Title: Saving on heating by replacing windows
In many developed countries, including Russia, based on the long-term experience of Germany, projects for non-volatile or passive houses have been developed for a long time. The passive house has a high level of sealing and improved thermal insulation, which allows you to accumulate heat and solar energy indoors.The research results have confirmed that the passive house is perfect in terms of energy consumption efficiency, maintaining a constant temperature and maintaining a favorable microclimate. Unsurprisingly, its main advantage is cost-effectiveness. In residential buildings built on the basis of such technology, heating and air conditioning costs are surprisingly low compared to "ordinary" houses.In the conditions of a cold Russian winter, even at outdoor temperatures below -30 degrees and +20 indoors, heat loss for a passive type house is 50-65 kW per square meter per year, which is about 5 times lower than for standard brick structures. Due to the low energy efficiency of most buildings in our country, heat losses during heating reach enormous proportions. In a year, 400 to 600 kW of heat is wasted per square meter of area.Reducing heat loss is possible to minimize heat loss either directly at the construction stage of new buildings, or by carrying out energy-saving measures as part of the overhaul of existing ones. To do this, it is necessary to block all ways to access the cold, that is, eliminate areas (so-called bridges) in which intensive heat exchange with the environment is possible. The average air temperature, the area of the external surface, the number of windows and doors directly affect the amount of energy needed to preserve heat inside the building. According to the data obtained from the BTI passports, the window area is approximately 30-40% of the total wall area. Their thermal protection is much inferior to the thermal protection of the walls, therefore, in the cold period, windows account for more than 25% of all heat losses at home. The percentage increases if the frames have a large area, and the joints between them and the walls are poorly treated.About the bad and the good, wooden windows with sheet glazing, due to the gradual aging of the wood and the deterioration of the glass seal, have the highest infiltration ("seepage"). Plastic windows, due to their high tightness, retain heat more efficiently. Tightly closed, they do not penetrate even in strong winds. They do not need to be additionally isolated for the winter. The galvanized steel profile, which makes up the supporting frame, gives extreme strength and stability to the entire window structure.Unscrupulous sellers of plastic profiles are willing to use this and offer to replace old wooden frames with ordinary glass with PVC with single-chamber double-glazed windows. Therefore, in the minds of consumers, there is even a firm idea that wooden windows are necessarily bad, and aplastic windows are good. And this is despite the fact that in fact the effect of such a replacement is almost zero. Few people know, but plastic windows with single-chamber double-glazed windows do not comply with the norms existing in the climatic zone of the Volga region: they are generally not recommended to be installed.Energy-efficient window heat loss is always due to the glazed structure itself, and its amount is determined depending on the following three factors:- Thermal conductivity - the ability of glass to transfer heat from areas with a higher temperature to areas with a lower temperature;- Convection - movement of warm and cold layers of air; - Thermal radiation.This means that in order to reduce heat loss, it is necessary to use the most efficient window structures that have a high resistance to heat transfer.What parameters distinguish an energy-efficient window from a conventional one?- A profile with five or more cameras has a width of 70 mm. A system of closed internal cavities of different volumes is located opposite to the direction of the heat flow, which increases thermal insulation.- A special double- or three-chamber double-glazed window is installed.- The interstitial space is filled with a special inert gas with a lower thermal conductivity than air.- Special glass with a low-emission (selective) protective coating reflects thermal energy back into the room and reduces thermal radiation.- Instead of an aluminum remote frame, a plastic one is installed in the double-glazed window. This ensures optimal thermal insulation along the contour and prevents condensation.An energy-efficient window protects the heat generated by heating and household appliances in winter, and is able to keep cool in the hot season.The interstitial space is filled with an inert gas with a lower thermal conductivity than air (it should be borne in mind that Ar, the most commonly used inert gas, does not significantly affect the thermal characteristics of a double-glazed window). Special glass with a low-emission energy-saving coating (does not pass thermal energy) Instead of an aluminum spacer frame, a plastic one is used in a double-glazed window, which has a higher coefficient of resistance to heat transfer. This provides higher thermal insulation along the contour of the double-glazed window and prevents the formation of condensation on the surface of the inner glass.An energy-efficient window protects the heat generated by heating and household appliances in winter, and is able to keep cool in the hot season.In other words, it allows you to maintain the temperature inside the room at a certain level. Heat loss is reduced by 60-80%! Due to this, it is possible to significantly reduce monetary costs: in winter - for heating, in summer - for air conditioning.How much can you really save?Energy prices in Russia are constantly rising. As a result, utility bills are increasing accordingly. Not many people can afford to build a passive house. And a large-scale overhaul of buildings with all necessary measures for heat conservation is unlikely.If you replace conventional windows with energy-efficient ones, savings from each can amount to up to 4,000 rubles only in the first heating season. Their cost will be fully paid off in 3-4 years. Energy consumption will decrease 2-3 times. You will never have to use gas to heat rooms again.
