ATLANTA, GA — The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) announced that its proposed residential ventilation standard is now undergoing a third public review.

The new review for ASHRAE Standard 62.2P, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, began on April 5, 2002. The 45-day review period will end May 20, 2002. The draft is open as an independent substantive change, meaning only limited portions are open for public comment at this time.

"We made significant progress in the second review and have only a few changes to propose in this third review," said Max Sherman, chair of SSPC 62.2P. "We anticipate continued progress toward a quality standard on residential ventilation."

One change was removal of a requirement that bathroom fans meet sound ratings. Kitchen fans still must meet noise limitations, he said.

In addition, Appendix C, which provided information on pollution sources, exposures, and control, was removed. After hearing concerns that the appendix contained out-of-date, incomplete, or inappropriate sources, the committee decided to delete the appendix.

"As a result of some comments, we realize that there are areas that should be addressed in the standard, but for which there was insufficient information available to do anything right away," Sherman said. "In these areas, the committee will work toward developing addenda and will invite appropriate commentors to assist."

Comments received during the review will be considered by ASHRAE in developing the final standard.

Drafts of ASHRAE's proposed standards are available only during their public review periods. To obtain an electronic draft version of ASHRAE 62.2P, log on to ASHRAE Online at
