Оптимізація інженерно-будівельних рішень при термомодернізації житлових будівель перших масових серій забудови

Abstract

The results of the presented research are conclusions based on the results of numerical modeling of heat energy transfer in multilayer brick external walls in multi-story residential buildings of the first mass series of construction. The obtained topology of temperature field contours is presented and analyzed, the temperature values on the outer and inner surfaces of the walls are determined, and the influence of the thickness of the insulation on the nature of the distribution of thermal energy in the thickness of the protective brick wall is determined. Conclusions are drawn based on the results of the study. It was also stated that it is possible to use a reuse project with a 150 mm insulation thickness, in compliance with the requirements of the DBN for thermal modernization 2021. It is recommended that in major renovation projects aimed at thermal modernization, focus on achieving energy efficiency class "C".
