Abstract

Assessment of climatic condition in accordance with human comfort is the basic of architecture, urbanization and tourism. Therefore, estimating and comparison of comfort zones (bounds) is important and essential in various climates. In this research linked effects of temperature and humidity on human comfort condition in two different climates of Iran (Central parts and humid costal of Caspian Sea) was estimated using Apparent Temperature Index (ATI). Yazd and Sari cities were selected as typical samples for arid and humid climates, respectively. Thermal comfort conditions for 10 years statistical period of 2000 to 2009 were estimated monthly, based on the mean temperature, mean highest temperature, mean relative humidity and mean lowest relative humidity. Results show that occurrence risk of heatstroke, sunstroke and human discomfort is higher in Sari than Yazd.
