Abstract. In accordance with the instructions of the customer, we examined one of the buildings in Moscow with the aim to give practical recommendations for the reconstruction, in particular, of building walls for their compliance with the new SNiP II­3­79* «Building heat engineering». The purpose of the survey is to determine the reasons for freezing the allocation of condensate on the inner surface of the walls of the building and, as a consequence, the loss of comfortable conditions in the building. You want to find the technical solution to implement it in the period of reconstruction. Visual inspection revealed the presence of main cracks on the surface of the building walls, up to filter the ambient air inside the premises. In the process, were studied the structure of the walls of the building, the materials of its components, performed thermal calculations, conclusions, and recommendations.

Key words: design, materials, insulation, vapor barrier, degree days, thermal conductivity, thermal resistance, heat transfer coefficient, vapor permeability, dew point, strength.
