The building envelope plays an important role in the thermal load of the building as a separator of interior and exterior environment. This part of the building as the most important source of light and solar energy, has an significant impact on heating and cooling, intentional and unintentional ventilation, noise control, quality of design and execution and aesthetic dimensions, compared to other building components.
The facade of a building is a complex interface between the interior of the building and the external environment that can function as a protective or monitoring element against severe fluctuations of the external environment.
The use of double skin facades (DSF) as a suitable solution to create an efficient thermal wall in the building is significant, and since its performance is climate dependent, so full understanding of the behavior and parameters affecting the design of DSF with Considering climatic conditions is one of the objectives of this research. In order to evaluate the efficiency of the double skin facade idea in the climate of Zanjan, a building called the Cultural Book Campus was simulated in different options with and without a double skin facade and its energy performance was simulated by Grasshopper software. Then, the different modes of the double skin facade were evaluated in terms of heat load, and the appropriate double skin facade was selected. Finally, the selected double skin facade has been studied for further studies to improve the thermal behavior of the building.
Based on the simulation results, it can be said that according to the applied inputs, the amount of energy consumption of the building with double skin facade has been reduced by 28.28% compared to the model without double skin facade and 21.43% decrease compared to the base model of corridor double skin facade. Has been found and the highest amount of building load reduction is related to building cooling, which is about 40% reduction in building cooling load has been observed. In general, the amount of energy consumption of the building has increased from about 116 kWh per square meter to 83 kWh per square meter. However, paying attention to other important factors of the facade such as vents, shading components and the ratio of the transparent surface to the walls and the material of the glass, etc. will play an effective role in improving the heat load of the building. The results show that the use of windows with lower solar penetration and movable canopies have the greatest impact on improving the thermal performance of the double-skin facade and reducing the thermal load.
