This paper will survey the various types of double skin façades and their features, functioning followed by a review of examples, both constructed and proposed. The building facade plays an important role in achieving energy conservation. The aim of this report is to describe the concept of Double Skin Façades based on different sources of literature. Its complexity and adaptability to different climatic conditions increase the need for careful design. Since the construction types can differ from one location to another, it is obvious that the comparison of different literature sources is not always relevant. Since the concept of Double Skin Facades is complicated and its use and function affects different parameters of the building, the literature studied is from different fields. as a conclusion the designed system is crucial for the performance of buildings. Due to technological advances, transparency and the use of glass has become an attractive envelope option in architectural design. Designing buildings with all glass facades provide external views and potential for an excellent level of natural light as well and natural ventilation.
