Aims: Inefficient outdoor airflow of residential complexes is one of the most important issues that has greatly reduced thermal comfort and, consequently, the tendency to be present in these spaces. The present study aims to investigate the effect of the arrangement of blocks in a residential complex in Tehran on the outdoor wind flow and received natural light by the buildings.
Methods: The research method is descriptive-analytical with the application of Design builder and CFD (Ansys Airpak 16.0.3) software, respectively, to simulate and investigate the effect of changing the arrangement of residential blocks on wind flow pattern and airflow potential. It is used around the buildings and the amount of natural light received by the building.
Findings: The analysis of the simulations indicated that the modification of distance and arrangement along the X axis (in the best case caused) caused a %7.10 increase in wind speed, and a %2.35 increase in the amount of daylight received by buildings compared to the base model. Moving the blocks along Y axis, in the optimal state caused a %3.55 increase in wind speed and %2.48 increase in the amount of received natural light compared to the base model.
Conclusion: The results of the study indicated that uniaxial displacement of blocks may have positive or negative effects on outdoor airflow, while combined displacement patterns decrease air velocity. Uniaxial and hybrid displacement increases received daylight in comparison to the base mode.
