How to save on electricity in an apartment. Download Energy Saving Clock Live Wallpaper - Full Version for Android v.4.2 Download Energy Saving Clock Wallpaper v 1.2

Any modern PVC windows, provided that they are of high quality and correctly installed, help to keep the house warm. There are special energy-saving glasses that reflect about 80% of the heat in the form of infrared radiation, returning it to the apartment, while ordinary glasses release this 80% into the street. This effect is achieved by sputtering particles of silver and other metals on the glass.

It has other benefits as well. Due to the reflection of a large percentage of heat, the difference between the temperature of the glass unit and the temperature of the room is minimal, therefore there is no so-called artificial draft. Being next to such a window is just as comfortable as anywhere else in the room. Also, energy-saving glass reduces the likelihood of condensation on the glass unit. In addition, in the summer it will not be hot in the apartment, since the glass will reflect heat onto the street and will not let it into the house.

A single-chamber energy-saving insulating glass unit is warmer than a conventional two-chamber unit, while being lighter, which makes it possible to increase its service life. The cost of an energy-saving glass unit is about the same as that of a conventional one.

Energy Saving Wallpaper

Such wallpaper helps to maintain a comfortable indoor climate due to its heat reflecting ability.

So, according to one of the manufacturers, energy-saving wallpaper KlimaTec Pro can save up to 75% heating time, that is, if earlier it took half an hour to heat a room, then with energy-saving wallpaper it will take only 7.5 minutes.

For a roll of 15 square meters, you will have to pay from 3.5 to 7 thousand rubles. It should be borne in mind that a roll of energy-saving wallpaper is 1.5 - 3 times larger than a standard roll of wallpaper. The average cost of a roll of high-quality non-woven wallpaper is one thousand rubles. If you choose wallpaper from the middle price category, then you can paste over a room with ordinary or energy-saving wallpaper for about the same money.

Motion Sensor

Many of us forget to turn off the lights when we leave the room. According to the Mosenergosbyt website, motion sensors can save from 14% to 20% of consumed electricity. The infrared sensor reacts to movement: the light comes on when a person enters the room, and when it leaves, it turns off.

For example, a motion sensor with a viewing angle of 160 degrees and a maximum motion detection distance of 9 meters costs from 500 to 1000 rubles. With an average monthly energy consumption of 100 kW on a single-rate meter, motion sensors will save up to 100 rubles per month.

Aerator

This is a special tap attachment that saves up to 40% water. The principle of operation of the aerator is that it reduces the amount of water consumed by enriching it with air bubbles. The water pressure remains the same, but due to its mixing with air, less water flows out of the tap. The decrease in the amount of water coming from the tap is not felt, but when paying the bills, the benefits are hard to miss. The simplest aerators can be purchased for 100 rubles, for more advanced models you will have to pay from 500 to 1500 rubles.

Economical shower head

Works on the same principle as the aerator. Allows to save up to 40-50% of water. The cost of a shower head varies greatly depending on the manufacturer, material, set of modes and design. The simplest models cost an average of 1,500 rubles.

As utility rates rise, thoughts about saving heat, water and electricity come to mind more and more often. Today, there are many energy-saving solutions and technologies, but their use is always associated with certain costs. Therefore, the calculation should take into account not only the numerical size of the savings that a particular solution gives, but also the ratio of the resulting savings to the costs of implementing this solution. To facilitate the difficult choice of investment in future savings, we have prepared a rating of the most popular energy saving tools available to a city dweller.

The main purpose of our small study was to calculate the economic efficiency of energy- and resource-saving appliances and technologies for the home. It sounds complicated, but in practice it is quite affordable: we calculated how much savings you can get in terms of 1 ruble spent on a particular solution. We also calculated how quickly each of them pays off, i.e. after what time after the costs incurred it is possible to start calculating the "profits". Naturally, these calculations are only estimates, since we do not take into account inflation, annual indexation of utility rates and some other economic indicators. However, this can be neglected to compare different solutions with each other.
In our calculations, we used the average for Russia in 2012 tariffs for heat (1400 rubles / Gcal), electricity (2.8 rubles / kWh) and water (20 rubles / m3 cold, 100 rubles / m3 hot and 15 rubles / m3 water disposal). Calculations for water were made for a family of three, and for heat - for a standard living room of 20 m2.

