ASHRAE Standard 62.2: What is it, what’s new, and who’s using it



Steven J. Emmerich


Readers of the November 2010 IAQ Applications column by Bud Offermann learned about a large, residential IAQ study that highlighted the importance of mechanical ventilation in U.S. homes. ASHRAE Standard 62.2-2010 Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings is the only national consensus standard for residential ventilation and indoor air quality (IAQ) in the United States. However, it is by no means the only document that determines ventilation and IAQ practices in U.S. homes. This column provides an update on Standard 62.2 including a summary of some recent changes and a discussion of future directions. It also discusses the use of Standard 62.2 by building codes and in various “green” building programs, as well as other documents influencing residential ventilation and IAQ.
