One of the key indicators that characterize efficient energy use for heating purpose is the specific value per unit area and/or volume. This paper is devoted to the study of various methods application features used to determine energy need for heating, which there are a large number [1]. Determination of energy need for heating based on experimental data has a number of approximations and inaccuracies, so it is advisable to establish the annual energy need for buildings based on the calculated approaches. Addressing these challenges requires the use of calculation methods and mathematical models. Till the recent years, the methods for determining energy consumption and energy efficiency assessment in Ukraine took into account only annual energy consumption for heating and did not take into account the need for cooling and hot water supply [2, 3]. According to standard [2], the building energy efficiency should be determined on the basis of calculated or actual annual energy consumption for heating needs, while ensuring appropriate sanitary and hygienic norms in the building spaces.
