April 12, 2012: Public Input Sought on Change to ASHRAE Standard 62.1 Ventilation Rate Procedure
ATLANTA — A proposed change to the ventilation rate procedure in the American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE’s) indoor air quality standard is open for review after modifications were made based on public input last year. 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.
