Abstract

In the article the problems of the modernization (renovation) of dwelling-houses are discussed according juridical, social, ecological, technical-technological and economical aspects. When the decision to renovate the dwelling-house is made, first the juridical problems have to be solved. These problems involve planning of investment project, social problems of individual flat dwellers and the infringement of their rights. In many cases the modernization of dwelling-house is suspended because of the improper solution of juridical and social questions. Other renovation problems are: unqualified house energy audit making, technically unsound heating insulation and architecture of house facade decisions, and final approximation all decisions. The house energy audit is performed before modernization, the theoretical heat transfer coefficient and resistance of external walls are calculated and heat transfer coefficient according the standard STR 2.05.01:2013 “Design of the Energy Performance of Buildings” is noted. Designing a technical project for the multi-apartment house modernization, it is necessary to make a precise evaluation of heat loss before and after the modernization, to calculate the modernization workload and the expected decrease of heat consumption. Performing the modernization works constant and qualified supervision must be performed. Actually home-owners do not have any economic benefit because of the rising heat selling prices. But after the modernization the living conditions are improved, heat energy is saved state-wide, and environmental pollution is reduced.
