Efficiency of the methods of insulation of basements

Abstract

Due to the low energy efficiency of buildings, heat loss buildings make up 47%, 12% of heat is lost due to worn-out networks, and 5% due to outdated boiler installations. With the help of heat modernization and overhaul in homes, you can reduce annual consumption and energy losses by 10-25%.

At the same time, in Ukraine as a whole, the potential for reducing energy consumption is 75%.

The main consumption of energy in the residential sector is connected with the heating of the house due to heat losses through windows, walls, roof, floor and due to ventilation. To save on resource costs and reduce heat losses, energy savings should be attributed to consumers, in systems of heat supply, heating, ventilation and air conditioning. The solution to these measures is related to the thermo-modernization of buildings through insulation of exterior walls, attics, roofs, etc., as well as replacement for more energy efficient windows and doors; increase of useful energy use due to the use of recuperators, thermoregulators, heat pumps and other new energy-saving technologies. The introduction of measures for thermo-modernization will help to increase the service life of the residential sector buildings.

Previous studies have shown that even during the thermo-modernization of buildings, the issue of insulation of the walls of basement or basement premises often neglects or reduce the required thickness of the heater.

The classic layout of the wall insulation of the basement involves a significant amount of excavation work related to soil extraction, backfill, and reclamation. Performing such works to the required depth is not always technically feasible and is always materially costly. The same operations during the construction of a new building are introduced into the general cycle and increase the duration only for the immediate implementation of the insulation of the insulation, waterproofing and mechanical protection of the heater.

To cheapen the work, and sometimes the only technically feasible option is the insulation of the wall is not at full depth with the insert of the heater under paving. Let's check also the variant which unites the two previous ones.
