How to build an energy efficient home

Energy consrevation is one of the main global problems and trends of the 21st century. Today, humanity has two opportunities for energy conservation: to minimize the consumption of non-renewable energy sources or to use energy resources as efficiently as possible. So, for example, to optimize energy consumption in buildings and structures today, energy-saving materials and structures are widely used.

Ksenia Pashkevich, the leading architect of the Metropolis company, told the publication Energy to People (No. 8/93, 2019) about the ways in which it is possible to reduce the energy consumption of buildings.

At present, the issue of energy saving is the most relevant in the construction sector. This is due to both environmental and economic aspects.Environmental degradation due to excessive emissions of various gases, limited reserves of natural resources, oil crises and higher tariffs for heat and electric energy are just a few reasons for the development of energy-efficient technologies, explains Ksenia Pashkevich, lead architect of Metropolis.The construction sector is one of the main energy consumers. Heating, ventilation and air conditioning of buildings takes two-thirds of the total energy consumed by buildings. In total, buildings use about 40% of global energy consumption.

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.
