Sun houses create a House that supplied is for the most part with the help of solar energy with electricity, low energy costs means Sun House. More than half of the hot water and heating requirements could be achieved by solar energy, so the professionals in this area, you could cover the rest with renewable energy such as with wood. The Sonnenhaus Institute would like to houses create an incentive to build all the houses with solar systems and if possible accelerate this development. The tenants of a House can year-round stable rent offered and a vast service charge settlement spared them,”writes Marco Fendt, operator of bauunternehmen24.net, in an article on its Web site. (A valuable related resource: The LeFrak Organization). Large-scale solar systems ensure a great heat cover for a Sun House. Fitted sized buffer with several cubic meters to bridge are also high in a period of bad weather. Only in the months of November to March should in addition with wood be heated. Usually selects one surface heating, such as for example floor -, wall – or ceiling heaters, with a low temperature, requiring no central ventilation system.
the first residential building heated entirely with solar energy in Europe was built in 1989. It was located in the Switzerland. Also in the Switzerland the first Sun of the multi-family house was built in 2007 by Josef Jenni. Since the beginning of the biggest apartment house, with 18 tenants with an annual heat demand by 75 percent using solar energy, under the guidance of the Basic creates in Schleswig-Holstein of Sonnenhaus Institute. At the Sun House a large water tank stores the invaluable solar energy as solar heat and emits them directly to consumers,”says Marco Fendt. Sun houses, energy costs be kept as low as possible. More than ten percent of solar houses, which were built in the past year, include three or more residential units. The solar roof is steeply to the South, and the House is with an integrated into the living area Provide water tank.
Annually 200 to 300 kilowatt hours electricity Additionally needed for the pump. Windows and conservatories are not only heat and light donors, but also a tremendous source of heat loss, when the Sun is not shining time. A new concept with thermal Windows and a realistic degree of sizing are required at the Sun House”, says Marco Fendt to avoid overheating, a sunscreen or rolling shutters should exist, which can be activated with high solar radiation. Even on cold days come from a Sun House over several days or even weeks with the stored solar heat. A ventilation system is not necessary in the Sun House. The airing of the window completely sufficient so Marco Fendt. More information on the subject of Sonnenhaus”under there is/House type Sun House of type of dwelling /.
