Zero Energy Buildings and Features of Their Arrangement

Zero energy buildings belong to the class of low energy consumption buildings, and in them the cost of thermal energy for heating and ventilation systems is reduced to a minimum (almost zero) compared to buildings under construction today. The primary energy expenditure for heating and ventilation, electric and hot water supply of these buildings does not exceed 120 kWh/m2 per year. The said energy is produced on site at the expense of renewable energy, which eliminates the need for fossil heating, including natural gas, in these buildings. The amount of CO2 emitted from these buildings into the environment is zero. Such buildings significantly reduce energy consumption in heating and ventilation systems, that is, they reduce harmful emissions to the environment, which are caused by the burning of fossil fuels in the corresponding heat generators. Zero energy buildings, or zero buildings, as they are often called, are widely implemented in many countries of the world, and their implementation in Georgia is an important issue for the development of the country, which is provided by the law of Georgia on energy efficiency. The use of the materials presented in the article will contribute to the saving of heating and energy resources in the country in such an energy-intensive direction as construction.
