The use of new technologies in the construction and operation of prefabricated buildings with ultra-low energy consumption

This article provides a brief overview of new technologies developed for use in construction in cold regions of China. These technologies aim to significantly reduce environmental impacts, lower winter heating costs, and create comfortable living spaces during high summer temperatures. Chinese scientists have created ultra-low-energy buildings that are not connected to the central heating system. The following technical solutions are proposed for highly efficient heat conservation in residential spaces during the winter: a prefabricated building structure integrated with a solar heating system; the use of heat accumulators; and the development of a geothermal tunnel ventilation and heating system. To reduce indoor temperatures in the summer, the installation of sun protection systems, as well as thermally insulated roller blinds on doors, windows, and external walls, is proposed. These technological advances have been shown to significantly reduce building operating costs and carbon emissions. The implementation of this integrated technology in the construction of residential buildings in cold climates will enable the commissioning of heating systems without the need for public heating and will reduce carbon emissions over the entire life cycle.
