The Choice of Economically Feasible Thermal Protection of Buildings in the North of the Russian Federation

It is shown that it is not enough to choose the level of thermal protection of enclosing structures only by energy indicators. For this, economic factors should be taken into account. To select an economically justified level of thermal protection, it is necessary to consider the energy costs for maintaining a year-round thermal microclimate in buildings, and not just during the heating season. In this case, it is necessary to take into account not only the cost of insulation and energy that replenishes the heat loss of the room, but all the financial components of capital and operating costs, which are affected by the thermal protection of the building. Appropriate level of thermal protection depends on the climatic characteristics of the construction area, taken into account in the form of degree-days of the heating period. But this is not enough, since the need for energy to maintain the thermal microclimate in the premises is influenced by the climatic characteristics of the warm period of the year. As it turned out, the appropriate level of thermal protection is also affected by the configuration of the building, which, in conjunction with thermal protection, is taken into account in the work using its specific thermal protection characteristic. Since there are areas in the Russian Federation with a different ratio of the duration of the heating and cooling periods and the configuration of buildings is individual in each case, the level of thermal protection of each building should be selected based on the basis of calculation.
