Ventilation for Acceptable Indoor Air Quality
Developed by American Society of Heating, Refrigerating, and Air-Conditioning Engineers, ASHRAE 62.1 was published in the summer of 2010.
ANSI/ASHRAE Standard 62.1-2010 supersedes Standard 62.1-2007. It is ASHRAE’s standard for indoor air quality for commercial buildings. The 2010 revision adds new minimum filtration/air-cleaning requirements, minimum requirements for when ventilation systems must be operated, and a Natural Ventilation Procedure. Other revisions include a more robust IAQ procedure, demand-controlled ventilation system design requirements, requirements for separation of intakes and exhausts, and ventilation rates and occupancy categories.
