SUMMARY OF GREEN BUILDING BENEFITS 49. Chapter One: Overview of Green Building ~ ~ ~ ~ ~ ~ ~ ~ ¡; Ii Overarching Principles of Green Building 1 2 3 Build for the long-term Build a home that is durable and long lasting, Build for our children Make their environment safe, Build for the planet Use materials from sustainable resources, _..n..___ 5 ACrOSS the country, in response to buyer demand, homebuilders are constructing homes ¡¡ ~ that are more energy-efficient, healthier and more durable - better known as "green i building," Builders are changing tile way they design and build, while enjoying increased i'; i5 market share and faster sales. /)' ~ About Green Building Green building is a whole systems approach to the design, construction and operation of buildings - from the early stages of development through the final finishes in the home, This approach benefits both builders and homeowners by reducing resource consumption and improving livability, ô b ::2> ~ I_n ,n is u w " o ~ " w Z ~ S' ," ',. j w Q ~ " " " g Green building benefits are spread throughout the systems and features of the home, Green buildings use recycled-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, Homebuyers 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 Building Guidelines were developed to bring technical and marketing expertise to Alameda County builders, The Guidelines 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" focus on practices and approaches that are most relevant to Alameda County, '" z ¡¡¡ ~ " Every builder struggles for market differentiation, Building green is a practical 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 sense, To demystify the process and move forward with your construction project, it is helpful to think of green building as the convergence of three fundamental objectives: 1 Conserve natural 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 alternative to old-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 lighter 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, buildero 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 major 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 quality, 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 uwade to high-efficiency appliances, Other energy upgrades include installing solar water heaters and photovoltaic panels, ~ ~ ~ o ~ ~ ~ m ~ ~ ~ ~ ~ ~ ~ m m z m ~ ~ z ~ ~ ~ ~ z m ~ ~ " ~ z m ~ ~ " ~ m 8 v¡ .., ~ Q " z - Indoor Air Quality- !1 !j ôi ~ 1i :; i!i 11' ~ 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 deveiop respiratory disease, in part. due to the Chemicals in their homes. Poor indoor air quality is caused by the offgassing of chemicals found in many building materials as well as mold and mildew that build up In pool1y designed and maintained heating and cooling systems, 15 E &! ¡;; z 8 w :;; " ~ ~ '=# ~ :;' "' ~ w " :5 " ~ z 9 ::1 œ ~ w w ~ ~ One of the most common indoor pollutants is formaldehyde, a suspected human carcinogen, Kitchen cabinets, countertops, 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 is a telltale sign that there are harmful chemicals in the indoor environment. U5ing Solvent-Free Adh~i\l~5 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 contain less volatile compounds are now commonly available from most m¡¡jor manufacturers at costs comparable to conventional products, '¡ê'Yh~,g!.atE!:¡d uUdi i ': !ii!~~'!

Approximately 70% of the respondents Indicate that It is essential or very important for new home communities to be developed with greenlenergy 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 range in cost - some of them cost no more or even less than conventional options, When green building is designed into the prqject 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 Guidelines 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, ~ ¡¡ ~ Ii: ~ ~ " ~ " 2 ~ ~ IT< Z .' ~ ¡::: º " " <.:::: is " ¡¡¡ ~ ~ o ~ " IT< " i'; ~ 8 " '1 ~ ? ~ ~ 1"1 \''''1; '" adding green features as the matures, If you start gradually, you are likely to make expensive mistakes, It is critical to ¡per the changes you make and the additional costs you 'II 'incur. The earlier you start integrating alternative 8rs and green design into your building process, the 'I itl'[lay cost you and the consumer in the long run, "M~j Gelling Started A strategic way to start building green Is to develop green options, and then describe the environmental features and benefits to the homebuyer, Giving your customers a choice allows you to refine your product and market approach, Home buyers speak their own language, and understand and embrace green building only when it is explained in their terms. 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, In top-down order, responses were: 1 energy efficiency features ;m~~llØilil~~¡II;¡iil¡II1í'~9% 2 kitchen cabinet upgrade lii:I~¡¡~I\jI~II¡'~,~!Ii¡iln 65,5% 3 improved indoor air quality i¡:i::::<¡::/.",49,6% illilllllllllll_159,0% :;;;;.2000 tJi 2001 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 prqiects, What makes a home truly green is a combination of ail 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, OO..-ing segregated packages is a starting 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, Pleí:l~nt Hill COHousing COlnmon House, Plc-:asant Hili, CA ~ d ~ ~ ~ ~ ~ ~ ~ ~ ~ ~~"·'m""''''·_ " ~ :;: z ~ ~ ~ z <> " ~ ~ i" ~ '" ."

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, Using water more efficiently only makes sense as popu- lation growth puts stress on a limited resource. õ E ~ ~ ~ '" " 8 '" ¡¡ z " w " ~ 0' ~ 2: g s " " " g :s " z "' w ~ '" Consider offering ¡he following as part of a Natural Resource Package; Engineered lumber - 05B, wood Ijoists Recycled newsprint cellulose insulation Water-conserving plumbing fixtures Fiber-cement siding and trim Recycled-content decki ng Recycled-content carpet Treated wood that does not contain arsenic or chromium Energy Effic iency Package Energy upgrades are one of the first things that consumers would pay extra 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 not 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 I nsulated foundation Indoor Air Quality- Package While energy efficiency is at the top of the consumer list, improved indoor air quality- is also a priority for homebuyers, Almost nine in ten respondents of the Survey are aware of products that emit gas chemicals into their living environments, 75% or those people say it's extremely or very important to live in a home free of toxic chemicals, Consider offering the following as part of an Indoor Air Quality Package: Formaldehyde-free insulation No or Low-VOC paints Solvent-free wood finishes Less-toxic adhesives Natural linoleum instead of vinyl flooring FSC-certified wood or bamboo flooring instead of carpet Sealed particleboard in cabinets and countertops - "~I 1::-: ~ ¡¡; Green Points is a rating system that has been developed to offer builders, homeowners and municipalities a tool to assess how environmentally friendly or "green" a home is, The rating system is based on the various green features incorporated into the home, A home that has earned 50 points or more across the 3 main green building categories - Indoor Air Quality, Energy Efficiency and Resource Efficiency - can be considered a " ~ " "green home", Total points required may be adjusted in the future, The rating system was developed in coordination. with local builders, city planners and building officials, To simplify the system and to avoid double counting, each measure is assigned to one specific category, even though many of them can be placed in multiple categories, A, Site POINTS PER CATEGORY (esllurr.I!S Enl!f!lY tAQ/HeillU! ,.

To be a su~cessful 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 builders, 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 sold 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 loyalty and creates referrals, Educate Your Sales Stall 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 dearly 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 adctess this is to sort the features In terms that are Important to the buyer. Use the Green Building Benefits 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, Use these benefits to assemble the story of how your homes are different from those built by the competition. ~ m F ..
