Individual housing construction in the Krasnoyarsk Territory is actively developing. Rising housing prices in multi-storey buildings, increasing building density, and socio-demographic factors are increasing the popularity of individual construction. Technologies for such construction imply the widespread use of available local building materials, in particular wood. During the study, the designs of private houses in the settlement - the regional center of the Krasnoyarsk Territory - were analyzed. It was found that 90% of the sample examined were houses built from timber. Using simulation modeling methods, the actual thermal resistance of the enclosing structure made of timber with a cross-section of 0.15×0.15 m was determined. The calculated value was compared with the standard resistance indicator of the enclosing structure, taking into account energy saving standards. The Elcut solid modeling system was used in the work. The required heat flow power to maintain stationary heat transfer conditions was determined. It has been established that the design enclosing structure does not provide the required thermal resistance taking into account energy saving standards. It is necessary to consider a multilayer enclosing structure and increase the design resistance by insulating the outer surface of the wall with heat-insulating materials.

“…Basically, the work sets the task of improving the technology of building materials -substantiating the possibility of partial replacement of mineral components with organic ones to improve the thermal performance of buildings. The thermal efficiency of buildings made of materials based on wood-mineral composites depends on many factors, the design solutions used, the shape and size of the blocks, joint materials, and the presence of thermal inhomogeneities [12,13]. In [14], the authors carried out mathematical modeling of heat transfer phenomena in the wall of a building.…”

The involvement of recycled wood resources and low-quality wood in the processing provides an active source of raw materials for the construction industry. Environmentally friendly building materials in the form of wood-mineral composites (WMC) help recycle this waste and help conserve natural resources. The study examined the thermal performance of enclosing structures in the form of a frame wall filled with mineral wool, walls made of aerated concrete blocks and stands made of WMC. The purpose of the work was to determine the thermal regime of enclosing structures under stationary and non-stationary thermal conditions. The unsteady mode was created by simulating the generation of thermal energy for 10 hours a day. The mode corresponds as closely as possible to the actual operating conditions of an individual housing construction project, provided that it is heated by a solid fuel boiler or stove with periodic generation of thermal energy. The total simulation time is 5 days. It has been established that in a stationary thermal mode, all considered structures comply with sanitary and hygienic requirements and heat conservation standards.
