The aerodynamics of a building can strongly influence the dispersion of pollutants released from nearby sources. Low releases may be entrained into the building's highly turbulent flow region and result in high pollutant concentrations on the building surface where building air intakes are located. High releases may result in increased concentrations at ground level down-wind of a building as a result of the building's influence on the mean flow field. High releases at distances far upwind of the building can produce significant concentrations on the building surfaces if the building extends up into the elevated plume. Concentration measurements from a wind-tunnel study for numerous release locations upwind, above and downwind of each of four rectangular buildings are presented and compared with some previous measurements and calculations.
