Optimizing the Building Location Arrangement in Urban Block, in order to Achieve Heat Mitigation of Yards in Tehran

Since modifying the outdoor condition has an impact on the indoor conditions, the objective of the present research is how to create the microclimate in the vicinity of the urban block. So this study shows that if the arrangement of the location of the buildings and yards in an urban block is changed in the form of central courtyard, the microclimate will be achieved. At the end the proposed urban block will be compared with actual urban block.

analysis method is simulation method with Envi-Met software.

according to the simulation results in central courtyard and three sided courtyard in urban block under study and comparing them with the temperature in the lateral street in the same time frame, the temperature of the courtyard in hottest time of the day was 4.1 °C less than that of the street and three sided courtyard was 3.02 °C less than the street. Moreover, comparing the results of the one sided yard in actual urban block showed that approximately the temperature of the yard was as the same as the street.

This study concluded that the central courtyard and the three sided courtyard in proposed urban block can act as a microclimatic modifier. Future research can improve the microclimatic role of the proposed urban block with water and plants.