Part 1. Saving energy

We have been accustomed to saving energy since childhood. But if earlier for this you had to deny yourself something, today you can use special energy-saving equipment.

Energy-saving lamps

Thanks to the federal campaign to replace conventional incandescent bulbs with energy-efficient ones, they can be called the most popular means of saving the family budget today. And besides - the most affordable. Therefore, let's start with light bulbs: we will calculate the effect of using three types of energy-saving lamps: fluorescent, LED and halogen. And as a starting point, we will take an ordinary 60 W incandescent lamp, costing 15 rubles. and with a service life of a thousand hours. In this case, we will assume that each light bulb in the apartment burns on average 3 hours a day.

Fluorescent Lamp

Their service life is on average 8 thousand hours (with a daily three-hour operation, this is equal to 7.3 years), i.e. incandescent lamps for the same time we need 8 pcs. To provide the same illumination as a 60-watt incandescent lamp, an 11 W fluorescent lamp is needed, the average cost of which is 150 rubles.

	Incandescent lamp	Fluorescent Lamp
Billing period
	8 * 15 rub. = 120 rubles.
	60 W * 8000 h = 480 kWh 480 kWh * 2.8 rubles / kWh = 1344 rubles.	11 W * 8000 h = 88 kWh 88 kWh * 2.8 rubles / kWh = 264.4 rubles.
Savings for the billing period		(120 rubles + 1344 rubles) - (150 rubles + 264.4 rubles) = 1049.6 rubles.
Average savings per year		RUB 1049.6 / 7.3 years = 143.8 rubles / year
Approximate payback period
		1049.6 / 150 = 7 rubles.

LED lamp

The resource is on average 25 thousand hours (22.8 years), the equivalent power is 6 W, the average cost is 650 rubles.

	Incandescent lamp	Fluorescent Lamp
Billing period	25000 hours
The cost of lamps for the billing period	25 * 15 rub. = RUB 375
Energy consumption and electricity costs for the billing period	60 W * 25000 h = 1500 kWh 1500 kWh * 2.8 rubles / kWh = 4200 rubles.	6 W * 25000 h = 150 kWh 150 kWh * 2.8 rubles / kWh = 420 rubles
Savings for the billing period		(RUB 375 + RUB 4200) - (RUB 650 + RUB 420) = RUB 3505
Average savings per year		RUB 3505 / 22.8 years = 153.7 rubles / year
Approximate payback period		more than 3.5 years
Net savings for each ruble invested over the entire service life		3505/650 = 5.4 rubles.

So, despite the phenomenal lifespan and amazing energy efficiency, due to their high cost, LED lamps are still significantly inferior to fluorescent ones in terms of economic efficiency.

Halogen lamp
The resource is about 2 thousand hours (1.8 years), the equivalent power is 42 W, the average cost is 70 rubles.

	Incandescent lamp	Fluorescent Lamp
Settlement period
The cost of lamps for the billing period	2 * 15 rub. = RUB 30
Energy consumption and electricity costs for the billing period	60 W * 2000 h = 120 kWh 120 kWh * 2.8 rubles / kWh = 336 rubles.	42 W * 2000 h = 84 kWh 84 kWh * 2.8 rubles / kWh = 235.2 rubles.
Savings for the billing period		(30 rubles + 336 rubles) - (70 rubles + 235.2 rubles) = 60.8 rubles.
Average savings per year		RUB 60.8 / 1.8 years = 33.8 rubles / year
Approximate payback period
Net savings for each ruble invested over the entire service life		60.8 / 70 = 0.87 rubles.

Of the entire triad of alternative lamps, halogen is the least effective. However, the use of halogen lamps will be most justified in rooms where the light is constantly switched on and off (bathroom, toilet, etc.). Although they do not provide such high savings as fluorescent ones, they work in this mode much longer: with frequent switching on and off, the fluorescent electronics quickly fail, which makes their use in this mode meaningless.

