Abstract: Energy today as one of the major factors in the formation and development of industrial societies known. Reduction of energy consumption requires a new solution approach for sustainable architecture .So the choice of double skin facade is as a way to efficiently use energy resources. The method of research in this paper was based on data collected in the form of Case Study Method. This paper calculates the energy saving by Double Skin Façade in two case studies, ICICI Tower and Jet Airway H.Q, in Mumbai. The aim of the research was to evaluate the total quantity heat gain in two case studies according to solar intensity and surface area of building as a reduction in energy consumption and an increase in occupant comfort. Double Skin Facade and combining it with an HVAC system that besides the positive aspects of aesthetic studies and examples of actual results in 30% savings in energy consumption. Additionally, natural ventilation, building dependence natural light plays an important role in the reduction of noise reduction and Resistance to wind energy.
