Investigates the reliability of the single-room infiltration model used in the computer program ENCORE. Compares calculated air change rates with tracer gas (N2O) measurements in 25 identical one and a half storey detached houses. Describes the infiltration model, the parameters and some results. Thecomparison shows good correlation at low wind speeds (< 3m/sec) but the model's values at higher wind speeds are too high.
Studies the predictive accuracies of infiltration-pressurization correlation models by subjecting a group of identical homes in Freehold NJ to both pressurization and tracer gas measurements of infiltration. Compares infiltration and pressurization test results. Uses four air infiltration models to predict the infiltration rates in the houses, and compares these predictions with the measured rates. Makes predictions using several different values of the inputs required for the models, and studies the effects of varying these inputs.
Describes a programme undertaken by the AIC to validate mathematical models of air infiltration. Uses experimental data to assess the reliability and full range of applicability of air infiltration models, and to identify key parameters that
