Energy efficient design of building facade, inspired by human skin

Much of the energy consumed is used to provide comfortable conditions in buildings. Windows (all transparent walls) is one of the weakest points in wasting energy. In this study, using the characteristics of human skin as a protective layer and interface between the inside and outside of the body, an attempt is made to improve the transparent walls performance of the building facade. Simultaneously, the process of question-answering is articulated, and the characteristics of this natural pattern are discovered. Then, human skin traits are applied to enhance the diverse functions of facades. Finally, according to the characteristics of the skin, among more than 15 primary etudes, a vertical shading system is presented that can control the incoming radiation. The design is evaluated in two modes, controlled by temperature and controlled by the intensity of sunlight. The results show that more than 10% of energy consumption is reduced with movable shading systems. A separate study of energy consumption for cooling, heating, and lighting makes it more reasonable to use a temperature-controlled shading system, which can save 23% to 25% of the annual cost.
