Abstract :

Introduction: The presence of computers and working equipments in official and educational buildings caused the increasing of internal temperature and using glass façade vastly has caused more negative effects of this problem. The question is how to reach to the comfort degree of internal temperature without using excessive energy at the same time of benefitting the visual beauty of the glass façade. The aim of this study is to evaluate the effects of the quantity of layers of the internal and external of double skin façade on energy consumption. Methods of study: The method of this research is based on causal modeling and simulation. The used equipment was the software of thermostatic simulator called “Design Builder”. In order to reach to the lowest level of energy consumption, different modes of the layers in the double skin façade were analyzed by using the design builder software. Findings: The results revealed that in double skin facades, changes in the number of inner layer are efficient in reducing energy consumption, while the outer layer of glazing does not play any role. Using the double skin facade in southern side is more effective because of the sun radiation on this side. Results: Due to the heating and cooling degree days in Tehran which is equal to 1610 and 1435°C respectively, in the summer, habitability and comfort level of residents were demanded mostly. So in the summer, change in the number of inner layers is more effective than the outer layer.
