and because the site was too small to allow lor easy on-site woste seporation, the Community Corporotion has had to pay a premium (on estimated $10,000) from its contingency funds to have the site's construction waste recycled. Flooring: The orchitects would have preferred to hove polished concrete floors with throw rugs in the apartments, rather than carpeting, because hard-surfoce flooring does not create the health problems that carpeting con, and because it would have saved money. However, it is common practice to include corpeting in offordoble housing units, due to perceptions of comfort and to the extro soundproofing that carpeting provides. The architects also suggested natural linoleum flooring in lieu of synthetic vinyl flooring in bothroom and kitchen areos. At first, the higher cost of linoleum was considered prohibitive (even though linoleum is much more durable than vinyl flooring and therefore has 0 lower cost over its lifetime). In the end, the CCSM was able to negotiate 0 lower price for the linoleum, because they purchosed it ond the carpet from the some monufocturer. Certified Wood: The originol intent was to use wood from certified sustainably-harvested forests for framing. However, becouse the supply of certified wood wos low during the course of the project, its price was prohibitively high. Concrete: Cement used in this project will only contain up to 10% flyash. Flyash is a waste product from coal.burning power plants ond trapping it in cement is a good way to use the woste moterial while olso strengthening the concrete_ The architects would hove preferred to use cement with 0 higher flyosh content. However, the added curing time required for higher flyash-content cement would have deloyed the project, which would hove mode it mare costly. Equipment Down$izing: It took some time to convince the mechonicol engineers to downsize the mechanical/electrical/plumbing equipment (hydronic radiators, piping, water pumps, and heat pump). But once the energy efficiency features were incorporated into the load analysis, downsizing ond system integration were deemed feosible_ Tax Credit$ for Affordable Hou$ing: The Colorado Court project was not selected for the highly competitive tax credits far low·income housing under the 2000 criteria. However, the new 2001 criteria issue points for energy efficiency_ Hod these criteria been in ploce lost year, the project would hove been more competitive, Energy Generation Regulation: The architects, energy consultonts, ond CCSM hove taken a creative and aggressive approach in incorporating the on-site, distributed power generation technologies into the project. Project teom members hove been involved in extensive coordinotion with stote government officio Is. The most significant regulatory chollenge they have faced concernS electricol net metering rules. Net metering means thot when customers generate more electricity than they consume, the electricity can flow bock into the grid and the customer's meter will run backward, The customer is credited for up to 100% of their net generation of electricity. Until recently, the state only allowed for the net metering of systems roted at 0 maximum of 10 kW of renewable power; the Colorado Court PY system con generate up to 30 kW of electricity. The City encouroged the State Assembly to odopt new legislation to accommodate larger systems. Midway through the construction of Colorado Court, the legislation wos possed, allowing for net metering of systems rated up to 1 MW (1,000 kW). However, this will not be applicable to Colorodo Court because of the woy thot Southern California Edison interpreted 0 Public Utilities Commission ruling thot seemingly precludes buildings with more than one source of on-site power generation from net metering_ This means that the project cannot reap the full benefits of hoving both the photovoltoic panels and the gas turbine. · Pugh Scarpa Kodama Architec/s, 310-828-2996, p,k@pugh-scorpo,com · Helios International, Inc.

Nueva Vista grew out of a lengrily organizing ond community design effort in conjunction with rile project's very low and low-income residents who work In the county'. tourism and agricultural sectors, and tlle green aspects of the project helped build political support from the Santa Cruz City Council. The example set by Nuevo Vista was instrumental in leading the develoCer, Mercy Housing California, one of the stote's largest developers of affordable housing, to establish green bui ding guidelines for all its future building projects.

Researching, identifying and specifying green building materiols, particularly those which hove 0 positive effect on the heolth of residents, was 0 major chollenge. The architect worked with their own appropriate materials checklist to set design criteria and explore cost implications, Later, a green design chorrette, conducted by Globol Green USA os construction documents were being prepared, helped norrow the choices ond identify creative ways to pursue green building objectives. For exomple, a system of "bid alternates" was devised so that the contractor would obtain cost in for motion for green materials thot were not included in the original budget. This enabled Mercy Housing the Aexibility ta choose and prioritize which features could affordably be incorporated inta the development.

