Reports on a comparative study of residential infiltration as predicted by computer model and as measured in the Mobile Infiltration Test Unit (MITU) as well as in selected test houses, both occupied and unoccupied. Sensitivity analyses were also conducted on each parameter contained in the model against data obtained from MITU. Describes the predictive model which projects infiltration rates based on selected building and site parameters and localweather conditions, and the MITU, a portable test structure designed to continuously monitor air infiltration, local weather, and indoor-outdoor pressure differences. Determines that the most critical parameters for accurate prediction of infiltration in residences are the leakage area of the building shell and the degree to which the structure is shielded from the wind.
