Abstract :
    The issue of the global energy crisis has focused on optimizing energy consumption in buildings, especially residential and residential, as a new approach. On the other hand, the use of passive cooling systems has a high impact on energy consumption. The use of daylight in the field of architecture is also an important factor in creating visual comfort and distributing natural light. Proper use of building facades as an architectural element that interacts with the exterior of the building and the presence of shades on the exterior of the building can be effective in reducing energy consumption and in providing optimal daylight for users. The purpose of this study is to provide practical solutions to make better use of daylight in order to provide users with visual comfort and reduce cooling energy consumption in residential spaces using external shades for the openings. Therefore, this paper investigates the effect of different types of canopies (horizontal, vertical, three-way, Louvre) on the exterior walls of the building as an independent variable on how much energy and daylight is used to enter the building as dependent variables. Investigations in the hot and humid climates of Bandar Abbas and in the hot seasons of the year that require more cooling have been carried out using library studies, climate analysis using Climate Consultant 5.4 software as well as simulations in Design Builder software. Finally, the results of the simulations show that, for the western wall pop-ups, the Louvre, and the eastern wall, the frame-shaped canopies can largely meet the objectives of the research in terms of both energy consumption and the equilibrium distribution of daylight in space.
