ASHRAE revises IAQ standard for 2013
ASHRAE has published an updated version of one of its best-known standards.
The American Society of Heating, Refrigeration and Air-Conditioning Engineers' 2013 edition of its standard No. 62, “Ventilation for Acceptable Indoor Air Quality,” establishes the minimum air-exchange rates for commercial and industrial buildings.
Updates include 10 previously published revisions to the 2010 version and a new appendix.
“The 2013 version of Standard 62.1 continues the trend of increasing clarity while adding flexibility,” said Roger Hedrick, chairman of the Standard 62.1 committee. “These changes will allow designers and building operators to meet the requirements of the standard and provide adequate ventilation airflow to occupants while reducing excess ventilation and the associated energy consumption. “
