In a time when the U.S. economic stimulus plan is emphasizing retrofitting commercial and residential buildings, ASHRAE has approved a change to its residential ventilation standard to encourage home retrofits to improve indoor air quality.
“With the U.S. economic stimulus having a great deal of focus on weatherization and other residential retrofits, we developed this change to help improve indoor air quality for public health and safety,” Steven Emmerich, committee chair, said.
Addendum e to ANSI/ASHRAE Standard 62.2-2007, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, allows alternative methods for meeting the standard’s requirements regarding kitchen and bathroom exhaust fans. The standard currently requires fans in those rooms.
