Abstract
AERMOD is an advanced model of the dispersion of air pollutants that supports a variety of source types and is appropriate for estimating impacts from short-range transport for distances less than 50 km. The US Environmental Protection Agency (EPA), in conjunction with the American Meteorological Society (AMS), has developed a new air quality dispersion model known as the AMS/EPA Regulatory Model (AERMOD). There is significant evidence on the impacts of buildings on dispersions of pollutants and, among the current air pollution models, AERMOD is that one that takes into account building characteristics. Due to its capabilities, the model has also been suggested by the USEPA. The current research examines the impacts of building characteristics as well as change in the dimensions of industrial structures close to a point source on the model output. Three different shapes (namely cubic, long and wide) were assumed as the building forms. Results showed that while the building dimensions increased the downwind pollution concentration was also increased significantly. Furthermore, buildings with a wide shape had greater impacts on pollution than the other two building forms. In other words, the output model shows greater sensitivity than the width of the building.
