24、 (USGBC), the Illuminating Engineering Society of North America (IESNA), and the U.S. Department of Energy. The Sustainable Buildings Industry Council, the National Institute of Building Sciences, and the Collaborative for High Performance Schools are also represented. Thanks also to members of the

The steering committee provided direction and guidance to complete this manus

26、cript within 12 months and produced an invaluable scoping document to begin the creative pro-cess. ASHRAE convened a focus group of school administrators and maintenance staff to help guide the overall concept of the document. Members included Kevin Chisholm, Susan Cook, Rick Dames, Chad Loomis, For

27、rest Miller, Karen Reager, Ervin Ritter, and Bryan Welsh, all of whom provided valuable insight into the needs of schools.The chairman would like to personally thank all the members of the project com-mittee for their diligence, creativity, and persistence. These people worked hard to produce guidan

The committee met six times and participated in conference calls to keep the document on track. Their expertise and differing views and the support of their employers made this do

29、cument possible. Thanks to Architectural Energy Corporation, Benya Lighting Design, Energy Efficient Solutions, Green Buildings Engineering, Innovative Design, McQuay International, the National Renewable Energy Laboratory, OBrien however, thoughtfully designed, energy-efficient schools can cost les

30、s to build. For example, op-timizing the envelope to match the climate can substantially reduce the size of the me-chanical systems. A school with properly designed north-south glazing will have lower mechanical costs than one with the same amount of glazing on an east-west orientation and will cost

31、 less to build. The heating systems at the Topham Elementary School in Langley, British Columbia, requires half as much heat as the next most efficient school in its district, costs half as much to maintain, and was less expensive to install. More efficient lighting means fewer lighting fixtures are

32、 needed. Better insulation and win-dows mean heating systems can be downsized. Likewise, cooling systems can often be downsized with a properly designed daylighting system and a better envelope. Some strategies may cost more up front, but the energy they save means they often pay for themselves with

33、in a few years. MORE SUPPORT FOR CONSTRUCTION FUNDINGLower construction and operating costs also signify responsible stewardship of pub-lic funds. This translates into greater community support for school construction financing, whether through local district bonds or state legislative action.ENHANC

34、ED ENVIRONMENTAL CURRICULUM Schools that incorporate energy efficiency and renewable energy technologies make a strong statement about the importance of protecting the environment. They also provide hands-on opportunities for students and visitors to learn about these technologies and about the impo

35、rtance of energy conservation. Figure 1 shows a student at Desert Edge High School in Goodyear, Arizona, accessing information from an educational kiosk.ENERGY SECURITYBuilding an energy-conserving school reduces its vulnerability to volatile energy pric-ing. The price of natural gas increased more

36、than 270% between 1994 and 2004. The price of oil continues to climb as part of an upward trend. Additionally, approxi-mately 60% of US oil is now import-ed. The United States is also import-ing electricity and natural gas. Using less energy contributes to a more se-cure future for our country and o

37、ur communities. wATER AS A RESOURCEWater is a rapidly depleting natu-ral resource. Though this Guide deals only with direct building-related energy conservation measures, water savings result in related energy savings. Wa-ter savings from low-flow fixtures and reduced water use from efficient land-s

38、caping result in related energy savings from pumping and waste disposal. Po-table water savings also result in water supply and processing energy savings of 1025 Btu per gallon of water saved.2Water is also used to produce electricity and to extract and process fossil fuels. Saving energy saves wate

39、r.REDUCED GREENHOUSE GAS EMISSIONSAccording to the U.S. Environmental Protection Agency, buildings are responsible for almost half (48%) of all greenhouse gas emissions annually in the United States. Carbon di-oxide, which is produced when fossil fuel is burned, is the primary contributor to greenho

40、use gas emissions. School districts can be a part of the solution when they reduce their consump-tion of fossil fuels for heating, cooling, and electricity. Students and their parents will appre-ciate this forward-thinking leadership.ACHIEVING THE 30% ENERGY SAVINGS GOALBuilding a new school to meet

41、 or exceed a 30% energy savings goal is not difficult, but it does take some thought. First and foremost, it requires that the school system commit to the goal. A commitment that is incorporated in district policy is helpful. An individual from the school with decision-making power needs to act as a

42、 champion for the goal. The team must be willing and able to produce a design that meets the energy savings goals. It must also ensure that the building is constructed as designed and that school system staff is trained to operate the energy systems properly.Design TeamTo help optimize your design,

43、reference your energy goal and this Guide in your re-quest for qualifications/request for proposals (RFQ/RFP). Ideally, your prospective design team is already familiar with the Guide. Regardless, the team you select should have an established record of constructing buildings that operate with signi

46、2 sc h o o l Bu i l d i n g sDesign firms that successfully coordinate project team members, bring in building users and facilities staff for input, and use an iterative process to test design concepts are more likely to achieve the 30% goal cost-effectively.If you use the prescriptive measures reco

47、mmended in this Guide, you can realize energy savings of at least 30% without computer building energy modeling. However, properly performed computer building energy modeling can help you optimize your de-sign and will result in lower up-front construction costs and energy savings that often ex-ceed

48、 50%. Consider the design teams energy modeling capabilities during the architect/engineer selection process to achieve even greater savings. Good daylighting can contribute to the 30% goal; however, it requires good technical daylighting design. If the design team does not have experience with a we

49、ll-balanced day-lighting design, a daylighting consultant should probably be added to the team. Some univer-sities and utilities provide daylighting consulting at low or no cost.Commissioning Authority (aka Commissioning Agent)A building can have the best possible design for achieving energy savings, but unless it is constructed as designed and is operated according to the design intent, it will not realize energy savings. A commissioning authority (CxA) ensures that the energy- and water-savin
