German Bundestag

Berlin, Germany

The Marie-Elisabeth-Lüders-Haus, also known as the “Luisenblock”, is the third new parliament building on the Spree, and was described by the architect Stephan Braunfels as a “leap over the Spree”.

The extensive glazing to the central connecting hall is formed as a filigree steel structure. To achieve the small dimensions of the profiles, the facade was fully suspended from the ceiling of the shell. The resulting filigree profile dimensions are formed using rectangular hollow profiles. They are executed in a specially manufactured design, as box profiles with milled surfaces and very sharply defined profile edges. The hollow profiles of the supporting facade structure are constructed as a hydraulically balanced hot water circuit. A significant part of the building’s heating is realized using this facade heating system.
