“…But despite the obvious relevance of use of this material is limited. This is due to the fact that the thermal engineering calculation is widely studied [2][3][4][5][6][7][8][9][10][11], which allows us to use sandwich panels as walling. However issues of technological and regulatory plan and strength calculation remain open and require active discussion [12].…”

Abstract. This paper considers the issue of sandwich panels using as load-bearing structural elements. The comparison of deflections and critical failure loads were obtained by the results of the full-scale roof sandwich panels tests conducted by the company "Joris Ide" and the theoretical design, according to the calculation method described in Euronorms. Based on these results it was concluded that sandwich panels can be treated as a load-bearing structure only with more taught manufacturing requirements. Thus, the reduced spread of critical loads can be achieved.

Abstract. Thermal stability of the enclosure structures is one of the most important objective in the building design. Thermal processes in the wall depend not only on the internal and external air temperature, but also on many other factors. Therefore, complexity of this process make heat conservation in the room to be an actual problem. This paper presents dependence between thermal stability of the enclosure structure and its design. It was shown that thermophysical characteristics of materials directly affect the thermal processes in the wall. For the research, three frequently used types of enclosure structure in Russia were taken. For each wall was found the average temperature and cooling time. As a result, it was found that the higher values of thermal conductivity, specific heat and material density are, the higher average temperature of the wall is.

“…In addition to improving the appearance of buildings, raise thermal insulation of the building envelope leads to decrease of transmission heat losses [1][2][3][4][5][6]. The lower the heat loss in the building, the lower the amount of thermal energy is required to bring to the building from a heat supply source to compensate for transmission losses.…”

“…The lower the heat loss in the building, the lower the amount of thermal energy is required to bring to the building from a heat supply source to compensate for transmission losses. Thus, the thermal insulation leads to decrease energy consumption in the building and consequently to reduction of payments for heating [3][4][5][6].…”

Abstract. At the end of the 90s, with the introduction of changes in the regulatory documents of the Russian Federation №3 to SNiP II-3-79*, regulatory requirements for thermal protection of buildings were revised towards increase. For this reason, the buildings built till 2000 don't conform to modern requirements. The actual solution of this problem is to carry out works on renovation of facades of the existing buildings with the use of innovative materials. As object of research one of educational cases of Peter the Great St. Petersburg Polytechnic University has been chosen, where by practical consideration the size of the actual thermal resistance of external walls has been determined by heat flux meter, the numerical value of which was significantly lower than the standard values. Based on the obtained data two modern ways of thermal insulation of facades (Ventilated Façade System (VFS) and External Thermal Insulation Composite System (ETICS)) have been analyzed, the assessment of energy saving potential and the discounted payback period of the investments directed to warming of facades has been made.
