The Impact of Wind on Ambient Temperature and Thermal Comfort Through Wind Catcher By Employing Pmv-A Case of Salehi'S House in Shiraz, Iran

Wind catchers in arid climates are one of the most prominent masterpieces of iranian traditional architecture which 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 and predicted mean vote (pmv). to this end, wind catchers of salehi's house in shiraz case in arid climate and the ambient temperature, humidity and wind speed were measured by data logger ta120 between 9:00 to 16:00 in summer for calculating pmv and predicted percentage of dissatisfied (ppd) through fanger formula. the results through open or close wind catcher and openings showed that the thermal comfort was directly related to the amount of wind coming from the wind catcher. it was also concluded that the average ambient temperature in ground was declined by 0.8 °c and in the first floor it was declined by 0.9°c.
