Infiltration - pressurization correlations: detailed measurements on a California house.

Describes detailed study of infiltration rates measured with a tracer gas and air leakage rates obtained from fan pressurization in small, 3 - bedroom California house as part of a larger study. Finds surface pressure measurements are an essential step in process of finding a correlation between natural air infiltration and air leakage by pressurization. Measurements also show significant duct leakage and air flow between attic, living space and crawl space. Concludes by listing additional work to be done before it is possible to model adequately infiltration processes in house under investigation.
