Increasing the energy efficiency of wooden house construction

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.
