Abstract

The study presents a comparative analysis of technical solutions and technologies for energy-efficient capital repairs of apartment buildings. The purpose of the study is to identify technical solutions and technologies during the overhaul of structural elements of an apartment building that ensure the most effective reduction of heat losses and consumption. The methodological approaches of the study are based on a statistical analysis of the data on the results of major repairs in the Russian Federation. According to the results of the study, it was found that when planning major repairs, it is necessary to choose a set of technical solutions and technologies that together contribute to reducing energy consumption during work and achieving the most significant results in increasing the energy efficiency class of a residential building based on a comparative assessment of alternative options. The analysis showed that with the introduction of modern energy-saving technologies, the overhaul of apartment buildings can increase the level of energy efficiency for a minimum period of operation (for a quarter of a century) before the next major overhaul, ensuring equal conditions of energy comfort with new generation buildings (modern construction), which as a result improves the quality of life of citizens and accelerates the economic growth of the country.
