About 950 people attended the recent meeting in Colorado Springs for a program with 17 technical papers, four panel sessions, keynote speakers and a trade s

9、how with 90-plus exhibitors. Much of the program covered safety issues, including the new EPA regulations for off-site emergency plans. Other aspects dealt with innovations, such as designs with direct expansion air coolers. In the plenary session address, S. Forbes Pearson, Ph.D., presented the cha

10、racter- istics of well-designed and efficient ammonia systems. Systems with these character- istics, he said, are more economical than halocarbon systems and have comparable safety records. Details about IIARs meeting and Pearsons address can be found on Page 9. ASHRAE President Donald E. Holte, P.E

11、ng., emphasized environmental responsi- bility in his 1997 inaugural address. A project cosponsored by ASHRAE that fits this emphasis is Green Building Challenge 98, a two-year international effort to develop an improved method for comprehensively assessing the environmental performance of buildings

12、. Raymond J. Cole and Nils Larsson explain the projects objectives in this months Forum article. The purpose, they write, is to develop a tool that can handle different levels of assessment, and also account for regional variations. The tool is being tested in more than 30 buildings in 13 countries.

13、 The results, along with related technical papers, will be presented at a conference this October in Vancouver. SUSTAINABLE building technology also is featured this month in an article, “The Energy Impact of Daylighting,” by Jonathan McHugh with Patrick J. Bums, Ph.D., Associate Member ASHRAE, and

14、Douglas C. Hittle, Fellow ASHRAE. This article presents a strategy that reduces the annual costs of illumination by 70%. More impor- tantly, the strategy reduces the coincidence of cooling and illumination, shifting en- ergy consumption from summer to winter. In other articles: John Kettler, P.E., M

The congressmen noted that the U.S. Energy Policy Act of 1992 requires states to adopt commercial building codes that meet or exceed ASHRAE Standard 90.1- 1989, the current standard. The standard provides uniform minimum standards in the U.S. for energy efficient requirements for the

24、design and construction of new commercial buildings and high-rise resi- dential buildings. The standard has in- creased energy efficiency in buildings by 10% to 30%. The congressmen also sought informa- tion on the status of and ASHRAEs plans on the future of advanced efficiency re- quirements, refe

The structure can be used at various levels of detail (from broad to detailed assessments) a

Their most significant contribution to date has been to acknowl- edge and institutionalize the importance of assessing

38、 building performance across a broad range of considerations beyond established single performance criteria such as energy. An important indirect benefit of the GBA Tool is that the broad range of is- sues incorporated in environmental as- sessments require greater communication and interaction betw

39、een members of the design team and the various sectors within the building industry, i.e., environ- mental assessment methods encourage greater dialogue and teamwork. In this re- gard, future assessment methods will in- variably give greater emphasis to build- ing management and evaluate the links b

40、etween environmental design strategies and building operation practices. GBC 98 will explicitly review what is currently understood by the term “Green Building,” will identify the current range of typical and best performances interna- tionally and will identify our ability to con- fidently assess a

41、 wide range of quantita- tive and qualitative environmental criteria. With the likelihood of a GBC 2000 tak- ing place in the Netherlands, we will be able to chart improvements in building performance through time relative to those established at this initial Green Building Challenge.