Solar mini power plant

Today, solar panels can increasingly be found not only on the "wings" of space stations or on experimental sites of scientific laboratories, but also on the roofs of ordinary residential buildings. An apartment mini-power plant, consisting of a pair of relatively small (1.5x0.8 m) panels of a compact 5-kilogram inverter (DC-to-AC converter) and 4 batteries, similar to automobile ones, may well be deployed on the roof of a low-rise building or even on an ordinary balcony. And its performance (about 2 kWh per day) is enough, for example, to power all lighting devices in an apartment, a TV and a refrigerator.

Of course, a solar power plant, strictly speaking, cannot be regarded as an energy-saving solution, since it does not save electricity, but simply is an alternative source of it. But its use will undoubtedly reduce the amount of electricity bills. Let's calculate how profitable it can be.

Lifetime of the solar array	About 25 years (subject to replacement of batteries, the service life of which is about 10 years)
Estimated retail cost of a budget set of equipment and replaceable batteries for the entire service life	RUB 120,000 + 2 battery changers * 4 pcs. * 8000 rub. = 184,000 rubles.
Power output for the entire period of operation (assuming that the station operates all year round)	2 kWh * 365 days * 25 years = 18 250 kWh
The cost of generated electricity	18 250 kWh * 2.8 rubles / kWh = 51 100 rubles.
Payback of the station over the operating life	(51 100 rubles / 184 000 rubles) * 100% = 28%

So, in standard urban conditions, an apartment solar power plant will not pay for itself even by a third. However, as we noted above, it has a different purpose. So, in some settlements where there are frequent power outages, such a solution will be simply irreplaceable! It will also help in the case when the capacity allocated for the apartment is small and does not cover the needs of a modern family in electricity.

Part 2. Saving heat

Heat is the most expensive communal resource in a modern city. At the same time, a classic problem for the majority of Russian consumers is the lack of the ability to regulate their heat consumption, i.e. reduce it during periods of warming, at night, when there is no one at home and just when it feels hot in the apartment. As a result, we have to pay for the excess heat by heating the street through the open vents.

To really save heat, feeling the result of such savings with your wallet, you need to modernize the heating system (at least in old buildings) and switch to apartment metering. However, the latter is only a matter of time, since at the moment, the phased transfer of consumers to apartment heat metering in Russia is approved by law. And in order to start saving at the same time within the framework of a single apartment, you will need special devices:

Automatic radiator thermostats

They control the room temperature in accordance with the selected setting and, if necessary, automatically turn off or on heating devices (radiators). They often write and talk about thermostats today, but what kind of savings can they actually give?

According to the Danfoss company, which has been operating on the Russian market of automation for building heating systems since 1993 and has designed heating units for tens of thousands of residential buildings in different cities of our country, a complex of an automated heating point with weather-dependent regulation, automatic balancing valves on the heating system risers and radiator thermostats on heating devices with apartment heat metering gives an average savings of 35-45%, including 10-15% due to the use of the actual thermostats. However, this is far from the limit.

“In 2009-2011. We, together with the Moscow Government and the leading Russian design institute MNIITEP, conducted field tests of a set of energy-saving equipment, developed and adapted specifically for use in standard series of Russian apartment buildings with a single-pipe heating system1, - says Alexander Dubnyakov, head of the department "Automation of internal engineering systems" Danfoss, the world's leading manufacturer of energy-efficient heating equipment. - The tests were carried out on the basis of a 12-storey residential building No. 59 on Obrucheva Street in Moscow. Measurements were made both for the house as a whole and for each apartment separately. The results showed that with apartment heat metering, thrifty tenants can reduce their monthly heating bills by 65-70%! At the same time, the average savings in households as a whole amounted to about 45%, i.e. the use of thermostats gave in addition another 20-25%. However, as we remember, 10-15% of the 45% average household savings also come from thermostats. This means that in total they provided the residents with a house on the street. Obrucheva 30-40% savings in consumed heat ".

For the sake of fairness, it should be noted that similar results were obtained in other Russian cities, and in the most ordinary houses, where no one was specifically involved in testing equipment and did not conduct any control measurements. For example, residents of the "house with a spire", famous for the whole of Omsk and beyond, at the intersection of Maslennikov Street and Karl Marx Avenue, after the installation of the Danfoss thermal automation complex, began to pay 75% less for heat.

