| Summary: | Now, the thermal protection of buildings is determined by the assessment of the heat consumption for heating and ventilation of buildings during the cold period, which should not exceed the energy consumption norms chosen by a volitional means. At the same time, the economic indicators of the operation of engineering systems serving the building are not taken into account, and energy costs for maintaining the thermal microclimate in the warm season are not considered. The economic assessment of the thermal protection of a building should take into account the year-round operating costs of maintaining a thermal microclimate in it and the capital costs of the systems themselves and their connection to power supply networks. These costs are in antiphase with the capital costs of building insulation, which increase with the strengthening of thermal protection. Since building insulation is a very expensive part of construction, it is important to determine its economically feasible level, taking into account the cost of all the listed costs in the conditions of the climate of the construction area and territorial economic indicators.
