DORAVILLE, Ga. — Purafil Inc., a manufacturer of gas-phase air filtration systems, is introducing an energy-savings program that reduces the need for outside air by 75 percent in commercial buildings and is said to offer significant savings on energy and operational costs.
The “Enersave” program is based on a recent interpretation of ASHRAE Standard 62-2001. It uses the standard’s IAQ Procedure, which “allows the use of any amount of outdoor air deemed necessary” if the designer can show that indoor air quality is acceptable to human occupants, according to the standard.
