The thermal<br />functions of the building can be separated and studied in two parts: walls and transparent<br />walls. It seems that in hot and dry climates, due to the intensity of the received radiation,<br />it is very important to control the incoming radiation from the window. For this purpose<br />and to make a comparative comparison, a four-story commercial-office building was<br />selected in the hot and dry climate of Kashan City. Therefore, the thermal performance<br />and the amount of energy consumption of this building in the four modes of the basic<br />mode, modified walls, modified transparent walls with the help of shading devices, and<br />the comprehensive mode (modified walls and modified transparent walls) is examined.<br />The results of this research show that modification in walls reduces the amount of primary<br />energy consumption by more than 19%, in transparent walls by more than 20%, and in the<br />comprehensive mode by more than 27%. This can reduce the annual cost by more than<br />22% in walls, more than 24% in transparent walls, and more than 33% in comprehensive<br />mode. https://www.ijumes.com/article_703253_6baeaded556207384420a3a68b8cab7f.pdf
