Abstract
The influence of the building’s configuration on the air flow pattern and the amount of pollutant entering the buildings was investigated. Six common forms of low-rise buildings in Shiraz City were evaluated as investigated patterns. Each of these forms were placed in four rotation modes (24 case studies in total) in an urban regular pavilion-shaped context, placed in the vicinity of an urban highway (as a source of pollutant production) and were simulated using Computational Fluid Dynamics (CFD). In this research, air velocity and NO2 concentration were considered as the air quality parameters. Steady 3-dimensional flow was used to simulate these cases using the SST k-
