The study presents tools for calculating the consumption of fuel and energy resources when carrying out major repairs of a multi-apartment residential building. The purpose of the study is to reduce energy consumption during the work phase and increase the efficiency of the capital construction project. The methodological approaches of the study are based on calculation, analysis and comparison of the obtained values of consumption of fuel and energy resources when carrying out major repairs of an apartment building. Based on the results of the study, it was established that the structure of energy costs during major repairs is determined to a greater extent by the «machinery and mechanisms» consumer group, which may include a different number of subgroups. Analysis of the calculated values of consumption of fuel and energy resources showed that significant energy consumption during repair work is due to the mechanization of labor using construction machines (truck crane, truck) and equipment (roof burner, combined sprayer, etc.).
