OPTIMIZATION OF EXTERNAL WALL INSULATION IN PRIVATE BUILDINGS

Abstract

The paper deals with minimization of cost expenses on insulation and operation of buildings. The thickness of thermal insulation of enclosure structures are calculated using the proposed quadratic equation with cost parameters, such as heat production, heat insulation, facades, heating system, and cost expenses. The dynamics of the consumer price index and the cost of energy carriers for the population are analyzed in order to obtain the necessary set of initial data. The study is conducted on the example of Moscow and the Moscow region. Newly erected buildings, both with single-layer and multi-layer walls are considered as well as the building insulation at a stage of repair or reconstruction. The obtained optimum values of the heat resistance vary several times, both significantly lower and higher than the standard values depending on the specific task.
