The Study architecture of Tehran municipality, District 5 is based on climatic elements

With respect to Mehrabad Station, District 5 is located at the longitude of 51° 19’, latitude of 35° 41’ and height of 1191 meters with special topographic conditions. the district is warm and dry in summer, and cold and dry in winter. The study on climate and architecture of District 5 is conducted aiming to use the climatic elements to provide comfort. The data of Mehrabad synoptic station during a 20-year statistical period (1981-2010) were used to achieve the goals of the present study. According to the methods such as Olgi and Climate Consultant (software), the bioclimatic conditions were used to determine thermal comfort zone. The results obtained from the research show that the appropriate direction for constructing building would be north – south direction stretching along east – west. If laws of architecture are executed using thermal comfort indices, duration of using heating and cooling units in building located in District 5 of Tehran will be reduced.
