How to build an Energy-Efficient House?
An Energy-Efficient House is not just a trend or a way to save money, it’s a real must if you want your home to be practical in the future. That is why we are going to tell you a little bit about it today.
Some basic things to think about to build an Energy-Efficient do.
The energy consumption of the house for heating can be reduced by placing rooms. So that only those with an auxiliary function are located on the north side, for example, storerooms, a wardrobe, a technical room, or a garage. If the heating system is properly adjusted, it can be kept at lower temperatures than the occupants without compromising comfort. In these premises, it is also easier to reduce the number of windows or do without them altogether.
Since most heat escapes through the walls and the roof, they need to be built of high-quality materials and carefully insulated. It does not matter whether we opt for cellular concrete, ceramics, expanded concrete, or silicate. What is essential is that the walls have the appropriate thermal parameters. Energy-saving houses are usually built as two- or three-layer or skeleton houses. Which construction facilitates the application of very thick thermal insulation. Single-layer walls in an energy-saving house will work well if they are made of blocks with a styrofoam insert. According to the binding norms, a 20 cm thick layer of insulation of external walls with foamed polystyrene or mineral wool is sufficient.
The largest area of windows should be located on the south elevation, as on this side the energy profits from insolation will be the highest. The smallest number of windows should be designed in the northern wall, as these windows will cause the most significant energy declines. However, there may also be energy losses due to excess insolation and the resulting need for air-conditioning. To maximize energy gains and minimise losses, the south elevation should be in full sun in winter when the sun is low over the horizon but sheltered in summer. To reduce the old heat penetrating through the windows, it is worth installing external blinds. When closed at night, they can reduce heat loss by up to 40%, provided they are closed every night. To facilitate this, it is worth equipping them with electronic controls.
If you take these three basic areas into consideration when building your own home, you will significantly reduce your heating expenses, so be sure to remember them. Good luck!
