Buildings constructed in the 1960s–1980s constitute a significant part of the housing stock in Ukraine and other European countries. However, most buildings from this period do not meet energy efficiency requirements or modern urban planning and sanitary standards.

Based on the analysis, the main objectives and the expected results of the social sphere fixed capital modernization are identified.
