Indoor air quality procedures

Indoor air quality procedures

One of two procedures listed in ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) Standard 62-1989 to determine appropriate ventilation rates for buildings. The IAQ procedure provides a method of measuring and controlling outdoor airflow in order to keep harmful substances diluted to acceptable levels. It is inherently a more rigorous strategy than the ventilation rate procedure because it considers all contaminants.
