Concern for the environment, as well as concern about energy efficiency - undertaking inherently good. But you can not throw out the scheme of man: his interests, too, should consider taking care of nature. Not always "green" house is convenient for its inhabitants. Have energy-efficient housing and another significant drawback: it is considerably more expensive than "normal."
Energy-efficient housing program aims to improve the global environment (in this case under the "ecology" refers to causing less harm to nature). However, it is thought that the man himself is a living and integral part of nature, and his health is worth considering, too, in great detail.
There are programs in the "home" energy efficiency and global discomfort, which says Alexander Zimin. "For example, a typical low-energy house is worth about 25% more expensive. Therefore, even a staunch supporter of saving nature will not buy a house if the price for it is a priority factor. And in Russia, an acute shortage of skilled personnel in the field of green building, not enough knowledge about the latest developments and suppliers ekoproduktsii, the perception of the construction costs of green buildings as unreasonably high and outdated regulations and codes. "
And anyway, do we have in Russia, examples of green building is housing?
In our country, the so-called "green" building development is much worse than in Europe, the U.S. or Canada. If in these countries is actively developing a green building for two decades, in Russia only in 2009-2010, the federal government began to show interest in the implementation of energy efficient technologies.
Isolated examples of green building in our country is, however nearly all of them from the sphere of commercial real estate. If the environmental office or shopping center, one can count at least a couple dozen, then in the residential sector, such buildings can be counted on the fingers of one hand.
Current examples - a gated development Townvillas Green Apple, residential complexes Swedish krona in St. Petersburg and "Hussar Ballad" in the Odintsovo district, district in Yekaterinburg Academic and residential buildings in Moscow on the streets of the Soviet Army and Nikulin.
Townvillas Green Apple is in the Odintsovo district, near the village of Zhukovka. High level of energy efficiency in the settlement reached by alternative engineering equipment: geothermal pumps and solar panels.
Pumps at work uses earth energy, solar panels installed on roofs with light sides of the world with the possibility of installing additional panels. High level of energy provide construction materials with improved properties of thermal insulation, green roof.
Residential Complex "Swedish Krona" is built in St. Petersburg, in the Primorsky district, near the metro station "Specific". Application of energy-saving materials allows for a quarter to reduce power consumption.
In the Moscow area Nikulino built an experimental 16-storey building. Hot water system of the building does not depend on the central heating: her work is based on the use of low-grade heat the soil. In a system of mechanical ventilation exhaust air heat is applied. As a result, achieve an expenditure of heat energy for a third less than the usual types of home.
What are the myths and misconceptions exist on energy-efficient housing?
Some active environmentalists believe that the development of energy-efficient housing construction slowed down only because of bureaucratic red tape. In their view, if the government would encourage the production of energy-efficient building materials and provided incentives and subsidies to companies introducing energy efficient technologies, in terms of green building, we would have reached the level of developed countries.
Of course, it is possible in accordance with the concept of ecological technocracy stimulate the production of synthetic substitutes for many natural resources. However, to increase the number of sunny days per year or thermal ground water sources can be neither economic nor administrative methods.
Then, one can not only administrative measures to change people's attitudes towards the environment, and in fact this aspect is often the determining factor in choosing an apartment in the green house. In addition, as we have said, the use of the vast majority of energy-saving technologies do not reduce but increases the final cost of the project - about a quarter. This fact can discourage from buying even convinced the "green" if it has no surplus funds.
What advice would you give to someone who is not indifferent to the topic of energy efficiency, an important environmental protection, but does not have to buy a new, environmentally-calibrated home enough money?
First, the already mentioned energy saving light bulbs: it is hoped that by the time the light bulb will burn out - and they work for a long time - the issue with their convenient disposal has to be solved. The obvious benefit here also to save on electricity costs (about 300 rubles. A year with one headlight, but still).
If you switch to energy efficient lamps for some reason does not work, you can use the power regulators, which varies with resource use (say, a 100-watt bulb can be used by only 10% of its capacity). Do not forget to purchase energy-efficient appliances (A, A + and A + +) - yes, it is more expensive than usual. Still, this is not the scale that by buying "green" housing: While this option is available rather a very well-endowed people with fads than environmentally indifferent to ordinary citizens.
