Abstract
Due to the rapid urbanization phenomena around the world, high concentrations of vehicular pollutants have degraded the outdoor air quality, resulting in several health risks. Numerous strategies have been developed to overcome these harmful risks by enhancing the dispersion of air pollutants. Accordingly, a question arises regarding the potential effects of urban, and building morphology on the dispersion of pollutants to decrease the vehicular pollutants’ risks, hence promoting the outdoor air quality. Consequently, this thesis investigates the effects of the urban, and building morphology to promote air pollutant dispersion at the microclimate level. Four urban alternatives with fourteen buildings’ prototypes are proposed to promote the outdoor air quality in the Mubarak residential blocks, as a case study in Port Said, Egypt. Various urban, and buildings forms are compared with a simple building form to identify the patterns of PM10 dispersion within a given time sequence. Transient three-dimensional Computational Fluid Dynamics (CFD) simulations are performed with four specific inflow conditions. The performance of alternatives are comprehensively assessed at specific points, and the results indicate that the proposed urban alternatives can reduce PM10 concentrations by approximately 36–71% compared with the current case in the studied time sequence. In addition, the integration of buildings morphological forms can effectively raise the reduction of air pollutants nearly 66–100%, which reflects the influence of urban and building morphology on promoting outdoor air quality. Finally, this study innovates a suggested computer program, U&B Pro. Air Quality Software, which enables urban planners, and architects to select the most appropriate alternative to enhance both of the outdoor, and indoor air quality.
