Many would be happy to reduce their heating costs, but do not know how to do it. Refuse conventional household appliances and gas supply? This is not an option. This has already disappeared, as at the moment there are projects of buildings with modest energy needs, so they are gaining more and more popularity. An energy-efficient home is already a reality, not a fiction. You can consider its device.
An energy-saving house is a structure that not only depends on external sources of energy, but is also capable of serving itself as such a source. There is good thermal insulation, obtained due to the heat of the building itself, as well as the surrounding territories. The primary energy coming from external sources is consumed to provide hot water, heating, electrical appliances, as well as lighting in such a building. Naturally, the prospect of minimal use of funds looks very tempting, but it is worth analyzing all the advantages and disadvantages if you are interested in an energy-saving house.
Such a dwelling is not necessary to erect in the form of a traditional rectangle. A square-shaped building is considered a great option. The main feature of an energy-saving house is that it provides for the use of natural heat sources to the maximum, for example, from solar radiation. That is why it is necessary to correctly position the doorways, limiting their number on the north side or completely eliminating it. Energy-efficient house has an optimal layout of the premises. It is important to remember that large glazed areas on the south side help to get heat from the radiation of the sun. But in the summer they often become the cause of overheating at home. If shading elements are included in the design, this will not happen. These can be canopies that are extended beyond the contour of the structure. It is assumed that they will prevent the entry of sunlight in the summer when the sun is high above the horizon. However, they should not impede the winter rays when the star hangs low above it. The use of moving curtains in the summer is a good alternative.
This is not all
energy-saving technologies for the home. Reasonable use of the territory and green spaces also gives a good effect. If you plant
deciduous trees on the south side
, then in the summer they will obscure the house, and in the winter they will allow you to receive heat from the sun, since the leaves will fall off. On the north side, it is advisable to plant plants that can protect the structure from the wind year-round. Conifers cope with this task just fine.
A prefabricated wooden house can also become energy-efficient if everything is carefully thought out. Walls, ceilings, floors and the roof must be protected from heat leakage. This can only be done using thick layers of insulation. The thickness of the insulating layer for the outer walls should not be less than 20 centimeters. For the floor requires at least 30 centimeters of such material, and for the roof - at least 40.
