This study aims at considering the methods of calculating heat losses to the soil through the floor structures of the basement. Classical methods of calculating heat losses through the soil according to the updated set of rules are presented. Modern methods of calculation based on mathematical modeling have been studied. A full-scale experiment of one of the developed methods that proves the possibility of its application and the need for further enhancement has been considered. Methods for estimating the resistance to the heat transfer through the soil are introduced. The method of “concentric circles” is presented in comparison with the given values in Set of Rules 50.13330.2012. A comparative analysis of new methods with standard methods for calculating heat losses to the soil through the basement floor structures was carried out. Such methods as calculation “by zones” based on the principle of dividing the basement floor into strips have been studied. Various options for the building basement insulation that can affect the heat losses of the building have been considered. An analysis of the factors influencing heat loss such as the type of soil, the geometric dimensions of the building, the actual heat transfer resistance of the insulation, the temperature regime of the room and the presence of insulation has been presented. The formulas for calculating the complex heat-shielding characteristic in accordance with modern changes in the regulatory documentation are given.
