The main features and goals of energy efficiency in residential construction are considered in order to ensure minimal heat loss of buildings, and thus reduce the use of the required amount of energy to compensate for heat losses. With the increasing energy crisis and the deterioration of the environmental situation in large cities, recently foreign countries have attached importance to the rational use of energy resources. Facades are one of the main elements that provide a solution to improve the energy efficiency of the building itself, as they reduce the heat loss coefficient to a significant level. Today, Germany is a world leader in energy efficiency, as the country uses the most modern energy saving technologies. The technology of using energy-efficient facades in Europe is already considered normal and at the moment the technology of using a ventilated facade, translucent facade system, "green facade", dynamic facade represent more progressive solutions to improve energy efficiency.
