Determining the range of thermal comfort in the outdoor space is complicated, and since the presence of thermal comfort helps more people to be in the outdoor space, it is important. In the current research, it has been tried to determine the thermal comfort limit of people in the outdoor space of traditional and restored buildings in the hot and dry climate of Yazd city. For this purpose, a field monitoring was carried out in the hot season of the five central courtyards of the Yazd faculty of Art and Architecture as buildings that have been changed from residential to educational use, which includes the measurement of climatic information at the same time as the completion of 389 thermal comfort questionnaires by the students of the faculty; Then, with the help of Ray Man and SPSS software, the obtained information was analyzed and after checking the linear regression charts, the range of thermal comfort for people in the central courtyards of the faculty as a microclimate in the hot and dry area of ​​Yazd city between the range of 16.5-28 degrees Celsius based on the Physiologically Equivalent Temperature index (PET) was obtained. Due to the fact that the combination of climatic and geographical factors for each specific region will lead to a different understanding of the thermal comfort conditions for the people of that community, this comfort range is different from the comfort ranges in other regions that have been determined in numerous researches. From the comparison of the studied yards, it was found that the more the yard has a height-to-width ratio and the more enclosed it is, the more shade it will receive and, finally,more thermal comfort during the day and night for the hot days of the year.
