Brandenburg State Parliament

ISOLAR SOLARLUX®

  • Government building combines history and modernity

    The new building to house the Brandenburg Parliament is closing a decades-long gap in the urban landscape at the heart of Potsdam. The modern seat of government at the Alter Markt square in Potsdam cost around EUR 120 million. It was built within the perimeter and on the outlines of the former city palace and its baroque facade is also reminiscent of the building that once stood there. Solar control glazing with integrated alarm function from glass producer arcon provides even more security and energy efficiency and ensures that the building is flooded with light.

    The new Brandenburg Landtag combines the outer appearance of a historic palace with the interior of a modern parliament building. The five-storey building with a usable area of 15,000 m2 houses the plenary chamber, various conference and meeting rooms and other facilities.

  • Stringent security requirements

    As a government building, the new build had to meet special security requirements. To ensure these could be realised, the building features among other things 1,600 m2 of impact-resistant sunbelt platinum solar control glass from arcon. Using a screen-printing process, metal conductor tracks were applied to the functional glass. They are connected to the building’s alarm system and register, for example, if intruders try to gain unauthorised access through the windows.

    Energy efficient glass facade saves heating costs

    With an energy transmission of 40 percent, the solar control glass also contributes to the energy efficiency of the building. Even on sunny days the inside of the building is pleasantly cool. There is no need for additional air conditioners or shade systems on the facade. The energy used for heating the interiors on cool days is substantially reduced by the special glass. As very little heat escapes, this also saves energy costs. The high light transmission ensures that the building is flooded with light, a key feature of the interior architecture.

    The sunbelt platinum solar control glass was installed e.g. in the numerous casement windows that were designed to look like the windows of the former city palace. This is why the outer frames of the windows are in wood. The solar control glass blends harmoniously into the wooden window frames, in part due to the low outer light reflection of a mere 11 percent.

    “Whether produced in sheet format or cut sizes, the various glass elements of the building show how through innovative special glass the bridge between baroque facade design and maximum functionality can succeed,” says Albert Schweitzer, Plant Manager at arcon.
