Abstract: This article is devoted to the analysis of multilayer enclosing structures used for the construction of exterior walls of low-rise buildings based on a comparison of thermal and economic indicators. For the calculations in this article, the most relevant and popular multilayer wall designs are selected. The object of the study is the structural solutions of multilayer wall enclosing structures in low-rise housing construction, which are used in the city of Krasnoyarsk. The subject of the study is: the influence of the composition of multilayer wall enclosing structures with a similar heat flow on the estimated cost of their construction for the city of Krasnoyarsk and the estimated cost of 1 square meter of each wall structure is determined. At the moment, the construction of low-rise residential buildings is gaining popularity and is supported by state programs both at the federal level and at the levels of the subjects of the Russian Federation and municipalities. Low-rise housing construction is considered as one of the possibilities of solving the housing problem or improving housing conditions for the population. Multilayer enclosing structures with exterior facade decoration have been widely used in low-rise and multi-storey construction. As part of the study, we considered the most common types of multilayer structures and exterior wall facade finishing options, performed thermal engineering and cost estimates to determine the most profitable option for a multilayer wall structure in low-rise housing construction.

Abstract: This article delivers the calculation of moisture accumulation of the wall structure in the annual cycle for the climatic conditions of Krasnoyarsk. Analysis is conducted on the multilayer wall structure made of cellular concrete, with the plaster based on cement-sand mortar as top layer and use of thermal insulation in the form of mineral wool board. The subject of this research is the typical corner unit made of cellular concrete in combination with monolithic belt and an inter-floor overlap used in low-rise construction. The author acquires the results of moisture accumulation in layers of the structure for each month within one year, depending on the climatic parameters. The novelty lies in the fact that the outdoor climate and sorption moisture influences the accumulation of moisture in construction materials, creating a large seasonal increase in moisture. Consideration of these factors in the design process, allows making the structures more durable and energy-efficient. The conclusion is made that the distribution of moisture structural layers under climatic conditions. Krasnoyarsk is uneven throughout the year; however, meet the regulations. It is recommended to conducted regulation in the design in order to maintain the level of moisture in construction materials
