The sources of energy are finite and are often found in unstable regions of the world, and we cannot assume at present that heat will be cheaper. Hence, and not only for these reasons, the issues of heat losses from buildings must be addressed. The paper investigates the issues of heat losses from buildings and analyses the benefits of thermal insulation of buildings. The thermal insulation of a building reduces the leakage of heat during the heating season and brings about savings in heat consumption amounting to tens of percent. In addition, when a building is insulated, the heating season may start later and end earlier. Typical thermal insulation technical modifications include the insulation of external walls, replacement of windows, roof insulation, insulation of the ceiling under the attic and above the cellar. Reducing the leakage of heat will reduce its consumption in heating and thus also cuts down air pollution with emissions produced by heating. The benefits of thermal insulation are in the economic, as well as technical sphere of building operation. The study compares the structure of heat losses and heat gains of apartment buildings from the 1970s, both in the insulated and uninsulated version, with houses complying with the current required standards and houses complying with the current recommended standards.
