Abstract
The layer of the building as a separator of the interior and exterior environments plays an important role in thermal behavior of the building. Compared to the other parts of building, the façade has a significant effect in terms of solar heat gain, day lighting, ventilation, infiltration, thermal load control, noise control, design quality and aesthetic dimensions.
New concepts of façade design; turned the building façade to a barrier between the interior and exterior environments. One of these concepts is double skin façade. To assess the performance of double skin façade in the climate of Tehran, an office building is modeled both with and without double skin façade with the building energy simulation program E-QUEST. In these simulations, the effect of façade layering, transparency and orientation on energy demand of HVAC system have been compared and contrasted. The results show that the energy demand of HVAC system reduces about 16 to 20 % by using a double skin façade compared to a single skin façade. However, to improve the energy performance of the façade, one has to consider other important design parameters in façade design such as ventilation, control strategy, shading devices, etc.
