The article discusses the energy-saving technology "passive house". The advantages and possibilities of using materials in the construction using this technology are described in detail. The problems of technology implementation in Russia are explained, the tasks of the institute, which was opened for the improvement of the "passive house", are revealed. A huge number of new facilities, both residential and industrial, are being built in Russia every year. Construction companies try to improve their activities as much as possible, introduce new technologies, and try to make their object as economical as possible when designing. One of the main requirements in the construction of buildings is energy efficiency. Due to the fact that all facilities will be operated for decades in conditions of a shortage of energy carriers and an increase in their cost, the issue of energy conservation is a priority. According to the data shown on the graph, the cost of 1 Gccal of thermal energy in the CBD has increased by 35-40% over the past five years.[3] Statistics of recent years show that the climate is rapidly deteriorating, oil and gas prices are rising, in this regard, it is necessary to take into account possible energy savings during the construction of facilities. Experts want to minimize the use of natural resources and, in their opinion, the construction industry is one of the main ones. The "passive house" technology has become one of the main innovations that helps to save energy. The essence of this technology lies in the fact that when designing the construction of an object, the calculation of indicators that do not require a special heating system is carried out. At the same time, energy consumption in new buildings is reduced tenfold. To obtain these indicators, even during construction, increased thermal insulation is created. At the same time, the criteria for heat leakage, the use of solar energy, and the tightness of the building must be taken into account. note that high-quality windows with high thermal conductivity should be installed, as well as installations for saving electricity.
