An addendum defining how the American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE) ventilation standard would apply to new and existing buildings has been withdrawn from consideration.
The scope of ASHRAE Standard 62-1999, “Ventilation for Acceptable Indoor Air Quality,” under addendum 62b, would have been changed to limit the standard to new buildings, additions and changes to existing buildings specifically identified in the standard.
