About the Author John E. Janssen chaired Standards Project Committee (SPC) 62, which developed ANSI/ASHRAE Standard 62–1989, Ventilation for Acceptable Indoor Air Qualtiy and also served on the SPC that wrote Standard 62–1981. Until his retirement, he was a principal research fellow at Honeywell. Janssen has authored several Journal articles, including “The V in ASHRAE, An Historical Perspectiv...

OBJECTIVE To describe the role of the tobacco industry in the development of ventilation standards for indoor air quality by influencing the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE). METHODS Review of tobacco industry documents available on the internet between January 2001 and March 2002. Search terms included "ASHRAE", "ventilation", "minutes", "me...

In 2001, the Texas State Senate passed Senate Bill 5 to reduce ozone levels by encouraging the reduction of emissions of NOx that were not regulated by the Texas Natural Resource Conservation Commission. These include point sources (power plants), area sources (such as residential emissions), road mobile sources, and non-road mobile sources. For the building energy sector, the Texas State Legis...

Evaporation rates and total energy loads from an unoccupied, heated, outdoor pool in Fort Collins, Colorado were investigated. Pool and air temperatures, humidity, thermal radiation, wind speed, and water loss due to evaporation were measured over 2 1 test periods ranging from 1.1 to 16.2 hours during August and September, 1992. Data were analyzed and compared to commonly used evaporation rate ...

A set of enhancements to the ASHRAE Handbook are presented to demonstrate the effectiveness ofmultimedia and advancedpresentation techniques, such as three-dimensional computer graphics, visualization, and animation techniques. These results can also serve as a model and guide for the broader use of these techniques in other ASHRAE publications. GENERAL INTRODUCTION TO PROJECT In this paper, we...
