Abstract
In this research, the performance of natural ventilation in providing thermal comfort conditions for designing passive methods in residential buildings for different climatic conditions in Iran has been investigated. Iran climate is divided into nine climates based on the Köppen-Geiger climate classification. By utilizing the Köppen-Geiger method and selecting a few selected cities in these climates, the effect of climatic conditions on residential building design was proposed using climate consultant software and the ASHRAE Standard 55 adaptive thermal comfort model. This model is recommended for thermal comfort in buildings cooled by natural ventilation and without air conditioning equipment. By importing the weather parameters file of the selected cities into the climate consultant software, the output results, including a psychrometric chart and various architectural strategies for further exploitation of adaptive ventilation according to different climates, were obtained. The best adaptive ventilation comfort performance was observed for Zahedan city with 17.4% (1524 hours per year) and the weakest performance was observed for Yasuj city with 9.2% (804 hours). Moreover, to use natural ventilation, solutions were suggested for using awnings and window orientation, methods for creating chimney ventilation and cross ventilation, roof, veranda, and covered courtyard for passive comfort.
