The calculation of air infiltration rates caused by wind and stack action for tall buildings

Abstract

By applying the pressure data obtained from a wind tunnel model study to a computer model building, a simple procedure for calculating exterior wall pressure differences and air infiltration rates for various wind velocities and direction was developed. This study has indicated that the overall infiltration rate is governed by the larger of the two motive forces and that the exterior wall pressure differences at any level caused by wind and stack action are additive.
