An increase in population, an increase in electricity consumption, and a decrease in the reserves of the Earth's energy resources make us think about creating more energy-efficient construction methods designed to reduce the amount of resources consumed. There is a need to develop concepts aimed at rational energy consumption, as well as the transition to renewable energy sources.
One of the possible solutions to reduce the energy consumption of cities, widely used in Germany, Norway, Denmark, and other European countries, is the construction of energy-passive houses.
The term "energy-passive house" (passive house) is commonly understood as a building (structure), the main feature of which is ultra-low energy consumption, incl. heating and ventilation systems. An indicator of the energy efficiency of the facility is the loss of thermal energy per square meter (kWh/m2 per year or during the heating season). For an energy-passive house, this figure should be less than 15 kWh / (m2 year).
The design of energy-efficient buildings is a hot topic. The transition to this type of building can significantly reduce the consumption of fuel and energy resources, and reduce the cost of energy supply.
