Impact of energy conserving retrofits on indoor air quality in residential housing.

Assesses the impact of energy conservation retrofits on the indoor air quality of residential buildings, through a field monitoring project in which air leakage, air exchange rates and indoor air pollutants are measured before and after retrofit. Uses a mobile laboratory to make detailed on-site measurements of air exchange rates and concentrations of pollutants in 2 houses, and measures effective leakage area in 7 other houses. Impact on indoor air quality of the energy conserving retrofits seem to be minimal. On the other hand, potential for reducing air leakage is not fully realized, and theductwork appears to be very leaky.