Let's calculate how much this savings will pour out for our room with an area of ​​20 m 2.

Service life of radiator thermostatsDanfoss
The cost of the thermostat and its installation	38-48 euros or 1480-1880 rubles. (at the rate of the Central Bank of the Russian Federation for July 2012), average - 1,680 rubles. Installation cost - about 1000 rubles.
The cost of heat for the specified room per month (year, 25 years) at a monthly consumption rate of 0.018 Gcal / m 2(averaged over the year) and the cost of heat 1400 rubles / Gcal	0.018 Gcal / m2 * 20 m2 * 1400 rubles / Gcal = 504 rubles / month or 6048 rubles / year or 151 200 rubles. for 25 years
Savings for the billing period (while reducing heat consumption by 35%)	RUB 151,200 * 0.35 - (1680 rubles + 1000 rubles) = 50 240 rubles.
Average savings per year	RUB 50 240 / 25 years = 2010 rubles / year
Approximate payback period	less than 1.5 years
Net savings for each ruble invested over the entire service life	50 240/2680 = 19 rubles.

It is noteworthy that even if we use average savings of 10-15% in the calculations (i.e., assume that the inhabitants of the apartment do not care about reducing payments for heat), it will still turn out that the thermostat completely pays for itself over the life of 7 times!

In conclusion, it should be noted that without the automation of the heating system, the installation of automatic radiator thermostats and the transition to apartment heat metering, other measures to save it on the scale of a single apartment, most likely, will not give tangible economic results. After all, simply by insulating windows, doors and walls, the tenant will receive the same amount of heat intended for his apartment according to the project, and the “saved” gigacalories will only bring inconvenience, increasing the air temperature to uncomfortable. As a result - heat overruns, open vents and, as a result, colds. If the heating point of the building is properly automated, only in this case it is possible to talk about saving by replacing the windows in the apartment.

If the supply of heat to your home is automated and you already have automatic radiator thermostats installed, then it’s time to think about other ways to reduce its consumption.

Energy saving windows

After installing thermostats, the next natural step towards saving is the replacement of ordinary windows with energy-saving ones, for example, plastic ones.

“Installation of modern energy-saving windows allows reducing heat losses by more than 30-40%,” says Rafik Alekperov, Technical Director of PROPLEX. - This effect is achieved due to several design features of plastic windows. First of all, PVC profiles, from which frames and sashes are assembled, have up to 4-5 air chambers, which increases the thermal resistance of the structure. Instead of single glasses in plastic windows, double-glazed windows are used, consisting of 2-3 glasses, hermetically glued into a single block with the formation of air chambers. To further reduce heat loss, glass with a low-emission coating is used in the glass unit, and the chambers are filled with inert gases (for example, argon). In addition, up to 2-3 frost-resistant rubber seals are provided between the frame and the sashes, which prevent blowing and drafts. "

We have made an estimate of the savings for a standard 1150x1420 mm window in a 137 series house. At the same time, it was considered that the average outside air temperature is -3.6 ° C, and the duration of the heating period is 213 days (data for Moscow according to SNiP 23-01-99 "Construction climatology"). Performance characteristics of energy saving windows are provided by PROPLEX.

	Regular window	Energy saving windowPROPLEX
Life time	(VSN 58-88 (r))
Estimated period (service life of energy-saving windowsPROPLEX)
The cost of a window with the specified parameters for the billing period (including installation)	cost of windows 1.5 * 5000 rub. = RUB 7500 installation cost 1.5 * 3000 rub. = RUB 4500	(including installation)
Reduced resistance to heat transfer (for Moscow)	0.38 m2 ° C / W (SNiP 23-01-99)	0.75 m2 ° C / W
Heat loss and heat costs for Moscow for the season (Heat loss = temperature difference inside and outside * window area * duration of the heating season / coefficient of resistance to heat transfer)	28.6 ° C * 1.63 m2 * 213 days / 0.38 m2 ° C / W = 627 kWh = 0.54 Gcal 0.54 Gcal * 1400 rubles / Gcal = 756 rubles.	28.6 ° C * 1.63 m2 * 213 days / 0.75 m2 ° C / W = 318 kWh = 0.27 Gcal 0.27 Gcal * 1400 rubles / Gcal = 378 rubles.
Savings for the billing period		(756 rubles / year * 60 years + 12,000 rubles) - (378 rubles / year * 60 years + 12,000 rubles) = 2,680 rubles.
Average savings per year		RUB 22 680 / 60 years = 378 rubles / year
The approximate payback period for the additional costs of installing an energy-saving window
Net savings for each ruble invested over the entire service life		22680/12000 = 1.9 rubles.

