摘要：

The article deals with the engineering technique for determining the heating time of building envelope constructions in the conditions of intermittent heating. The authors present the results of the calculation of the temperature field in the single-layer claydit outer wall, resulting from the exact solution of nonstandard heat conduction problem. To estimate the time of heating and thermal energy consumption for heating the multilayer envelope constructions, an approximate analytical method is developed, the error of which is determined by comparing with the exact solution for a single-layer wall. With the help of this method, it is conducted the analysis of dynamic property and energy consumption for heating of claydit external wall, insulated from the inside with the help of extruded polystyrene foam.
