During the energy crisis and the world’s attention to optimal energy consumption, especially in buildings, the walls of the buildings became one of the most important parts of the design process. In the first step, air locking and isolation of the walls were important in order to prevent the loss of energy. In the next steps, the need to get proper solar radiation in cold areas and the existence of a tool to prevent the entry of solar radiation in hot areas was raised. The aim of this paper is to investigate the effect of the shading tool location and the optimal combination of glass layers in double skin facade in the warm and humid climate of Iran. The methodology for achieving this goal is to use computer simulations (Fluent software). In this study, different configurations of double skin facade have been investigated. During these surveys, the structure has been considered optimally in the Kish Climate Zone. Three different areas were investigated for the establishment of shaders; the findings of this study are presented as temperature and air flow diagrams and contours. The results of this research show that the most suitable place for the establishment of the shadow tool is the interior and back of the double skin façade.  It was also found that the proper type of double skin facade, in order to prevent the optimum from increasing the internal temperature, includes a glass layer in the outer shell and a window with a double-glazed glass in the inner shell. In this paper, the “simulation and modeling research” method has been used. In this paper, the “simulation and modeling research” method has been used. In the software simulation and numerical analysis sections, the type of quantitative research is “analytic” research method and results are obtained based on “induction”.
