WebAlthough AERMOD/PRIME may provide accurate and unbiased estimates (within a factor of 2) for some building configurations, a major review and update is needed so that accurate estimates can be obtained for other building configurations where significant overpredictions or underpredictions are common due to downwash effects.
Web2. Building Downwash Parameters : One of the significant effects considered in the modeling for these units is the downwash experienced by the plume from the relatively short stack due to the flow disturbance imposed by the unit itself. In order to test the effects of raising the stack to a height which minimizes these effects, that is to Good Weband with building downwash effect.
