Now, it is noted in the explanatory note to the document for factual assessment of the efficiency of a home necessary statistical data of metering devices of thermal and electric energy for 3-4 heating seasons. “Every object is transformed into an experimental platform for research, the cost of which exceeds tens of millions of rubles each,” – say the developers of the rules. When you enter the building it is impossible to reliably predict the pattern of energy consumption and error of the conditional models are often greater than the error of the design calculations.
to Determine the energy efficiency class according to optimal design parameters of buildings, according to the Department. This will have to do a authorities decree or Gorgiladze. The new procedure will help reduce the cost of construction, and 20-30% lower operating costs.
Now two-thirds of the buildings have low energy efficiency classes, the expert of the thematic areas of the onf “Housing and the urban environment” Paul Sclancy. “Savings in the construction phase leads to higher exploitation, he said. For example, only 5% of houses have individual heating units with climate control. If not, then when the warm weather during the winter, people overpay for heating”. In the old housing stock, the energy consumption is twice higher than in modern buildings. To solve this problem you can either complete overhaul, or energy service activities. “But you need to develop loan products, and also include energy service in the system of calculating subsidies and benefits for utility services,” says Sclancy.
