Abstract :

Background and Objective: Double skin facades (DSF) are an interesting and important architectural element in buildings because they are very visually appealing and at the same time can perform better than single skin facades.  Double skin facades must be properly designed and implemented, otherwise their potential benefits may be lost. For this reason, the physical processes occurring in a double skin facade must be well understood and predicted. However, they are very dynamic and static. The aim of the current research is to analyze the double skin facade moving in the efficiency of energy consumption in residential buildings in Tabriz city. Material and Methodology: In this research, the analytical descriptive method as well as numerical equations, Design Builder software, Converge and sensitivity analysis were used. Findings: The results showed that for the double skinned facade in cold seasons, by blocking the top and bottom of the double skinned facade, the air trapped between the double skinned facades is functional insulation and energy loss is reduced. Also, in hot seasons, by leaving the top and bottom of the skin open and creating air flow between the double skin, the heat transfer from the building increases and as a result, the temperature inside it decreases. Discussion and Conclusion: The results of numerical solution of computational fluid dynamics equations in Design Builder software showed that using this method in Tabriz city, the annual cooling load is reduced by 45% and the annual heating load is reduced by 5%.
