Review article

In the absence of design information on heating systems for most reconstructed pre-revolutionary buildings, an important role is played by the correct determination of the thermal characteristics of the enclosing structures when calculating the loads on heating systems. In practice, the thermal conductivity coefficients in the calculations are decided upon without proper justification, which leads to an incorrect assessment of the building heat consumption and efficiency reduction of systems ensuring the microclimate and energy saving measures. The author presents the data of experiment on the study of the thermal conductivity of brick materials under conditions of stationary heat transfer.
