Development of cost-effective enclosing structures with high heat transfer resistance

Abstract

Considered is the solution to the problem of choosing an economical option for the construction of low-rise buildings and the creation of new economical design solutions with high thermal performance. The well-known technologies of building construction are analyzed using qualitative, quantitative and comparative analysis. Quantitative indicators were selected, such as wall thickness, weight of 1 m2 of wall, resistance to heat transfer, area of premises, cost, durability, tendency to shrinkage. As qualitative indicators used: seasonality of the use of solutions, resistance to the formation of mold, decay and destruction, especially the delivery of building materials. The method of multi-criteria analysis was also applied to determine the most effective technology. Calculated the cost of various types of design solutions based on economic calculated simulations. The technological solutions were assessed by quantitative criteria on a ten-point scale, where the minimum and maximum values were assigned points 1 and 10, respectively. Graphic modeling of the compared construction options was carried out and the corresponding diagrams were built. Added “weight” coefficient of criteria for the final decision on the choice of the optimal technology for the construction of buildings. The most effective constructive solution was selected based on the results of a comparative analysis, taking into account the “weight” coefficient.

Evaluation of the New Constructive-Technological Solution of the Fence Structure in the Non-Removable Formwork

“…Quickly constructed low-rise residential buildings (1-3 floors) can be divided into frame (with a metal or wooden frame), frame-panel, panel and modular. It is worth noting that the construction of such buildings, in addition to speed and cost savings, prioritizes the environmental friendliness of buildings and the health of their residents [2].…”

“…Based on the analysis of information sources [1][2][3][4][5][6][7][8][9][10] and calculations of heat transfer resistance [12,13], the thickness of enclosing structures, cost estimates of the cost of 1m 2 of erecting enclosing structures, a comparison table of structural and technological solutions according to the selected criteria was compiled. Quantitative evaluations of the criteria are given from real-time measuring devices into a single point scale.…”
