Considers the modern building envelope construction with outside skin used as a sun shields. Such a constriction is often used for buildings with low energy consumption. A number of factors besides sun radiation influencing on the performance of facade system in general and every certain parts and elements throughout the entire period of building operation. Subject: multilayer and double skin building facades and sun screens located on their surfaces. Including, dual-use facades combining functions of the sun screen and sub construction for the placement of photovoltaic cells. Materials and methods: the main method was an estimation the aerodynamic and air-thermal characteristics of a double skin façade. Was considered a construction with combined function of a sun shield. The method was previously used in evaluation of the air-thermal regime of hinged facade systems of buildings for cold period of a year. The general approach was advanced and verified by the results of full-scale tests of building facades in the warm period of the year. Results: indicates great influence of air and thermal conditions of air gap in double skin and similar construction facades on performance of façade system in general and on every certain part of it. Conclusions: the construction of complex facade systems with the use of up to date technologies requires additional study of the air-thermal conditions of the air gap between the main facade of the building and its second skin or sun screen. Ignoring the operational features of active sun shields under extreme loads can lead to a decrease in the equipment functionality and its premature failure.
