Pressurization test results: Bonneville Power Administration Energy Conservation Study.

Presents the results of air leakage measurments in 18 single-family detached houses at the Midway substation, Hanford, Washington, performed as part of the Bonneville Power Administration Energy Conservation Study. Compares the change in energy consumption following various retrofit strategies. Measures air leakage in each house with the fan pressurization technique, before and after retrofits are installed. Finds no significant change in infiltration rates in those houses receiving either no retrofits or insulation only, and an average reduction of 17% in leakage area in houses retrofitted with storm doors andwindows. Proposes extending the study to investigate the potential for further savings in energy use from reduced infiltration.
