BUENA VISTA, Fla. - Mechanical system code requirements are often based on standards developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Ventilation and indoor air quality (IAQ) systems are no exception. So, when ASHRAE announces changes to its low-rise and high-rise ventilation and IAQ standards, HVAC contractors need to listen up.
Standard 62.2-2004, "Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings," is the only nationally recognized IAQ standard developed solely for residences.
