Effects of External Louvers on Solar Heat Gain and Energy Consumption of an Office Building in Different Climates of Iran

In recent decades, the louvers have been commonly used as shading devices in office buildings. This study is conducted in order to determine the optimum louver’s external angle of an office building from the aspect of solar heat gain and annual energy consumption. In this respect, a sample building with louvers shading devices in the south, east, and west facades was selected, and simulations were conducted by means of the DesignBuilder software...
