How to build an energy efficient home
Heat losses in buildings vary depending on the number of storeys, the type of building envelope, the quality of construction work, and so on. For example, the heat losses of a typical nine-story house are as follows: 45% of the heat is removed through the building envelopes (that is, performing the functions of enclosing or dividing the rooms inside the building); through the windows - 35%; through the roof, attic and basement floors - an average of 10-15%. Therefore, in construction, systems of energy-efficient technologies are actively used, aimed at the rational use and replenishment of energy consumed.After the global oil crisis of 1974, the world community first thought about building energy-efficient buildings, which are a combination of architectural and engineering solutions that minimize energy consumption while providing indoor microclimate. “In Russia, the government began to think about energy saving technologies in 1996 after the adoption of federal law No. 28-F3“ On energy conservation ”. Later, a new SNiP 23-02-2003 “Thermal protection of buildings” was introduced. The energy efficiency classes of buildings were also formulated, and the requirements for heat transfer of building envelopes were tightened, ”said Ksenia Pashkevich.