So, if we analyze the cost of various types of windows, taking into account installation in the long term, it turns out that ordinary windows are not at all cheaper than energy-saving ones. Accordingly, the latter give, albeit relatively small in monetary terms, but net savings. Due to these savings, the difference in the cost of conventional and energy-efficient windows is fully paid off after 10 years. Moreover, one should not forget that modern windows are not only energy saving, but also good sound insulation.

Heat recovery ventilator

Experts have long noticed that most of the heat escapes from the house not through windows and walls, but when the premises are ventilated. “According to German studies in the field of energy conservation, 50% of the heat spent on heating an average home is wasted, evaporating through open vents and transoms,” explains Dmitry Tsekhotskiy, commercial director of Blizzard Lufttechnik Russia.

However, airing with the help of vents in the gas-polluted atmosphere of a modern city often becomes meaningless. Increasingly, special devices are used for this purpose - automatic ventilation panels, which not only renew the air in the room, but also filter it from harmful impurities and street odors. In addition, such devices protect the house from street noise. And the most "advanced" models are also equipped with a recuperator so that heat is not emitted into the street with the exhaust air. We will test the effectiveness of this energy-saving solution using the example of the Blizzard Lufttechnik Standard ventilation panel.

When calculating for our 20-meter room with 2.7-meter-high ceilings, we proceeded from the assumption that the air in the room should be renewed hourly, i.e. the panel operates with a capacity of 60 m 3 / hour (maximum - 100 m 3 / hour).

Lifetime
Installation and Maintenance Cost	1648.5 euros as standard = 64,200 rubles. replacement of filters every 3 years - 2 * 8 * 27 euros = 432 euros = 16 800 rubles. replacement of 2 engines in 15 years - 350 euros or 13 630 rubles. TOTAL: 64 200 + 16 800 + 13 630 =
Heat consumption for heating a room per month for the period of operation at a monthly consumption rate of 0.018 Gcal / m 2(averaged over the year) and the cost of heat 1400 rubles / Gcal	0.018 Gcal / m2 * 20 m2 * 12 * 25 = 108 Gcal
Heat loss due to ventilation through the vents (50%) in Gcal and rubles for the service life	108 Gcal * 0.5 = 54 Gcal 54 Gcal * 1400 rubles = 75 600 rubles.
Potential heat savings (recovery efficiency 76%)	RUB 75 600 * 0.76 = 57 456 rubles.
Payback	(RUB 57 456 / RUB 94 630) * 100% = 61%

Of course, the panel will not pay for itself completely, but this was not supposed to be, because energy saving is rather an accompanying function of this device. However, due to the heat savings on the scale of our relatively small room, it pays for itself by almost 2/3, which is a good result. By the way, if you use the panel at full capacity, i.e. ventilate a room with an area of ​​40 m2, then the resulting heat savings will be 1.6 times higher than the cost of equipment.

Energy Saving Wallpaper

In search of solutions that allow us to save heat, we came across such things. Let's try to evaluate the savings that ERFURT KlimaTec wallpaper provides. Unfortunately, the manufacturer does not provide any data on the heat transfer resistance of its materials, suggesting instead to use the calculator on the website to calculate the savings. By entering the initial data of our room in a modern apartment building, we received savings of 60 euros or 2340 rubles. for 5 years (this is the warranty period). If we assume that the service life of the wallpaper is not limited by the warranty and is, like ordinary vinyl, 20 years, then we get 9360 rubles. savings.

