ANSI/ASHRAE 62.1-2010 Ventilation for Acceptable Indoor Air Quality

ANSI/ASHRAE 62.1 2010 Ventilation for Acceptable Indoor Air Quality supersedes Standard 62.1-2007 and is ASHRAE's standard for indoor air quality for commercial buildings. The purpose of this standard is to specify minimum ventilation rates and other measures intended to provide indoor air quality that is acceptable to human occupants and that minimizes adverse health effects. This standard is intended for regulatory application to new buildings, additions to existing buildings, and those changes to existing buildings that are identified in the body of the standard. This standard is intended to be used to guide the improvement of indoor air quality in existing 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.

ANSI approved.
