Many would be happy to cut their heating costs, but do not know how to do it. Refuse from the usual household appliances and gas supply? This is not an option. This is no longer needed, because at the moment there are projects of buildings that have modest energy needs, so they are gaining increasing popularity. An energy-saving house is already a reality, not a fiction. You can consider its device.
Energy-saving house is a structure, not only dependent on external energy sources, but also capable of serving as such a source. There is a good thermal insulation, obtained due to the heat of the building itself, as well as surrounding areas. Primary energy coming from external sources is consumed to provide hot water, heating, electrical appliances, and lighting in this structure 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-saving house.
It is not necessary to build such a dwelling 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 involves the use of natural heat sources to the maximum, for example, from solar radiation. That is why it is necessary to properly locate the doorways, limiting their number from the north side or completely eliminating. Energy-saving house has an optimal arrangement of premises. It is important to remember that significant glazed areas on the south side help to get heat from the sun's radiation. But in summer they often cause overheating of the house. If we envisage shading elements in the project, this will not happen. These can be canopies that are pushed beyond the contour of the structure. It is assumed that they will prevent the arrival of sunlight in the summer, when the sun is located high above the horizon. However, they should not interfere with the winter rays, when the luminary hangs low over it. The use of rolling 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 the deciduous trees on the south side , then in the summer they will shade the house, and in the winter they will allow you to receive heat from the sun, as the leaves fall off. On the northern side, it is advisable to plant plants capable of protecting the structure from the wind all year round. Conifers cope with this task just fine.
The prefabricated wooden house is also able to become energy-saving, if everything is carefully thought out. Walls, floors, floors and roof must be protected from heat leakage. This can only be done by using thick layers of insulation. The thickness of the thermal insulation layer for external walls should not be less than 20 centimeters. The floor requires at least 30 centimeters of such material, and for the roof - not less than 40.
