Energy conserving retrofits and indoor air quality in residential housing.

Assesses the impact of energy-conserving retrofits on air leakage and indoor air quality for several houses that are part of a weatherization programme in the Pacific Northwest offered by a power and light company. Indoor air quality was measured using the Energy Efficient Buildings (EEB) mobile laboratory containing sampling, monitoring, and calibration equipment. Leakage area of the building envelope was determined using the fan pressurization technique. Impact on indoor air quality by the retrofit was minimal, there was no significant change in either leakage area or pollutant concentration before and after the retrofit.
