Currently, reducing energy consumption, preventing environmental pollution and using recyclable materials are being intensively considered in facade design. These factors are especially important in multi-storey glass facades because of the high-energy loads resulting from heating, cooling and ventilating systems. Reduction of these loads will be possible as a result of attention to climatic facade design. Such a facade will be able to protect the building by controlling external effects. Double-skin glass facades have been developed as the result of such an approach. They are formed by installing solar control devices in the cavity between two glass skins. In such facades, heat losses are relatively small. The system allows windows to be opened, even on the top storey of the building. Hence the ventilation is provided by fresh air, resulting in the need for less energy to run the mechanical system.
