Proposed addenda to an ASHRAE indoor air quality standard would set minimum ventilation rates and other requirements for commercial and institutional buildings.
The proposed addenda to ANSI/ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality, would add air cleaning requirements to section 6 of the standard. If approved, systems in non-attainment areas for particulate matter with diameter 2.5 microns (PM2.5) would need to use intake air filters with minimum efficiency reporting value (MERV) 11, according to ASHRAE.
In addition, systems in areas designated by the U.S. Environmental Protection Agency as “serious,” “severe,” or “extreme” non-attainment areas for ozone would require ozone air cleaners with at least 40 percent efficiency.
Also open for public comment is addendum 62.i, which would change minimum outdoor airflow requirements for zones with environmental tobacco smoke as described in section 6.2.9, according to ASHRAE.
Proposed addenda to ASHRAE standards are available during public review periods.
