Refinement of thermal engineering calculations results taking into account actual materials characteristics

Abstract

The article presents the laboratory studies results of building materials thermophysical characteristics used in the construction of experimental wooden buildings. In the framework of laboratory experiments, the thermal conductivity and humidity of structural and thermal insulation materials samples were evaluated. The analysis and comparison of the results obtained with the characteristics of the materials declared by the manufacturers and in the reference data is carried out. The results of thermal engineering calculation refinement of the of the enclosing structures of experimental wooden buildings, taking into account the results of laboratory studies of the thermophysical characteristics of building materials used in construction, are presented. The thermal engineering calculation of the enclosing structures of the frame part of experimental buildings has been refined taking into account the actual thermal conductivity of building materials. The influence of the actual thermophysical characteristics of building materials on the results of thermal engineering calculation in comparison with the design values was evaluated. Further directions of research are presented in terms of the influence of cold bridges and inhomogeneities of structures on the thermal characteristics of the thermal contour of the building.

“…In addition, despite the consistency of the results presented with experiments and previous work [13], further research on this topic is advisable, as the number of samples studied is small. From a practical point of view, the results of research in the affected area can contribute to the implementation of specific projects in accordance with sustainable development criteria [14][15][16][17][18][19][20].…”
