To function effectively, at home, regardless of what building materials it is built, it needs energy for heating, water heating, ventilating and air conditioning, lighting and all sorts of household equipment. We use energy in the form of heat and fluids: gas, liquid fuels and electricity. Energy costs are a major cost factor associated with the use of the house, besides the price of energy continues to grow steadily, with this increase and the cost of maintaining a home. These costs can be significantly reduced in the case if the house is built in compliance with energy-saving standards. Energy saving house – it's heating facility which is several times cheaper than the traditional home. Energy-saving standards for equipment are modern and efficient home heating, cooling, ventilation, equipment home energy-saving lamps.

Energy-efficient home construction is carried out energy-efficient building materials with simultaneous traditional, such as concrete, brick, wood, stone, glass … Besides the construction of energy-efficient homes use the most efficient thermal insulation materials, better insulated walls, roof and floor (building envelope at home). External walling at home, such as floors, ceilings, roof necessary to prevent leakage of heat. In energy saving house, average heat transfer coefficient is not exceed 0, 2 percent. In order to achieve such qualitative indicators need to use thick layers of insulation for all the above enclosures, whose thickness should be It is at least 20 cm through walling house will take the greatest amount of heat, such as through a window lost about 15-25% of the heat, the roof – 10 – 25%, half 3 – 6%, the ventilation system 30-406% Wall 20 -30%. High-quality thermal insulation walling at home, we do not achieve satisfactory effect. So how, in a poorly insulated house a considerable part of the heat goes through the cold bridges are formed such as expansion joints in load-bearing slabs walls of the house, as well as in contact the internal walls and partitions, with external walls, joints walling, as well as subsidence does not possess the necessary quality of thermal insulating material in sandwich Walling home with a heat insulation material as a middle layer.