Green-speciFic financing induded: WHY BUILD GREEN? '1;;"'.':; .~:l;' ,:,"" ;'::¡:i Even with a commiffl.d developer, 8JCperienced,cIe.ign leom,and a ho.t of extra funds available 10 the project; Nueva Vi.fa faced a number afchal/enge. in, the proce.. af creating a 'lJCce5sfulgreen project. o Construction Management: Initiolly the controctor hod some difficulty adjusting to the different "green" specificotions being considered by the design team and was reluctant to accept changes to standard construction practice. After much discussion, a process familiar to the contractor was devised whereby the contractor was asked to price certoin green moterials as bid alter notes. This required the contractor to moke an up'-front commitment to providing tne materiols ot a specified cost and ollowed the developer to calculote which of various options fit within the budget. While this system of bid alternates was crucial ta moving the project forword, it does have some drawbacks. The shortcamings of this approoch include: the need lor the design team to do a great deal of research to develop the set of olternative specs; the potentiol that green building materials will lorever be seen by controctors as on "alternote" rother tlian stondard practice; ond the possibility thot mony green features will be labeled as additional cost items ond ultimately be reiected by a less committed developer. o Corpet Recycling: In affordable housing developments, carpeting is typically chonged every 5 to 7 y'eors. This frequent rate of replacement generotes thousonds of pounds of londfill waste, on issue of porticular concern in Sonta Cruz county where existing londfills will reach capacity within 15 years. As a result, ottention focused on specifying carpet that wos made of recycled moterral and is recycloble os well. While many carpet manufacturers claim tliat their Cor pets ore recycloble - with some even offering "take-back" programs - the octual infrostructure for carpet recycling is weok. For example, one option lor recycloble carpet thot wos considered would hove required the owner to cut the old corpet into pollet-size pieces and pay to have it delivered to onother county. Another monufacturer ogreed to toke back the corpet ofter removol but could not guorantee that it would octuolly be recycled, indicoting thot it might be incineroted insteod. Eventuolly the decision wos mode to specify carpet with recycled content ond mode from nylon-6, o moteriol with recycloble properties, with the hope thot the industry ond recycling infrastructure will evolve significontly over the next severol yeors. Q Kitchen and Bathroom Flooring: Greot effort wos put into eliminating vinyl flooring - which is generolly not recycloble ond generates harmful pollutonts when monufoctured - DY using noturallinoleum in both lIie kitchen ond both. While linoleum had a higher upfront cost ($5.00/sf versus $3.50/sf for sheet vinyl), it should last 40 yeors, compared to only 7 to 10 yeors for sheet vinyl, thus significontly lowering operoting costs over time. Nevertheless, there continues to be concern obout the potentiol for moisture·related problems with the linoleum in the bothroom. Greot Core wos put into instolling the linoleum properly, while moisture build-up is minimized by providing high-copocity fons with no monuol override [as opp.osed to outomatic humidistot controls) in the bothrooms. Tenants will olso be given moteriol exploining the environmentol benefits of linoleum versus vinyl and the need for proper mointenonce. o Water Metering: To promote conservotion, the developer investigated providing individuol woter meters to the units in oddition to the individuol electricity and gas meters. This proved to 6e more difficult thon expected, os eoch meter would have required 0 seporate ond costly hook-up fee. A system of sub-metering, whereby individuol flow meters are instolled ond residents ore billed seporotely by 0 third party, could not be set up within the time dictoted by the construction schedule but remains 0 promising option. · Mercy Housing California, Owner/Developer Project Monoger: Elisobeth Vogel, 831·471-1910, evogel@mercyhousing.org · Van Meter WilliarnsPollack, Architect Architect: Fred Pollock,415-97 4-5352, fred@vmwp,com · Global Green USA,.

