AbstractThe article presents the results of the analysis of the effect of the parameters of the external wall of a building, constructed using 3D technology on its heat engineering propertis. The dependence of the heat penetration coefficient Λ (function Y) of the wall on the followig factors has been constructed: the thickness of the outer walls d1 (factor X1), the thickness of telongitudinal partitions between the voids d2(factor Х2), the number of voids in the wall cross section in the transverse direction m (factor X3), the number of voids in the wall section per 1 rm in the longitudinal direction n (factor X4), the thermal conductivity coefficient of the heat-insulating material in the voids A1 (factor X5), provided that the cross-sectional area of the bearing part of the wall, taken under the condition of ensuring strength. The data set foranalysis was obtained by implementing a computational experiment. The analysis and optimization of the parameters was performed on the basis of a deterministic mathematical model that describes the presented dependence for the selected void formation scheme in the wall. The information may be useful for scientists, designers and technologists involved in the development of structural solutions of buildings using 3D printing technology.
