The article presents an overview of the current situation in the field of energy saving of the Russian Federation. Topical issues of energy efficiency control of buildings and structures as an energy saving tool are considered. The proposed approach allows, while maintaining the General ideology of SP 50.13330.2012 "Thermal protection of buildings", to modify the scale of energy efficiency of buildings and structures, to make it comparable with similar scales adopted in leading European countries. A similar approach to solving this problem is implemented in order to move from the percentage deviation of the level of heat loss (from some basic value) directly to the specific level of these heat losses per unit area. The formula allowing to calculate both normalized and actual value of heat energy consumption for heating and ventilation of buildings is deduced. In the future, the above-mentioned formula is transformed into a formula that takes into account engineering solutions, both with a direct-flow ventilation system and with the use of a recuperative heat exchanger.

In the paper, on the basis of the equation of motion of an incompressible lubricant having the micro-polar properties for the case of a ""thin layer"", the equation of continuity, Darcy and the formula for the energy dissipation rate for determining the function Ф (θ), caused by the molten surface of the bearing bush covered with a low-melting metallic melt of a carrier asymptotic solution by the thermal parameter K. Using a self-similar solution for the zeroth approximation, i.e. without taking into account the melt of the low-melting metallic melt, and for the first approximation, taking into account the low-melting metallic melt, the velocity and pressure fields in the lubricating and porous layers are determined, and the basic performance characteristics of the radial slide bearing are determined. The characteristic permeability of the porous layer and the melt of the surface of the bearing bush, coated with a low-melting metallic melt, on the load capacity and frictional force are estimated.
