The accounting analysis of the energy efficiency class of buildings in the calculations of the heating system in the design

In this paper, the authors analyzed the methods for calculating heating systems for residential buildings in terms of taking into account the largest number of indicators of the energy efficiency class. Based on this study, it was revealed that the most accurate method is the calculation of heating systems, taking into account factors. This calculation allows you to determine the possible increase in the energy efficiency of the building in thermal equivalent, which makes this work relevant and carries the scientific novelty of the study.
