The subject of the article was focused on aspects of energy-saving construction, and the main determinant was the heat transfer coefficient U, which determines the ability of heat energy to pass through building partitions. The scope of the article included conducting research for an existing two-story building before thermal modernization and after thermal modernization works in order to determine the economic and ecological benefits resulting fromthe works carried out. Thermal modernization works included: insulating external partitions with graphite polystyrene with a thermal conductivity coefficient of λ = 0.30 W/(m•K) and a layer thickness of 20 cm, replacing the coal boiler with a dual-function gas boiler with a hot water heater utility water, replacement of cast iron radiators with three-plate steel radiators and a ladder radiator in the bathroom, replacement ofwooden double-glazedwindowswith a heat transfer coefficient Uw = 2.60W/(m2•K)withwooden-aluminumwindowswith a heat transfer coefficient Uw = 0.95W/(m2•K) with a two-chamber glass unit.
