As an object of research, the direction of optimizing energy saving and increasing energy efficiency of multi-layer enclosing structures (in particular, external walls) of buildings (with insulation and ventilated facades) was adopted. The high relevance of the research is related to the achievement of rational use (to an optimal level) of material and energy resources (with the correct choice of properties and location of the insulation in the wall). The accepted research method is based on the application of thermal engineering calculation of the external fence and its temperature field, other elements of the building heating system with the establishment of dependencies between the values and comparing them with the standard performance indicators (using the Mathcad program). Specific results of the study include determining the temperature distribution in the thickness of the 5-layer outer wall with fixing the plane with zero temperature of the material, which shows the place of possible freezing in the structure.
