Describes a study of indoor air quality in 12 retrofitted houses of the Bonneville Power Administration (BPA) Midway Substation Residential Community, undertaken by LBL and BPA. Measures effective leakage areas and average concentrations of nitrogen dioxide, formaldehyde and radon before and after retrofit. Finds average reduction in leakage area of 32%. None of the pollutants measured before or after retrofit reached levels exceeding existing guidelines. Moderate increases in radon (42%) and formaldehyde (24%) concentrations observed are consistent with the estimated average decrease in air exchange rates.
