36、the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004, EnergyStandard for Buildings Except Low-Rise Residential Buildings. The 50% AEDG seriesaddresses building types that represent major energy users in the commercial building stock.This Guide is the result of the dedicated, collect

37、ive efforts of many professionals who devotedcountless hours to help hospitals use less energy.The primary authors were the 12 members of the ASHRAE Special Project 136 Commit-tee (SP-136) who represented the participating organizationsprimarily ASHRAE, the Amer-ican Institute of Architects (AIA), t

38、he U.S. Green Building Council (USGBC), the IlluminatingEngineering Society of North America (IES), and the U.S. Department of Energy (DOE). TheAmerican Society for Healthcare Engineering (ASHE) was also represented. Thanks also tomembers of the ASHRAE Standing Standards Project Committee (SSPC) 90.

39、1 and ASHRAETechnical Committee (TC) 9.6, Healthcare Facilities.The project would not have been possible without DOEs financial support for projectcommittee expenses, Guide development, National Renewable Energy Laboratory energymodeling analysis, and committee leadership. The Chair would personally

40、 like to thank Jere-miah Williams, the DOE technology development manager in the Building Technologies Pro-gram, for his support and leadership.The chair would also like to thank all members of the project committee for their dili-gence, creativity, persistence, and willingness to take time to suppo

41、rt this Guide. They workedextremely hard to pull together practical, technically sound information covering all aspects oflow-energy-use hospital design. Their expertise and differing views greatly enriched this publi-cation. The authors brought many years of experience and good practice in design,

42、construc-tion, commissioning, and operation of hospitals to achieve significant energy savings.The project committee met four times and held four conference calls in ten months. Eachface-to-face meeting required two nights in a hotel; thus, the chair would also like to expresshis appreciation to the

43、 authors families for their patience. The chair also gratefully acknowl-edges the support of the project committee members employers, including Owens Corning;HOK; Stantec; Mazzetti; KJWW Engineering Consultants; Trane, a business of IngersollRand; CRS Engineering Inc.; University of Washington; Clev

46、ort and participation of DOE. Its members provided direction and guidance to com-plete the Guide within 12 months. The Steering Committee assembled an expert team ofauthors and defined a scope that kept the project committees task manageable and focused.The representatives from these organizations b

47、rought a collegial and constructive spirit to thetask of setting policy.In addition to the voting members of the project committee, a number of individualsplayed key roles in the Guides success. Specifically, thanks to the ASHRAE meetings staff,the American Society for Healthcare Engineering, and MD

48、 Anderson Cancer Center for serv-ing as gracious hosts at their facilities.Twenty people participated in two peer reviews, providing more than 1000 remarks thathelped strengthen and clarify the Guide. Their thoughtful input is much appreciated and thechair hopes they see the impacts of their recomme

49、ndations in the finished publication.A huge debt of gratitude is extended to the authors of the previously published 30% and50% AEDGs, for they paved the way and defined basic structure, content, and format, as wellas reporting and review procedures. Following in their footsteps has resulted in consistencyamong the AEDGs and has been a tremendous time saver. Building on their success enabledthe project committee to finish its work promptly.Additional thanks to the ASHR
