The technical and economic basis of facade systems

The problem of energy saving and increase of energy efficiency of buildings by improvement of constructive solutions of facade systems is relevant. The complex assessment of indicators of various types of façade systems is absent at present. The object of research is the facade of the apartment house projected as a part of a housing estate for a cold Russian climate (HDD = 7649 K*days/year). Two types of modern facade systems, such as the facade thermal insulation composite system with external mortar layers and the ventilated facade system are considered. The comparative analysis of thermal performance, economic and operational characteristics of these facade systems is carried out in this article. Following the results of the technical and economic analysis of these facade systems the conclusion is drawn that facade thermal insulation composite systems with external mortar layers are more reliable and economically reasonable systems. It opens great opportunities of their further studying for the purpose of their effective application in modern construction.
