12、Buildings: A Review and a Case Study,” examincd features of indoor air quality generally associated with “grecn buildings.” Authors W. Stuart Dols, Andrew Persi- ly, Member ASHRAE, and Steven J.

13、ect to “gee- ness,” the trade-off between increased ventilation and energy use. The authors concluded that this most likely was due to the difficulty in making trade-off decisions betwccn diffcult-to- quantifi parameters. “Often times indoor air quality-related issues wcrc not inen- tioned at all, a
14、nd only energy-related is- sucs were addressed,” they said. The authors also lookcd at rating sys- tcms which focus on design, not perfor- mance, and notcd that many studies have shown that design goals are not being real- ized in practice because of issues relating to construction, operation, and m

17、INGTON, Va.-The Air-conditioning and Reffigeration Institute (ARI) reports that manufactureres shipped 55 1,176 cen- tral air conditioners and heat pumps in July, a 5% increase over July, 1995. Shipments are up 13% for the year (January-July) and the indusy is headed toward a third con- secutive rec
18、ord year. The ARi says the record shipments are being prompted by unusual weather, continuing growth in re- placement and modernization, and a buoy- ant new housing market where central air conditioners are included in 80% of multi- family units. Shipments for 1996 are on pace to exceed last years 5

20、N-The Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) has prepared a re- port that documents the impacts of re- search on society. The report uses two case studies to examine methods for evaluating the economic impacts of re- search investmen
21、ts, and to establish a framework to compare research invest- ments. One of the case studies estimates the economic impact from BFRL re- search leading to the introduction of ASHRAE Standard 90-75 jor Residen- tial Energy Conservation. The other study covers BFRL research that led to an improved asph
