Modern construction technologies are developing mainly through the use of new materials and minor changes in the design of buildings. At the same time, construction equipment has changed little over the past 30 years. In construction, 3D printing allows to increase the efficiency using new building materials, reducing labor costs, applying an almost waste-free construction method, and employing various new geometric solutions of structures that are difficult or impossible to use in traditional construction.
This paper presents three different designs of a building’s outer wall, some of which have already been used in practice. For calculated construction materials, the authors use popular heaters and concrete mixes that have been or can be used in the construction by this method.
The authors have performed a thermal calculation of the structures according to the developed methodology, taking into account the regulatory requirements for the enclosing structures of a residential building. The method of calculating the building envelope is based on the application of the Fourier law, the calculation is performed using the ANSYS software package. For each design variant, several combinations of building materials were calculated.
The dependence of the heat flux on the outdoor temperature is obtained. The most and least heat-efficient design options are determined. An economic calculation was carried out to determine the cost indicators of construction and the cost of operating the developed structures both among themselves and in comparison with the traditional structure. The most cost-effective design of the exterior wall of a residential building has been determined.
