Abstract
This research was conducted to assess the performance of horizontal shading device on the building shadow area in two different climates of Iran. The case studies were two holy shrines in Shiraz and Savadkouh (semi arid climate and humid and moderate climate respectively) and were prioritized by Analytical Hierarchy Process weights. The solar angles and shadow area were derived and compared accordingly. The results showed that the shadow on the beneath wall of the lower latitude case study (Shiraz: 29°33′N) was 48.21% in January and 100% in July, and the parallel ratio for Savadkouh was 26.1% in January and 97.22% in July. Through comparison of the monthly shadow area on wall in July with that in January in both climates, the Shiraz and Savadkouh ratios were found to be 2.78 and 4.79, respectively, which indicated that shadow areas in summer were more than those in winter. Therefore, the shadow could cause more outdoor thermal comfort in winter and summer in both climates.
