Ashrae's residential ventilation standard : exegesis of proposed standard 62.2.

In June 2001 ASHRAE's Standard Project Committee on "Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings", SPC 62.2P, recommended and the Board of Directors approved ASHRAE's second complete standard on residential ventilation for public review; this was followed by public reviews of independent substantive changes in 2002 . The standard is an attempt by the Society to address concerns over indoor air quality in dwellings and to set minimum requirements that would allow for indoor air quality and energy efficiency measures to be evaluated. The standard has requirements for whole-house ventilation, local exhaust ventilation, and source control. In addition to code-intended requirements, the standard also contains information for the designer and/or user of the standard. The standard has been the focus for a variety of special interests, who have developed various approaches for delaying the development of the standard. This report summarizes the public review draft as currently being finalized for its fourth and what is hoped to be its last public review.
