Abstract:
The purpose of the article is to analyze individual measures for the thermal modernization of buildings and determine the sequence of the implementation of such measures, allowing to obtain results in the shortest possible time with the maximum possible result. The actual state of the housing stock of Ukrainian settlements in the pre-war period did not meet the EU requirements for energy efficiency. After massive damage to residential buildings as result of russian aggression, their restoration becomes an urgent task. The article proposes to restore the settlements of Ukraine that suffered from the armed russian aggression by performing repair work with simultaneous thermal modernization of residential buildings. The content of the concepts of «traditional and deep thermal modernization of residential buildings» is examined and it is proposed to focus on traditional modernization, which involves a set of works on replacing windows and doors with energy-efficient ones, insulation of enclosing building structures (facades, basement, roof and basement floors), thermal modernization of engineering heating systems and hot heat supply (thermal insulation of intra-house pipelines, installation of individual heat points, balancing of heating systems, installation of apartment thermostats), as well as installation of individual ventilation devices with the possibility of heat recovery. On a conditional example, two options for performing works on mass thermal modernization in conditions of scarcity of investment resources are considered: the first is the implementation of works on thermal modernization of individual houses «turnkey»; the second is the implementation in all houses of only those measures that have the shortest payback periods and the implementation of which provides the best energy savings. A computing with use of a conditional example showed that the second option allows saving energy resources by 35% more than in the first option. According to the results of the study, the following sequence of thermal modernization works is proposed: priority measures (replacement of windows and doors), modernization of engineering heating systems, installation of individual ventilation systems, insulation of enclosing structures.

Keywords: restoration of settlements, thermal modernization of buildings, sequence of thermal modernization of buildings, efficiency of thermal modernization.
