Polar Bear House from X-TEND & I-SYS - sustainable building in Baden-Württemberg

Minimum energy, maximum safety

In order to actively promote the conservation of natural resources, the polar bear house in Kirchheim unter Teck was designed and realized as a passive house. The polar bear house is recognized holistically and above all sustainably by the builders with the adjectives. The name polar bear house is symbolic of the efficient energy concept of the white predator.

For the polar bear house built in Baden-Württemberg, a quick look was taken into the Austrian Vorarlberg near the border. The ecological guidelines applicable there were the basis for the choice of building materials. Each material was also examined for its energy consumption during manufacture. The materials used, including both the X-TEND CXE stainless steel cable network and the I-SYS stainless steel cable from CARL STAHL ARCHITEKTUR, stand for sustainability, environmental protection and the best quality.

X-TEND as protection against the elements

In the passive house in Kirchheim unter Teck, the X-TEND stainless steel rope net not only fulfills the function of fall protection, but also serves as a variable mesh stainless steel net as variable protection against wind and weather. In addition, the X-TEND secures the facade and the staircases as a visually appealing design element.

The facades of the polar bear house, which are covered with the X-TEND stainless steel cable network, consist of prefabricated wall elements that are exactly one floor high. Inlaid Halfen rails fix the elements to the reinforced concrete skeleton. The concrete-gray building elements are visually extensively upgraded with wooden formwork made from silver fir (Black Forest).

Excellent passive house

Both commercial and residential units can be found in the polar bear house. Underfloor heating is installed in all apartments. The soil serves as a heat source for this. On the roof of the polar bear house you will find a photovoltaic system with which the goal of being self-sufficient will soon be achieved.

The polar bear house with its X-TEND fuses was awarded at the Expo Real. In addition to eleven other innovative projects, the German Society for Sustainable Building, DGNB for short, recognized the house in Kirchheim unter Teck as particularly climate-positive. The special features worthy of a prize include ...

  • the selection of sustainable materials,
  • the cooling and heating surfaces in the concrete ceilings,
  • the brine water heat pump for climate control and
  • that Wood as the predominant design feature.
