ASHRAE's residential ventilation standard: Exegesis of proposed standard 62.2.

In June 2000 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 first complete standard on residential ventilation for public review. 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 guidance information for the designer and/or user of the standard. This report summarizes the public review draft and attempts to address questions and concerns that those potentially affected by the standard might have. This report may also be of use to those considering public review comments on the proposed standard.
