The purpose of this article is to analyze the efficiency of management of an apartment building in the context of energy efficiency. The article describes the conduct of an energy audit for apartment buildings, which allows a thorough assessment of this problem and identify optimal ways to save energy resources by apartment buildings. Energy audit is a special examination of residential buildings or enterprises, conducted by specialized specialists in energy certification of buildings to determine their technical condition and energy efficiency. Methodology. Within the framework of this article, the results of a sociological survey conducted among the heads of condominiums to analyze the level of their interest in the implementation of energy efficiency measures were analyzed. The value of the cost of 1 apartment for the implementation of the energy modernization project is calculated. Currently, "energy efficiency" and "energy saving" are extremely popular in Ukraine, due to the following: increasing the cost of energy resources;limited financial capacity of vulnerable groups to pay for services. Results of the survey showed an insufficient level of implementation of energy-saving technologies, although the level of interest of apartment building heads is very high. The development of energy efficiency programs for an apartment building is carried out not only taking into account the necessary priority measures, but also based on the financial capacity of the co-owners of the apartment building. The reason for the insufficient implementation of energy saving measures is the insufficient financial capacity of co-owners and, as a consequence, the apartment buildings themselves. State support for the implementation of energy efficiency in the management of apartment buildings has been studied in detail. It is concluded that large-scale involvement of apartment buildings in the implementation of energy efficiency programs is constrained by the following problems: insufficient funding; insufficient state support for project financing; distrust of co-owners to the effectiveness of the project; unsatisfactory condition of the apartment building, which requires significant financial costs. The growth rate of the number of condominium applications shows an increase in public confidence in the Program. However, they are not enough to talk about launching large-scale energy modernization of multi-apartment housing. Financial support of local authorities to their residents in the implementation of energy saving measures will contribute to even better results.
