Heliotrope - the world's first "solar" house, which produces energy

Now many architects of the world, including the most famous ones, are developing the idea of ​​creating residential houses and office buildings with zero or almost zero energy consumption. Some enthusiasts invest a lot of money and effort, and build their own "zero" houses. For example, not so long ago, an American invested 300 thousand dollars (which is not so much for such projects), and built himself a house that does not really consume energy, and is not connected either to the water supply or to the electrical grid. The house provides itself ... But what would you say if you heard that there is already a real building that generates energy five times (!) More than it consumes?

Fantastic, I thought, having read about such a house here . It turns out that it is not fiction at all, but the reality of today. This house is really very futuristic, so to speak - it uses the maximum amount of solar energy, rotating with the sun. Thus, solar panels always get the maximum amount of light, and advanced daylight systems allow residents not to turn on the extra light.

In addition to solar panels, thermal tubes are also used for water heating (there are a lot of such systems in Turkey - almost every house and hotel is equipped with similar water heating systems).

In general, this system allows this creation of architects to be counted as a real “nulevik”. In addition, the system produces energy five times more than it can consume - and yet not a single building can still boast the same. In the United States and other countries, as is known, such systems can be connected to the power grid of an energy company, which pays a coin for every watt invested. Thus, the inhabitants of the house can not only spend nothing on electricity, but also earn.

This miracle is located in Germany, the city of Freiburg. Perhaps its creator, Ralph Disch, would never have built anything of the kind if the government hadn’t been planning to build nearby nuclear power plants 25 years ago. The architect made every effort to prevent this, and succeeded. As a result, Helitrope also appeared. The building rotates 180 degrees, solar panels of 6.6 kW / h are installed on the roof.

As already mentioned, there is also heating of the water on the roof, which is used to heat the house during the cold season and into the bathrooms and showers of the residents of the building. And yet - the building collects rainwater, giving to the needs of the inhabitants of Helitrope.
