The linear coefficients of heat transfer of the units of the adjacent balcony slab to the outer walls, which is recommended by the existing regulatory base, are analyzed. It has been found that the existing design of the junction site is not sufficiently energy efficient. To increase the thermal resistance of the node adjacent balcony plate proposed an improved method of its structural implementation, which is protected by a patent for utility model. Reduction of heat losses is achieved by arranging a layer of foam insulation in the place where the wall adjoins the balcony slab. The energy efficiency analysis of the proposed structural implementation of the junction of the adjacent balcony slab, as a "bridge of cold" was performed according to the results of mathematical modeling in the software program An Therm. According to the simulation results, the temperature distribution at the junction point of the balcony slab is determined. The linear coefficient of heat transfer of the recommended node of the adjacent balcony slab is determined, the value of which is greater than in the existing structures. The results obtained confirm the feasibility of the implementation of the proposed structural implementation of the junction of the adjacent balcony slab, in order to improve the energy efficiency of the thermal insulation shell of the building.
