Article represents recommendations on decrease in heat losses through heat-conducting inclusions of sandwich panels. Recommendations are based on the analysis of calculations by a finite element method in software package Elcut and thermal imaging. The purpose of this study is to increase the thermal protection of buildings built with sandwich panels for the South Siberia conditions. The way of decrease in the factor of cold bridges is studied by adding thermal insulation of panel node connections. The authors analyzed constructive joints: roof parapet, roof cornice and junction of wall panels.

Article represents recommendations on decrease in heat losses through heat-conducting inclusions of filler constructions of buildings. Recommendations are based on the analysis of calculations by a finite element method in software package Elcut. The purpose consists in the analysis of expediency of replacement of a steel reinforcement on glass composite reinforcement in design decisions of filler constructions in view of calculation of thermal fields. The way of decrease in the factor of cold bridges is researched by replacement of a steel reinforcement by glass composite reinforcement. It is analysed constructive units: fastenings of facing verst to a diaphragm of rigidity; adjunctions of an external wall to a column. On a result efficiency of replacement of a steel reinforcement on glass composite reinforcement in filler constructions of walls is revealed, and also results of calculation of thermal losses of design decisions of filler constructions of a building are resulted.

The aim of this work is to decrease the consumption of broken glass shortage for obtaining heat insulation materials on its base. The results of research of composition and properties of foam glass crystal materials from compounds of broken glass and high calcium slag obtained in burning of brown coal in Kansk-Achinsk field are shown.It is stated that compounds from mixture of broken glass and high calcium slag in quantity of 30-40% granulated with 30% of liquid glass of density 1400 kg/m 3 after burning pending 3 hours with endurance 20 minutes at 800°C provide the production of granulated and modular foam crystal materials. Bulk density of granulated materials is 180-200 kg/m 3 , compressive strength in cylinder is 1,0-1,1 MPa. Average density of modular materials is 320-400 kg/m 3 , compressive strength is 4,1-5,3 MPa.

The article presents recommendations for assessing the heat and energy efficiency of a design solution for a building envelope based on the calculation of energy costs during typical periods of time. The recommendations are based on the analysis of defects in thermal protection of building envelopes during design and construction, by studying design documentation, thermal imaging, calculation and verification of building envelope components. Results of calculation of temperature in hazardous structural sites for the design winter conditions with the help of software that implements the finite element method are presented. In the present paper, the design solutions of the nodes of the walls of residential buildings are considered, where, during thermal imaging, thermal bridge are visible through the external walls. It is shown that the using of multilayer brick walls in the apartment houses in a sharply continental climate is irrational due to the rapid deterioration of the properties of the insulation layer. Also, the thermal protection of buildings is influenced by the design solution defects and violation of construction technology.
