Abstract
In this paper the results of mathematical provement of economical optimal thermal resistance of a building wall are presented at condition of both heat energy and thermal renewal cost change on future. There are presented comparation of technical and economical indexes at external walls renewal at the different characteristics of enclosure constructions. Purpose is to analyze the technical and economic factors that determine economic feasibility insulation of external walls subject to changes in the cost of heat and renewal in future. An allocation of individual components cost of the building facade insulation by insulating materials is presented. The dependence of different financial costs on the thickness of the insulation provided changes in the cost of heat and renewal in future is determinated. It is determinated that the best insulation material from five considered for a given output data is polystyrene; 15-year term optimal thermal resistance increases almost 1.4 times; there is an objective need for periodic revision Ropt value and its legal approval, because it has a dynamic property.
