ASHRAE Proposes Specific Location for Outdoor Air Intakes For Standard 62-1999
Requirements for the location of outdoor air intakes are specified in a proposed addendum to the American Society of Heating, Refrigerating, and Air-Conditioning Engineers’ (ASHRAE) Standard 62-1999, “Ventilation For Acceptable Indoor Air Quality.”
Minimum separation distance requirements between common outdoor contaminant sources, such as exhaust vents and loading docks, and outdoor air intakes are specified in addendum aa, according to Andrew Perisly, committee chair. It also sets requirements intended to limit rain intrusion and entrainment and for bird screening.
