The study analyzes the thermal protection of a building located in Karaganda, Republic of Kazakhstan, using the ANSYS software, taking into account the region’s cold climate. A newly developed energy-efficient threelayer panel made of highly porous polystyrene concrete was proposed, and its thermal characteristics were compared with those of traditional wall constructions made of solid and hollow ceramic bricks. As a result, the proposed new construction proved to be effective, with a thermal resistance value 8.8% and 5.6% higher than that of traditional constructions. Moreover, the analysis of specific characteristics and energy loads of the wall constructions demonstrated that the new three-layer panel made of highly porous polystyrene concrete is 2.5% more efficient than traditional solutions. Additionally, the proposed construction can reduce construction costs by up to 15% compared to conventional options. The findings of this study can be utilized by scientific and technical centers in the design or renovation of buildings.
