Double Skin Facade & Its Impact on Energy Reduction

Society and the infrastructure are significantly dependent on energy and due to rise in the energy demands for the proper functioning of the building, there is a huge load on the available limited resources around. Therefore, the concept of sustainability is introduced to promote the use of natural renewable resources by applying the various techniques and practices. So, various solutions have come up to reduce the energy consumption of building in order to step towards sustainability approach. By using the double skin facade (DSF) in buildings external facade, the available energy resources can be used in more efficient way. The external facade of building has a major role to play in the energy consumption, performance and interior environment of the building. In buildings where exterior glazing is used on large scale the Double skin facade is the appropriate solution that can control solar heat gain, can reduce the cooling and heating demand by reducing the heat loss and also can minimize the wind and acoustic effects. Therefore, the aim of this paper would be to understand the basic functionality of double skin facade, its impact on interior environment of the building and the level of energy reduction achieved by double skin facade.
