چکیده:
This article addresses the analysis of the mechanism of natural air flow around the residential
buildings and the effect of the form of residential buildings on air flow among four building forms in Tehran. The aim of this research is to study the effect of the form of residential buildings on the mechanism of natural air flow with the purpose of optimally utilizing clean air. The research method is to use computer modeling and model analysis in the related software and conclusions have been achieved using comparison of outputs of the models produced. Accordingly, four samples were first selected from software forms and modeled in one commercial micro-climate simulator software. They were tested by entering Tehran climatic data and results were extracted as simulation images.
Since the analysis was conducted in one hour interval in the morning of the 23rd of December 2013 among four selected forms. The results helped us to choose the optimal form among these cases. Thus, a general rule was not given regarding the case that the selected form is the best in all aspects. Research achievements indicate that building forms have a significant effect on local winds and air pollution reduction. Therefore, the general form of buildings affects the degree and type of pollution dispersion due to carbon dioxide and the retention effect of suspended particles.

ABSTRACT Keywords : Air flow, Local winds, Residential Building Form, Pollution Dispersion, Retention of Suspended Particles.
com housing pattern of Tehran (Mahdavinejad, Ghasempourabadi & Ghaedi 2012), attempt to establish a reconciliation of teaching based on Iranian traditional architecture and the needs of contemporary cities.
On the other hand, the main problem is that tall buildings, if inappropriately located, inhibit the wind flow, increasing "retention effect", "air pollution" and formation of "heat islands" in various regions in a city.
Literature Review Wind: Significant studies have already been done regarding the effect of air flow (Mahdavinejad & Abedi, 2011) on the degree and type of energy consumption.
Fig. 1: wind in the urban spaces (Source: Davis , 2005, 52) The effect of air flow and particularly local air flow on the energy pattern in the building based on the thermal behavior of building roof (Mahdavinejad et al.
The purpose of the present study is to investigate the effect of form of selected residential complexes on the natural air flow procedure with the aim of optimally utilizing clean air.
)) Research questions are then answered through examining the effect of form of residential complexes on air flow to analyze the wind behavior around the residential buildings and their public spaces in the selected domain located in Gheitarieh.
