The requirements to a desired level of thermal protection of outer walls of buildings have been analysed. The relation between such requirements and social factors of a country was shown. Comparison data regarding heat releasing surface area of outer walls and windows and heat losses per person have been received for variable residential density of apartments. The authors have shown international practices and the needs for transition to construction of buildings with a higher level of thermal protection of outer walls. Since cold generation is 3-5 times as expensive as heat generation for many buildings, the transition was made from ventilation of the naturally driven type to controlled and mechanical one providing heat recovery of exhaust air. It was suggested that problem of energy-saving in the sector of construction and housing and communal services could be solved providing a desired life of outer walls and costs of current and major repairs required for projected lifetime of a building.
