The aim of the research is to analyze heat losses through the outward enclosing constructions of the buildings of the first mass series before and after the sanitation. As measures for sanitation, walls, ceilings, attic and ground floors were chosen for the insulation, as well as replacement of old wooden windows in polyvinylchloride windows with double-glazed pane, replacement of wooden entrance doors in warmed metal ones. Materials for insulation are chosen in accordance with the climatic features of Arkhangelsk. The calculations were carried out in accordance with the requirements of modern regulatory documents. Based on the obtained data, as well as the duration of the heating period and the current tariff, the amount of savings in thermal energy is determined. This information allows to conclude that the proposed activities are energy-efficient. Savings on heating after sanation: for «Stalin’s serie», will be 272 thousand rubles, for «Khrushchev’s serie» - about 410 thousand rubles and for «Brezhnev’s serie» - 930 thousand rubles in year.
