The house in which live beneficial

The modern house has to be energy efficient. This term came into circulation not so long ago, however, a lot of energy-efficient homes have been built on FORUMHOUSE - that is, such that the maximum energy savings. If the thermal insulation of the house brought to the indicators close to the absolute, and the house does not need to obtain energy from the outside, it does not have the heating system, it called passive (rather than active, which not only provides for its energy needs, but also divided the surplus with public networks). It is believed that in most regions of the country due to the climatic conditions, even a passive house can not be built, but on the experience of our customers, we FORUMHOUSE analyze what can be as close as possible to the passive energy-efficient house, whose life depends very little on electricity suppliers and heat.

Planning, layout, lighting

Energy-efficient house is often compared with a thermos of continuous, from the basement to the ceiling, the circuit insulation. And in general, when people talk about energoeffektvnosti, often mean warming. But this concept fits the whole system, including - utilities. Walls thermos home, of course, can not "breathe", for this there is a ventilation system, which is energy-efficient home will work with minimal heat loss.

Construction of energy-efficient homes are generally more expensive than conventional, so designers always keep in mind that its operation should be economically viable - then after some time, costs pay off. Therefore, experts have set themselves the task of heat saving, use of natural lighting, etc. On energy efficiency at home also affect the location and layout.

• In the north it is better to build a house in the meridional direction - it will allow a 30% increase the amount of incoming sunlight. In the south, on the other hand, the house should be placed in the latitudinal direction - in this house will be cooler, and you can save money on air conditioning.
•  Energy-efficient house is always compact, that is, without bay windows, artsy galleries, etc. The idea is to make the ratio of internal and external areas of the house as little as possible. The closer the house to the box, so it is more economical and energy efficient.

• The energy-efficient house is always provided heat buffers, the space between the housing and the cold air of the street, and even with the external environment. Thus the buffer may be a garage, and a basement, and a veranda, and high-tambours storage area, etc. It is a harsh necessity, because ...

Shabanovsv (Member FORUMHOUSE):

... in my house you will begin to pay for heating is not the average figure for the quarter. meters, in the apartment, and for a specific amount of energy that was spend on heating the streets.

• Energy-efficient house for the most part is illuminated by the sun. To do this, the most popular rooms (dining room, children's, etc.) are placed in the southern part of the house, and in the north do those who do not need a lot of light. Bedroom windows should ideally go to the East, and then in the summer of electric light in it can be not to include.
• The size of the windows in the energy-efficient house depends on what is more important: saving on heating or lighting. Usually all choose normal lighting.

Mgolovanov (Member FORUMHOUSE):

My modest 10 windows on the calculation produce as much heat as the walls. After the adoption of additional measures (shading, heat-saving curtain on deaf parts) losses amount to 20%, but not less. Mentally I'm ready - do not live in the same prison.

Thermal insulation of walls, roof and foundation

Through walls house loses up to 40% of heat, which is why so much effort is always spent on insulation. Most often, members of our portal stop at that constructing a multilayer system, for example, the outside sheathe the walls insulationFor example, rock wool, it set a reinforcing mesh and then plastered.

Andpey (Member FORUMHOUSE):

I wanted to see the house and energoeffektinym environmentally friendly, so I decided to do in the heat accumulator in the form of massive heavy walls of solid brick, ceramics, insulated exterior effective insulation.

Second Embodiment insulation walls - ventilated facade, wherein the first wall sheathed heater, and then mounted on the frame facing (stone, metal, etc.). The bottom line is that between the insulation and paneling is a space "thermal cushion", which will help prevent heat loss.

Roof insulated with the same materials as the walls. However, despite what kind of material would you prefer, a layer of insulation material having a coefficient of thermal conductivity (at equilibrium moisture content) of 0.04 W / m2K should not be thinner than 24 centimeters.

10-15% of the heat may escape through the foundation. In 2009 FORUMHOUSE its popular name - UWB - was a kind of foundation as "schwedenplatte", Swedish warmed plate. This foundation in permanent formwork of polystyrene foam It guarantees the protection of the house against heat leak. Also for insulation insulated floor - or the same materials as the walls or the filling mixtures, such as Foam or concrete, etc. granulobeton

Ventilation, heating, water

Without proper ventilation in the house-a thermos just to survive, but also to heat the street, too, do not want to. Many members of our portal has long been built into recuperators ventilation system, which allows to avoid unnecessary heating costs. It works this way: the air goes out of the room through the ventilation channels, common control with heat recovery, and it gives off heat, which heats the cold air from outside, which also passes through recuperator. Thus, the outdoor air is fresh, but becomes warm.

For hot water and heating, many members of our portal using solar collectors. Of course, self-sufficient in solar energy in our latitudes does not work, and the solar panels will pay for themselves any time soon. But they do not just increase energy efficiency at home - they are also important for self-esteem homeowner.

Leo2 (Member FORUMHOUSE):

With our net return is not considered for the cost of electricity and on losses during accidents on the network. And plus moral damages from being in a cold dark house at this time.

Solar Collectors, mounted on the roof, and simply connect to the hot water system and heating. They operate as follows: the sun heats the fluid that circulates in the collector, it in turn heats the water in the heat-insulated storage tank. On FORUMHOUSE discusses how effective these devices in the Moscow region and other regions where there is little sunlight. However, many people put them to yourself and actively communicate the use of experience. By the way, many do solar collectors themselves.

Oka90 (Member FORUMHOUSE):

For example, solar Tula that week at a temperature of -18 overboard, showed 64 in the circuit collectors.

Another popular alternative way to FORUMHOUSE home heating - heat pump. These devices are able to receive heat from the environment, our portal is often the soil and water. The heat pump includes an evaporator, a condenser, expansion valve and a compressor which are connected to a closed pipe. Actually, an example of the heat pump can be a refrigerator, but it works in reverse - cooling. Despite the fact that it is expensive equipment, it will not depend on the suppliers of heat, besides it is also possible to collect on their own - to have FORUMHOUSE step-by-step instruction.

Significantly increase energoeffektvinost home can condensing boiler - a thing, and quite often used in homes FORUMHOUSE participants. From conventional gas boilers they differ prohibitively high efficiency, because heat is taken from the flue gases and hot air which are conventional boilers leaving the chimney and, again, heated outside.

RomanX (Member FORUMHOUSE):

If the heating system to organize from scratch by kondensatnika (especially if the area is 500 m 3 +) with high-performance with the system, the event will pay for itself in a year or two.

In addition, to save resources help system "Smart Home" function - they are able to reduce the temperature in the room where there is no one, turn off the lights, make sure that the ventilation is not working in vain, if the air is fresh and so, open and close windows, etc. Energy-saving light bulbs, plumbing, which reduces water consumption by half, and will significantly reduce expenses.

Materials and equipment that increase the energy efficiency of housing, improving all the time. The world is changing quickly, and perhaps 20 years from now we will all live in a eco-friendly, energy efficient and self-contained houses. And it will be a completely different life - comfortable and free of monopolies, with a high level of awareness and respect for our planet. What we do not doubt - participants FORUMHOUSE and then find themselves in the vanguard of progress, study the most advanced technology and are successfully using them for their futuristic homemade.