And what will the wallpaper themselves cost and how much more expensive will they be than ordinary vinyl ones?

Thus, in the conditions of a modern apartment building, energy-saving wallpapers do not pay off their cost, although they provide a certain amount of heat savings.

Part 3. Saving water

Another item of the family budget is the cost of hot and cold water.

Economy hand shower

You can save water in different ways, for example, by reducing its consumption when taking a shower. This can be done with shower heads equipped with an economy button, such as the GROHE Rainshower Icon: simply move the button to the economy position and water consumption will be reduced by up to 40%. Let's estimate what this will "result" in, taking the "average" tariff for the Russian market at 20 rubles per cubic meter of cold water, 100 rubles - per cubic meter of hot water and 15 rubles - per cubic meter of water disposal.

Lifetime of the economical shower head
Shower head cost	2500 rubles
The amount of water taken daily for a shower	150 l (two adults and a child)
The cost of taking a shower (including drainage) for the entire life of the shower head (assume that hot and cold water are mixed in equal proportions)	(0.15 m3 * 15 rubles / m3 + 0.075 m3 * 100 rubles / m3 + 0.075 m3 * 20 rubles / m3) * 365 days * 20 years = 82 125 rubles.
Lifetime savings (40%)	RUB 82 125 * 0.4 - 2500 rubles = 30 350 rubles.
Average savings per year	RUB 30 350 / 20 years = 1517.5 rubles.
Payback period	about 2 years
	30 350/2500 = 12.1 rubles.

Economical mixer

A similar way of saving is the thermostatic shower mixer with an economy button, like the GROHE Allure Brilliant. True, the water consumption here is already halved, and it's not just about taking a shower.

Lifetime of the economical mixer
Mixer cost
Daily water consumption
The cost of water (including the cost of wastewater disposal) for the entire life of the mixer	(0.21 m3 * 15 rubles / m3 + 0.105 m3 * 100 rubles / m3 + 0.105 m3 * 20 rubles / m3) * 365 days * 20 years = 114,975 rubles.
Lifetime savings (50%)	RUB 114 975 * 0.5 - 17,000 rubles. = RUB 40,488
Average savings per year	40 488 rubles / 20 years = 2024 rubles.
Payback period	more than 8 years
Savings for each ruble invested over the entire service life	40 488/17 000 = 2.4 rubles.

So, let's summarize.

• The Danfoss radiator thermostat is the absolute leader in the energy saving rating. The net savings are 19 rubles for each ruble invested.
• Economical shower head - 12.1 rubles of savings for each invested ruble.
• Fluorescent lamp - 7 rubles savings for each ruble invested.
• LED lamp - 5.4 rubles savings for each ruble invested.
• Economical mixer - 2.4 rubles of savings for each invested ruble.
• Energy-saving windows - 1.9 rubles of savings for each ruble invested.
• Halogen lamp - 0.87 rubles of savings for each invested ruble.
• Ventilation panel with heat recovery - due to heat savings, it pays for itself by 61%. When used in larger rooms, it pays off completely.
• Solar mini-power plant - pays off 28%. The use of this solution today is advisable only with frequent power outages or with a lack of power.
• Energy saving wallpapers don't pay off.

A special "People's Choice Award" in our rating is awarded to the ventilation panel, with the help of which we managed to obtain the largest savings in absolute terms: 57,456 rubles.

As for the payback period, there are clear three leaders here: fluorescent and halogen lamps, as well as an automatic radiator thermostat.

Today they are one of the most pressing issues in the field of construction. And this is quite understandable, because at the present time the world has paid attention to the problem of saving energy resources - buildings, structures, and other building and engineering structures. One of the latest developments in the construction market is energy-saving (heat-insulating) paint - a product intended not only forin the house, but also to prevent many other negative phenomena.

What are energy saving paints

Energy-saving paint is a new generation of composite paint, which was invented back in the 70s of the XX century by American designers who create spacecraft "Shuttle". The main goal of the scientists was to create a new ultra-modern material that could simultaneously withstand low temperatures in space and high temperature regimes when a ship passes through the atmosphere.

