Abstract

Background and Objective: Increasing population and construction of tall buildings have multiplied the presence of environmental pollutants in cities. On the other hand, people use open urban environments more than before to meet their living needs. In this regard, various factors such as the layout of buildings and the presence of continuous wind currents can play a significant role in the distribution of pollutant particles. The present study was conducted to determine the effect of the layout of high-rise residential buildings on the distribution of pollutant particles by recognizing the air flow in Tehran. Method: In this research, using descriptive-analytical and comparative methods, using simulation technique using ENVI-met software, wind behavior around the distribution of pollutants has been investigated and analyzed. The method of data collection has been done through library studies and field survey. Findings: According to the modeling of the two different types of layout of selected urban block (Sobhan residential complex in Gheytariyeh district, Tehran)with similar building form– one as the existing situation and the other as the proposed model with orderly layout, the findings demonstrate that the layout alternation of residential blocks affects the Natural Airflow and wind speed between blocks and an improper and non-methodical locating of high-rise buildings causes a change in natural wind pattern and consequently, leads to secondary effects resulted from intensification or stagnation of wind and thus, influences the Dispersion of Pollutant Particles. Discussion and Conclusion: In this research, the obtained results from the two models of buildings layout in the software and the output related to the intensity of wind and the retention level of CO show that the existing situation model is more desirable compared to the proposed layout due to more unified and higher wind speed throughout the site and also proper air circulation between blocks which causes the dispersion of pollution and prevents the retention of pollutant particles.