The building included an inefficient rodiont ceiling heating system, limited insulation, ond single-gloss glozing on windows and sliding doors, The City saw the need to reploce the rodiont heoting system as on opportunity to undertoke a more extensive energy retrofit. The City hired Sysko & Hennessey, engineering consultants, to conduct on energy audit and efficiency feasibility study, Using the TRACE computer energy modeling software for the ossessment, they prepared an Energy Efficiency Alternatives Report, which recommended vorious energy efficiency options, based on criterio such as the financial payback period ond funding potential. The energy efficiency upgrodes thot have been incorporated into the project are as follows: ContrClctar: Th~ä~ÚMeril Co_ · Solar-assisted hot water heating system repaired · Refrigerators in some units replaced with Energy Star refrigerators · R-30 ollic insulotion odded · WolI insulotian odded · Windows and sliding gloss doors replaced with dual-glazed glass · Compact fluorescent lightbulbs provided for resident~ · Thermostats with night setbocks provided · Skylights (for naturollighting ) odded to stairwells The consultants estimate thot the upgrades will reduce the building's electric energy usage by 39% ond natural gas usage by 22%, resulting in savings of more than $10,000 per year, The project also includes environmental feotures including: · Recycled plostic T rex lumber lor the patio fences · Recycled rubber mat for the playground · Low-flow showerheads · Drought-toleront plantings ¡. This praject's energy efficiency upgrades added opproximately $106,000 to the project cost. The upgrades were funded by the City of Sonta Monico ond by the Regionol Energy Efficiency Initiotive. The REEl is a joint [ program of Southern California Edison, the California Energy Coolition, and the Cities of Irvine ond Santo Monico. It provides funding for energy-efficiency demonstrotion projects in those two cities. The Energy Star )..".'. refrigerotors ond the compoct fluorescent lightbulbs were provided by Southern California Edison. Edison will be monitoring the energy sovings afforded by the new refrigerators. Limited Scope of Rehabilitation Projects: It is generolly easier to incorporate green opproaches into a new building design thon into a renovation project. Because the siting, form, and window location were all predetermined at 20th Street, the majority of the work focused on upgrading existing systems. Furthermore, because rehobilitotion projects often involve selective rehob work (replocement of moterials and finishes in only a few units), such projects do not lend themselves to high-volume economies of scale for procuring alternative materials. Standards for Green Building: The Community Corporotion of Santo Monico (CCSM) has not yet integrated the City of Sonto Monico's Green Building Design and Construction Guidelines into the internal standards used by CCSM project managers and facilities managers. However, CCSM's Minimum Standards for Rehabilitotion Projects currently do include severo I items related to green building. There are: installotion of setback thermostats, upgrading to R·19 insulation throughout the building, instollation of fluarescent fixtures in kitchens ond bothrooms, prohibiting the use of particleboard for kitchen cabinets, and requiring contractors to obtain on alternate cost for recycled carpeting, and. These standards are included in all rehab bid packages and implemented at the discretion of the individual project monagers. In the 20th Street project, plywood wos used instead of particleboard for kitchen cabinets, which greatly reduces but does not eliminate the presence of formoldehyde, In the future, CCSM is looking into specifying a no-formaldehyde fiberboard such as Medite II or Allgreen in future projects. Recycled-content carpeting was not used in this project due to cost, but is also being explored for future projects. CCSM is also researching prices and suppliers of no·VOC points ond natural linoleum flooring, Community Corporotion anticipates thot more green features will be incorporated into the Standards for Rehabilitation Projects as more products and materials ore tested in upcoming projects. Familiarity with Green Materials and Approaches: Project manogers involved with the project expressed the importance of all project teom members being familiar with green techniques, technologies, and materials. One of the major reosons that mony green materials were not incorporated into this project is that the contractors, specifiers, and project managers were unfamiliar with the materials, their perfarmance instollation and maintenance, where they could be purchased, Added Costs: Green components have 0 wide variation in costs. Some are less expensive than or equol to conventionol methods and moterials. Others have higher up-front costs, Sometimes higher initiol costs con be offset by long-term poybocks. In the 20th Street project, much of the energy efficiency upgrades were offset by REEl funds. More extensive upgrades could hove been completed if odditionol funds were ovoilable. For exomple the energy consultonts found that it waS viable to spend opproximotely $4,000 to refurbish the old solar woter heating system. However, odding new photovoltoic panels wos not deemed to be financially viable. Costs for green items should decrease over time, however, as green features become more standardized, the combination of market competition, increased availability, and opporh.mities for discounted bulk bring prices down, .

' Founded in 1986, First Community Housing's transformation into 0 green affordoble housing developer began in 2000 when the FCH Board 01 Directors determined thot FCH should refocus on being a development-driven firm whose sole mission was to build and manage high-quality affordoble housing in the Silicon Valley area of California. During this tronsformation, stoff resources were concentrated into areas most closely oligned with the development process - architectural design, construction management, dèVelopment finance and asset management. With this expertise present within the organization, new Executive Director Jeff Oberdorfer, on orchitect with experience in both the privote ond public sectors, set about to develop green performance and program stondards for all of Firót Community Housing's developments. These Minimum Stondards for Finishes, Systems and Appliances are grouped by construction specification codes and set minimum green requirements in oreos such os site work, structural framing, mechanical systems, interior finishes, applionces ond lighting. Performance targets are also set, including exceeding the California TItle 24 Energy Code by 15%, recycling 75% of IContinuc~d on Next Page] Betty Ann GaIdens 76 ONE TO FOUR BEDROOM UNITS SAN JOSE, CALIFORNIA · Rehobilitotion ofod¡ocent 'tronsit stop: Iree mass transit passes for 011 residents · Riporian restorotion and protection · Existing heritage trees inçorporoted into site plan · Low-flow water fixtures · Exceeds California Title 24 Energy Code by 25% · Dauble-glazed windows ond sliding doors · All gas appliances · Hydroniçheotingond cooling · All fluorescent light fixtures · Noturollinoleum and recycled,contentcorpet floors · Hordiboord fiber,cement siding · Reçycled·content interior trim and boseboord · Engineered structurollumber · "Eço-Stor" recyCled content roof on Community Building · Sustoinobly horvested teok benches, ond lobby furniture · Wheot çomposite office furniture · 99% recycloble office choirs · Formoldehydê-free counter substrates · No VOC and formoldehyde·free çobinets with water·bo,ed vornish · Formaldehydê-free baff insulation · Low VOC Paint (ConlirluE!d frolYI previous poge) construction waste, and powering 100% common area lighting with renewable energy.

