As a result of thermophysical modeling of the aerodynamics of air movement in the bulk bulk horizontal air-soil heat exchanger and the gap of the thermal curtain of the facade wall of the house, it was found that by heating the air with the heat of the soil, it is possible to organize natural air circulation and stop using devices that consume electrical energy. At the same time, the presence of an air-soil heat exchanger reduces the temperature difference in the wall and, accordingly, the loss of heat. Soil-air heat exchangers make it possible to heat the air by 2-8 degrees Celsius, depending on the ambient temperature and the state of the thermally disturbed soil mass. Studies have been conducted on the effect of a number of factors on the air temperature at the outlet of the soil heat exchanger, as well as the dependence of the air velocity in the soil heat exchanger on the height of the air gap. The most influential are the temperature and condition of the soil. A program has been developed for calculating solar radiation near the Earth's surface with a special program code in the Python language, which makes it possible to calculate the intensity and energy of solar radiation at an arbitrary time for an arbitrarily oriented receiving surface. A method for the thermophysical calculation of the facade wall thermal curtain system has been compiled. Experimental studies of heat exchange processes during the passage of atmospheric air through a heat exchanger soil - air under various operating conditions were carried out. Validation of the thermophysical modeling of ground heat exchangers with a ventilated interlayer of the facade wall using experimental data obtained at the established facility, established the validity of the developed methodology. A method has been developed for calculating the thermal resistance of enclosing structures by using the thermal curtain of facade walls and roofs under different climatic conditions and soil conditions, and recommendations have been made to substantiate the possibility of using this technique in designing typical building thermal protection systems based on soil heat exchangers using natural soil heat.
