Many would love to cut their heating bills but don't know how. Abandon the usual household appliances and gas supply? This is not the way out. This is no longer necessary, since at the moment there are projects of buildings with modest energy needs, due to which they are gaining more and more popularity. An energy-saving house is already a reality, not a fantasy. You can consider his device.
An energy-saving house is a structure that not only depends on external sources of energy, but is also capable of serving as such a source itself. There is good thermal insulation, obtained due to the heat of the building itself, as well as the surrounding areas. Primary energy from external sources is consumed to provide hot water, heating, electrical appliances, and lighting in such a building is much less. 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-efficient home.
Such a dwelling does not have to be built in the form of a traditional rectangle. A building that has a square shape is considered an excellent 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 them. An energy-saving house has an optimal location of the premises. It is important to remember that large glazed areas on the south side help to receive heat from the sun's radiation. But in the summer they often cause the house to overheat. If you provide shading elements in the project, then this will not happen. These can be canopies that are extended beyond the contour of the building. They are supposed to block out the sun's rays in the summer when the sun is high above the horizon. However, they should not interfere with the winter rays when the luminary hangs low above it. Using movable curtains in 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 summer they will shade the house, and in winter they will allow you to receive heat from the sun, as the leaves fall off. On the north side, it is advisable to plant plants that can protect all year round.building from the wind. Conifers do this just fine.
A prefabricated wooden house can also become energy efficient if everything is carefully thought out. Walls, ceilings, floors and roofs must be protected from heat leakage. This can only be done using thick layers of insulation. The thickness of the heat-insulating layer for external walls should not be less than 20 centimeters. For the floor, at least 30 centimeters of such material is required, and for the roof, at least 40.
