Compares LBL infiltration model predictions with air infiltration and weather data collected by MITU. Examines 4 simplifying assumptions in the model:1. The flow through cracks in the building shell can be approximated by orifice flow 2. ""Wind-induced and stack-induced infiltration can be added in quadrature 3. Wind-induced infiltration can be represented by averaging the values for 3 typical aspect ratios 4.
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
