In arid climate, it can improve thermal comfort through natural ventilation. With the aim of recognizing the impact of this masterpiece on thermal comfort, this research examined the effect of wind on summer ambient temperature by employing PMV. To this end, wind catchers &nbsp;of Salehi&#39;s House was selected. To investigate the function of wind catchers &nbsp;in Shiraz, enjoying a semi-arid climate, temperature, humidity and wind were measured by data logger TA120 between 9:00 to 16:00. Afterwards, PMV and PPD were obtained through Fanger Formula. The results based on wind and in the case when the wind catcher and openings are close and open showed that the amount of thermal comfort was directly related to the amount of wind coming from the wind tower. It was also concluded that the average ambient temperature in ground was declined by 0.8 &deg;C and in the first floor it was declined by 0.9&deg;C.</div> Thermal Comfort, Wind Catcher, Wind, Natural Ventilation, PMV. 213 222 http://ijaup.iust.ac.ir/browse.php?a_code=A-11-1332-1&slc_lang=en&sid=1 M.
