Impact of external shading devices on the amount of energy consumption for cooling in a mid-rise residential building in a hot-dry climate: The case of Ahvaz

Abstract :
Buildings all around the world account for the highest energy consumption. Thus, architectural decisions have the most critical role in reducing energy consumption in buildings design. Nowadays, the use of glazed facades is increasing in modern buildings all over the world. These glazed facades have some profits such as improving the daylight availability in interior spaces of the building, make better external views, and create fantastic architectural designs. However, this amount of using glazed facades in buildings causes excessive heat in interior spaces of the building, which is becoming a significant problem in hot climates. Therefore, among various active and passive design strategies, external shadings can be considered as one of the methods used to protect the building against direct sunlight that causes a considerable amount of heat. In the present study, the amount of reduction in energy consumption for cooling is calculated using external shading devices. In this study, the comparison of the energy-saving capability of horizontal and vertical shadings evaluated in a residential building in the hot and dry region of Iran. The energy consumption of vertical shadings at 0, 45 degrees to east, 45 degrees to the west and 60 degrees, and horizontal shading at 0, 45 and 60 degrees on the south façade compared with the base condition (no shading devices), at four hottest months of the year. In this study, the Design-Builder software used as simulation software. The condition of the presence of horizontal shadings at 60 degrees compared to other modes have the maximum energy saving potential, as results show. These shadings can lessen energy consumption for cooling up to 13 percent.
