Better Air for Energy Efficient Homes
Today’s Well-Built Homes Require Better Ventilation
Homes built today are energy efficient with better insulation and are more tightly sealed. As a result, homes trap stale, unhealthy air inside. The ASHRAE 62.2 fresh air ventilation standard was established to ensure adequate air changes and improve indoor air quality. Exhaust-only fans like those in bathrooms supply air from uncontrolled and potential unhealthy sources like the garage, attic, crawl space, or basement and create negative pressure in the home. Fresh air must come from outdoors. The Field Controls FRESH AIR VENTILATION CONTROL (FAVC) manages fresh outdoor air intake, per Title 24, and stale indoor air exhaust to provide whole-dwelling, balanced ventilation while satisfying ASHRAE 62.2 2010, 2013 and 2016 standards.
