Located in Berlin’s Kreuzberg neighborhood, the GSW Headquarters consists of an ensemble of five distinct architectural volumes. The building also houses Checkpoint Energy, which is the city’s spot for the citizens to consult on energy saving, thermal insulation, renewable energies, switching energy suppliers and more! A non-profit initiative by the Federal Ministry of Economics and Technology and the Consumer Federation, the center — which charges €5 for 30 minutes — gets its own advice from a network of experienced architects, engineers and physicists. Aiming for climate protection and resources conservation, this energy-consulting center is an important step forward towards an energy-conscious future.

Located on the Checkpoint Energy’s west side is the GSWHeadquarter’s building, which glows in different hues of red and pink. Designed by Sauerbruch Hutton, this passive renovated 22-story office building was designed to get free cross ventilation and passively control its energy usage. It is said to be the world’s first thermally-flued tall building and can have natural ventilation for up to 70 percent of the year, making it more sustainable and economical to run.
