Oct. 6, 2011: Alternative to ASHRAE Standard 62.1 Ventilation Rate Procedure Proposed
ATLANTA — The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) announced that public comment is being sought on the proposed allowance of an additional default value to the ventilation rate procedure in ASHRAE’s IAQ standard.
ANSI/ASHRAE Standard 62.1-2010, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings. The ventilation rate procedure provides a prescriptive method for determining minimum ventilation requirements. It accounts for pollutant sources from both the building and its occupants, and allows the designer to account for the efficiency of different ventilation systems when delivering outdoor air to the breathing zone.
