Tasks in front of modern windows of Krivoy Rog
Krivoy Rog is located in the steppe zone with a hot dry summer. Plus, over the territory of the city formed the so-called "heat island", when the temperature is higher by 1.8 ° C than in the suburbs or even in the private sector of the Trampark. In this climate, sun protection is important for homes. And, when deciding to buy windows in Krivoy Rog, you can pay attention to this problem.
It is proved in construction thermophysics that curtains effectively protect against sunlight, but do not protect from getting into the room of solar heat. Limit the amount of heat can a special sunscreen (multifunctional) glass in the double-glazed window or outdoor sun protection systems, which are used for the eastern, southern and especially western orientation of the windows. Double-glazed windows with multifunctional sputtering reduce the arrival of light and heat in the winter. The windows are most effective in combination with external sun protection:
- marquises,
- exterior shutters,
- rafts.
Another important problem for residents of Krivoy Rog is polluted air. In 2010, Krivoy Rog was recognized as the dirtiest city in Ukraine, according to the rating of the magazine "Correspondent", which was based on the data of the State Statistics Service on the level of emissions of hazardous substances into the atmosphere by enterprises and transport. Modern window solutions provide better sealing, in comparison with the Soviet carpentry, but there is a question of fresh air entering the room. According to DBN B.2.6-31: 2016 "Thermal insulation of buildings", even in the most energy efficient residential building, 80% of the air volume in the room should be updated every hour. Therefore, it is still necessary to let in air from the street. Air quality sensors are available on the market that analyze air inside and outside the premises and can tell when to better ventilate housing.
Like many large industrial cities, Krivoy Rog suffers from dust and smog, which also settles on glass. Therefore it is necessary to wash windows more often. To solve this task, which is especially important for facade glazing, self-cleaning glass was developed. Mud, which settles on the surface, decomposes into soluble components under the action of the sun, and then rainwater flushes it.
The authorities of the city and the region emphasize the excessive consumption of resources, which leads to higher costs of production and increased environmental load, therefore one of the important priorities is energy saving. And the replacement of old translucent structures with energy-efficient ones is one of the steps to improve energy saving for houses.
Energy saving in the housing sector of the city
In Krivoy Rog most of the population lives in houses that are more than 30 years old. We are talking about building in such microdistricts as: Sunny, Industrial, Ingulets, etc. Quite a few houses of pre-revolutionary buildings are concentrated in the City and they are also inefficient in terms of thermal insulation. According to the City Council, the typical house of the 70s consumes about 200kWh/m2 of fuel and energy resources per year, the 80s - about 150kWh/m22 per year, and according to DBN B.2.6-31: 2016 with a change of No. 1, now new buildings should spend no more than 48 kWh/m2 per year. New and modernized buildings are 3-4 times more efficient than old buildings and the norms will be toughened.
Therefore, the potential of energy-efficient activities is high. Experts pay attention that the complex modernization of the house is the most effective, but because of the cost it is broken down into the stages: replacement of window blocks, warming of walls, roofs, basement. If possible, it is better not to be tied to the minimum requirements for energy-efficient materials and the minimum cost. The most inexpensive windows in Krivoy Rog may not have the necessary performance characteristics for the Dnipropetrovsk region: neither heat, nor sound insulation, nor longevity.
Programs for increasing the thermal insulation of houses
Since the complex modernization of the old house it is necessary to invest significant funds, the authorities have developed a number of programs to stimulate the population. They are built on the principle of compensation for part of the loan taken for the purchase of materials or services.
Individuals can take part in all-Ukrainian programs "Warm credits" and "IQ Energy" to compensate for a loan for purchase, for example, windows, and in the case of "IQ Energy" - and slopes, ebbs, window sills, installation materials. The IQ Energy program of the EBRD has the task of improving the energy efficiency of housing by at least 20%, so compensation can be obtained for all the components that have affected the efficiency index. If you consider the example of buying plastic windows, then you can compensate for the cost of external sun protection (marquise, external roller shutters), if it goes in the same account with the window structure. But curtains or mosquito nets only affect comfort, so they are not compensated.
For a condominium to return part of the loan can be with the help of "Warm credits" and take part in the competition of mini-projects on energy efficiency and energy saving. At the beginning of the year, representatives of the AJOAH or associations of co-owners submit the project for participation in the competition and the city council selects winners, which are financed from the regional budget. Mandatory condition: 20% of the cost of the project is paid by the residents themselves. The competition is part of a program to promote civic engagement in the development of the territories for 2012-2021.
Energy Efficient Windows
Energy-efficient window units - low-emissivity glass-plated (i-glass) loss of heat from the room. But one i-glass is not enough to satisfy the efficiency requirements.
The Dnepropetrovsk region refers to the first temperature zone, according to the DBN, and the coefficient of heat transfer resistance of the window should be at least 0.75m2·K/W. This figure exceeds the metal-plastic windows of Krivoy Rog with a mounting width of PVC profile of 70 mm and even larger for aluminum and wooden profiles and a double-glazed double-glazed window with a width of at least 40 mm with two energy-efficient coatings and filled with inert gas.
OKNA.ua draws attention to the fact that these are the minimum requirements for window constructions. It is recommended to change it to a design with a coefficient of 0.9-1.0 m2·K/W. Manufacture of products with such indicators is widespread and they are widely available on the market.
OKNA.ua for searching for window solutions
To search for a window company, you can use the catalog OKNA.ua, where the largest database is collected firms. The platform has been working since 1999.
Participating companies place contact information, a description of their capabilities and advantages. To facilitate the search, filters are provided, including: sorting of companies that work with the state program.
Another advantage for OKNA.ua users is the opportunity to get acquainted with different offers simultaneously from different companies. On average, prices for Krivoy Rog windows will be the same as in Ukraine, but firms can optimize their offers, for example, free-of-charge measurement and delivery. Also, special offers and promotions may apply.
