Abstract—The intelligent facade reduces the primary energy consumption of a building, use of natural, renewable energy sources, such as solar radiation, air flows and creates a comfortable environment for the occupants. For that reason ecological intelligent facade can be defined as changing light and weather conditions using self- regulating thermal protection and solar control measures. Considering that energy consumption is one of the foremost issues of our time, energysaving measures have become of vital importance. This particularly applies to buildings, since the amount of nonrenewable energy resources they consume is considerably higher than in other areas of consumption. The energy consumption level of a building is contingent on that building’s specific structure as well as the thermal properties of the building and its environment, the climatic conditions prevailing at the building’s location, the times when the building is used, and the specifications of the systems employed for heating and cooling. A building skin design tuned to energy-efficiency criteria allows both conservation and generation of energy. In addition, by employing renewable energy resources for heating, cooling, and lighting, it contributes to reduced use of depletable energy resources, accounting for the responsibility towards the global community. Energy-efficient facade design, which starts with decisions at a building’s initial design stage, directly affects a whole array of factors, including the choice of system. This study focuses on those parameters and alternatives for energy-efficient building skin design that support the concept of ecological building, and presents practical examples for feasible systems. In this study ecological building skins will be classified as single skin facades, double skin facades (Corridor facades, building high double skin facades, building high controllable double skin facades, box windows) and combined facades.
