【 摘 要 】

The study describes climate changeability on the territory of the Russian Federation and in particular gives climate parameters for the area of St. Petersburg. It raises issues of energy efficiency of buildings' enclosing structures. Some results of field surveys conducted at cast-in-place civil buildings are compared with their design values. The study also updates issues of thermotechnical defects and thermal bridges in the structure in question, as well as the degradation of comfort level indicators. It also offers new types of structures ensuring heat insulation characteristics of civil buildings are not lower than the specified values. Moreover, the study presents the calculation model to determine the temperature field in the floor slab - wall connection node, as well as providing steady-state heat conductivity equations. There are also recommendations developed on how to apply the new types of enclosing structures in modern conditions of construction.