So, as a result of multiple tests, a new one was developed - an energy-saving paint, consisting of a polymer matrix and special fillers in the form of hollow microscopic particles (microspheres). The diameter of one microsphere is about 10-200 microns, the wall thickness is about 0.5-2 microns. The appearance of the microspheres resembles a powder. The general characteristics of an energy-saving composition depend on the size of the particles, their quantity in the paint and the material from which they are made.

The energy-saving properties of the coating are provided due to the polymerization of the composition: after drying, it turns into an elastic and dense membrane substance. Microspheres in the membrane reflect and dissipate heat fluxes on the painted surface. They are able to reflect about 80% of visible sunlight and about 90% of infrared radiation. Thus, the paint performs the function of "climate control", that is, it prevents cold from entering the room in winter and hot air in summer.

In the 80s of the XX century, it was decided to use advanced space technologies for “domestic” purposes. The first patented one, which was proposed for use in residential and commercial construction, consisted of hollow ceramic microparticles and a liquid polymer composition. Energy-saving paints appeared on the European construction market in the 90s of the XX century, and the first production of such paints in Europe was established in Germany in 2002.

Modern energy-saving paints

Currently, many manufacturers produce energy-saving (LLC "Special Technologies", JSC "Gomelstroymaterialy", the company "Termalkom", etc.). Such paints have many varieties, differing from each other in type, composition and some performance characteristics - these can be energy-saving paints containing microspheres of glass and ceramics; aerosol paints; paints containing insulating putty, etc.

Modern energy-saving paints are antistatic, non-allergenic, do not require labor-intensive installation work, are resistant to atmospheric precipitation and ultraviolet radiation, have high decorative properties and have a long service life - from 10 years and more. Such paints can be applied to various types of surfaces: drywall, wood, metal, brick, concrete, etc. Moreover, a 1 mm thick layer of energy-saving paint has the same thermal insulation properties as a 2.5 cm thick mineral wool layer.

Where are energy-saving paints used?

The use of energy-saving paints in construction makes it possible not only, but also to protect the structure from corrosion, heating and condensation, which significantly reduces operating costs and allows less frequent repair work. In addition, energy-saving paints can serve as an excellent material for finishing the facades of houses, since from an aesthetic point of view, they have a rather attractive appearance.

Energy-saving paints are used for painting the external and internal surfaces of the enclosing structures of industrial and residential buildings and structures, loggias, cornices, slopes,, hangars, refrigerators, containers, trailers, garages. It is advisable to use such paints in poorly heated, damp rooms - bathrooms, changing rooms, showers and bathrooms, as well as in rooms with special temperature and humidity conditions - swimming pools, freezers, etc. In addition, energy-saving paints are used in the construction of bridges, the manufacture of tanks for storing water, gas, oil and petroleum products, the arrangement of pipelines and air conditioning systems.

Energy Saving Supplements

Relatively recently, a new ceramic energy-saving additive has appeared on the construction market, which can be added to a conventional one and thus obtain a heat-insulating material. This additive is in the form of a dry white powder, which consists of ceramic granules with a size of 30-100 microns. The powder is an absolutely non-toxic and environmentally friendly material with inertness, long shelf life and a melting point of about 1800 ° C.

In order for the usual one to acquire thermal insulation properties, it is necessary to add an energy-saving powder composition to it at the rate of 110 g per 1 kg of paint. In this case, the consumption of the finished composition will remain the same as indicated by the manufacturer on the paint can. The energy saving supplement is sold in bags (20 kg) and packs (110 g and 550 g).

The energy-saving additive can be mixed not only with, but also with other composite materials for exterior and interior decoration of the house. By the way, on the basis of such an additive, unique insulating energy-saving wallpapers are produced, which serve as excellent thermal insulation of the room and smooth out some irregularities in wall coverings. Energy-saving wallpaper can be glued under normal wallpaper.

Energy-saving paint technology

Energy saving products should be applied to a dry, clean surface using a spray gun, brush or roller. Substrate preparation is carried out according to the requirements GOST 28196-89 (clause 6.3.), that is, exactly the same as when working with water-dispersible compositions.
