ASHRAE Proposes to Move All Residential Ventilation Requirements to One Standard
Dwelling units of multifamily buildings of any height would fall under ASHRAE’s residential ventilation standard, 62.2, under a proposed change designed to provide consistency of ventilation requirements.
Currently, ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality, has responsibility for multifamily residential buildings 4 stories or more, while ANSI/ASHRAE Standard 62.2-2013, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, has responsibility for residential buildings 3 stories and less.
The proposed changes are being made via addendum a to Standard 62.1-2013 and addendum g to Standard 62.2-2013, which are open for public review from April 4 to May 4, 2014.
