Using the index approach to select wall materials for low-rise construction

The article proposes a mechanism for determining the cost effective alternative for wall structures using the price index to the unit of heat conductivity of the material. This method makes it possible to find the optimum ratio of the required heat conductivity to the cost per square meter of the wall. For this purpose, the variants of wall constructions for low-rise building offered by organizations of the Yekaterinburg city were analyzed. The statistical data of the wall fencing materials using was given, and their main advantages were listed. The software heat engineering calculations for different variants of the wall fencing of the low-rise construction were carried out. During the calculation, the parameter of the heat transfer resistance was determined. To find the ratio of the price index per unit of heat transfer resistance, the cost per square meter of material was calculated and based on that the most cost effective alternative for low-rise construction in the Sverdlovsk region was selected.
