Abstract

In this study, environmental indicators in providing thermal comfort conditions for designing residential buildings for different climatic conditions in Iran have been investigated and evaluated using the standard Asher PMV model. This study suggests the effect of climatic indicators on building design using coding and the standard Asher PMV model in Climate Consultant software. Iranian cities are divided into 9 climates using the Köppen-Geiger climatology method. The environmental indicator parameters in these 9 climates include temperature, wind speed, relative humidity, metabolic rate (MET) and envelope insulation (Clo) which are used in the PMV model. Selected data for temperature between 18 and 38 degrees Celsius, air speed between 0.1 and 0.5 m/s, relative humidity between 40 and 80 percent, MET between 0.7 and 2, and Clo between 0.5 and 1.5 are generated randomly. Simulation results show that increasing temperature increases PMV and PPD, which indicates more heat and the possibility of feeling warmer in the environment. Also, the results of active methods (evaporative cooling, heating and humidification, cooling and dehumidification) and passive methods (window shading, passive direct solar heat gain) for thermal comfort in 9 climates of the country showed that for four modes (winter Clo, summer Clo, and MET), the best performance is in the mode (winter Clo 1.5, summer Clo 0.5, and MET equal to 2), and for most climates of Iran,
