Abstract
The climate controls all aspects of human including his comfort in the environment. The Tehran urban area is a very complicated and problematic region for living. For this reason we have decided to evaluate its climatic conditions from to see if it is comfort for its dwellers. We have used different indices to choose the most applicable one. For this purpose the hourly data of temperature, relative humidity, water vapor pressure, wind speed, and cloudiness of Mehrabad, Dowshan Tappeh, Geophisic, Tehran Shomal, and Chitgar stations were obtained from the Meteorological Organization of Iran for the 2001- 2010 period. The comfort indices of Equivalent Temperature (Teq), Effective Temperature (ET), Radiation Effective Temperature (TRE), Universal Thermal Condition Index (UTCI), were calculated from these data in the environment of BioKlima software. Their results were compared for the different times of the day. The results showed that the Equivalent Temperature (Teq), Effective Temperature (ET), and Radiation Effective Temperature (TRE) indices were suitable for the 9:30 am and 3:30 pm. But the UTCI was suitable for the monthly and 9:30 pm conditions.
