Abstract
Natural ventilation is one of the most important passive strategies to reduce building energy use, provide thermal comfort, and improve indoor air quality. It is one of the key solutions for sustainability in the building industry. On the other hand, natural ventilation is potentially dependent on climatic conditions and varies considerably from one region to another. In this study, the feasibility of passive cooling and natural ventilation has been assessed for various cities in Iran. Based on Köppen-Geiger climate classification, the Iran climate is segmented to nine climates. The impact of climatic conditions on natural ventilation of buildings was assessed using the Köppen-Geiger method and several selected cities in these climates using Climate Consultant software using the ASHRAE 55 standard method. By importing the climate parameter file of the selected cities into the Climate Consultant software, output results including comfort conditions, natural ventilation, and other results were obtained for 9 climates of Iran. The results showed that the climate of Abadan city with 673 hours provides the most natural ventilation, and the climates of Rasht and Anzali cities with less than 10 hours provide the least comfort using natural ventilation. Also, the cities of Yazd and Sabzevar have the highest potential with 25.8 percent and 22.5 percent per year, respectively, and the cities of Anzali and Meshginshahr have the lowest potential for using evaporative cooling systems (water coolers) with 0.1 and 0.8 percent, respectively.
