  The utilization of buildings contributes to approximately one-third of global energy consumption and a similar share of greenhouse gas emissions. In Iran, the buildings' energy consumption is more than 40% of the total energy consumption. Meanwhile, the environment, saving on fossil fuels, and sustainable development have become very important and common topics in the international arena. So, the building shell plays an important role as the outermost layer of the building, which is mostly connected to environmental factors. This article designs and evaluates the efficiency of the smart shading that prevents unwanted penetration of sunlight in the warm months of the year and allows light to enter the space in the cold months of the year. With the glance aesthetic view, Iranian geometry has been used to create these shading to achieve this beauty. Computer simulation and analysis and library resources are the methods used in this study. In this regard, an analysis sample with dimensions of 4 meters wide, 6 meters long, and 3.2 meters high as a part of office space for the shading were designed. And its effect on indoor lighting in the warm season was analyzed in VELUX Daylight Visualizer software. These shadings move and change direction according to the rotation of the sun. The analysis shows that in hot weather of the year, these shadings can reduce the brightness of the interior space by one-third and reduce the cooling load and keep the light intensity (lux) close to the standard of office space (300 lux). Furthermore, in the cold season of the year, the opening of these shadings is allowed light to enter. Manuscript profile
