Describes a scale model test technique designed to estimate building ventilation flow rates due to wind as a function of its primary variables. Use of this method is illustrated by its application to the determination of wind-induced ventilation flow rates in earth-bermed, above-ground fallout shelters. Shelter models with 3 different sets of wall openings are tested over a range of relative wind angles varying from 0 to 90 degrees and wind speeds from 2.25 m/s to 6.75 m/s. Helium filled soap bubbles released in the approach wind boundary layer trace the flow through the buildings.
