Method of calculating actual heat losses at the existing construction facilities

This article is dedicated to the issues of energy saving, in particular to the problems of improving energy efficiency of modern buildings by experimental studies of thermo physical properties (TPP) of materials in order to eliminate excessive heat losses through building envelope. Based on the analysis of the existing methods of determining the materials’ TPP, the authors developed an algorithm to determine the actual heat losses of a facility under study. Operation of an installation for determining the TPP (heat transfer coefficient, thermal resistance and specific heat characteristics) of the facility under study is described. The formulas required for the calculation of TPP are given. Experimental results of the study are provided. Main advantages of the developed installation are described.