Even with these disèounts, however, some of the green materials and systems used in First Community's projects hove higher first costs compared to standard construction practice. From a lifEXyde perspective, though, these options add long.term value to the projects, Because First Community is required to own its properties lor 40 years or more, items with a long-term poyback are justified. Another budgeting strategy is to use contingency funds that remain as 0 project nears completion lor an established "wish list" 01 green upgrodes on finish moteriols. First Community Housing's reputation as on oward- winning developer ond green builder has helped negate I the myth thot offordoble housing will creote 0 negotive impod on its "host" neighborhood and gives it a competitive edge when negotiating with local governments over potential future projects. As lenders start to evoluote the durability ond long-term sovings provided by green building materials such as linoleum, farmoldehydê-free cabinets and photovoltaic panels, FCH will be well placed to take odvantage of lower interest costs ond lower replacement reserve requirements. F AQ: HOW' TO BEOOJJ1]!' A GiU'mN I:UTOB.1MBIJ1 !1IOmmm DEVELOPED. Q: What is the fint step towards becoming a green affordable housing developer? A: Creøte ørgønizøtionøl green design standards. Many green slro/egies and 'pedFi<atians can be common 10 different type' of development" Standardi"atian works parncularly well with interior and exterior fini,he., roofing and insulation material" flooring, appliances, and Ivrni.hings. Standardi"ing building material, al,o allows lor the negonation of volume discount, from ,upplier,. Q: But every project is diHerent. Are green design stClndards flexible enough? A: Standardizing frees up time to focus on the ;nd;v;duøl chøllenges of each project. By standardizing certain elements, design costs can be concentrated on evaluating op~ions for item.s that vory by project, including site preparafion, building orientotion, ma,hanical systems, and the type and scope of renewable energy systems. Q: I am working on a limited budget and people always say that green building costs more. How can I get the right advice on cost-effective designs and materials? A: Work with architects and contractors experienced in green building. Green building experti,e i, unaven across the design and bu;lding industry Qnd for 50me professionals new fo green techniques and strategies, the learning curve con be steep. By working with individuals and firms with prior green building experience - or at a minimum with those Firms eager to do research and learn ~ developers can share the burden of paying attention to ffJe righ~ details while avoiding unnecessary ond po~ent;ally cos.tIy experimentation. Q: I've got same basic green design standards. How can I ensure that they are being met? A: Do construction management in-house. In-house con,/ruc/ion management allows the developer to bath ,et ,he green standards and ensure that they are implemented. A developer who has .strong construction managemen~ experfise in-house is at 0 distinct advan~age when trying to green its proiects.

Q: What con I do to realize the full benefits of being a green affordable housing developer? A: Track and measure performønce. Green building brings a number of-benefits to developers and residents, including lower operating and maintenance co.st$, improved resident health, and less environmental impact on the .surrounding community. But, as af yet, these benefit, are difficult to Ivlly cap'ure in term, of lower financing co," or increa,ed political ,upport lor affordable housÎng.

FCH is considering using spaces like carports os generating Facilities, with the long-term goal of selling electricity back 10 the locol u~lity, a Sustainable Sites: MDst offordoble housing developments ore dense urban inAlI projects. Constroined site conditions make certain susloinable strategies such as slormwaler management, permeable paving and natural greywoler treatment chollenging to implement. FCH sees this as 0 mojor area for innova~on, perhaps by linking sevarol proiects in dose proximity or combining future prajects with Iorger community Iond preserva~on and smort growth strategies. i:J Indoor Air Quality: Ensuring high quolity air circulation and the proper number of air changes without oversizing the mechanicol system or installing noisy components is 0 mojor chollenge. This is porticulorly the cose in kitchens and bathrooms, where moisture and other contaminents ore present in high concentra~ons.
