50Hertz

Both buildings form a modern, sustainable ensemble with innovative building technology, flexible working environments and striking architecture. Certified with DGNB Diamond and LEED Gold, the campus sets new standards for responsible construction in the energy sector.

50Hertz expands corporate headquarters in Berlin - Two construction projects, a strong foundation for the future

Between 2012 and 2014, Ed. Züblin AG had already realized the new company headquarters of the electricity transmission system operator 50Hertz as general contractor. The extension has now also been completed - also by Züblin

The company headquarters: architecture with character

The 51-metre-high main building was constructed in accordance with the specifications of the urban master plan. A tower-like structure with six further storeys rises above a seven-storey base with an L-shaped floor plan. The architecture uses the supporting structure as a design element: wide, white frames enclose the storey ceilings, with diagonal steel composite supports running between them to create a net-like pattern. On around 17,400 square meters of floor space, 680 workstations, seven conference rooms, a daycare centre, a café and a restaurant have been created.

The extension: functional addition with identity-creating architecture

The extension, which was completed in 2025, was also realized by Ed. Züblin AG and blends seamlessly into the existing ensemble. The architecture picks up on the design principles of the main building: Transparent facades, clear lines and a visible supporting structure characterize the appearance. The new areas provide additional offices, meeting rooms and technical areas.

Sustainability and building technology

Both buildings were planned and implemented with high standards of energy efficiency and environmental compatibility. The façades consist of multi-pane insulating glazing with solar control coating, which minimizes heat loss and reduces cooling requirements. Air conditioning is provided by thermally activated concrete ceilings, ceiling sails and displacement ventilation via the floor. These systems operate at a low temperature level and ensure a pleasant indoor climate all year round.

Certified sustainability

The company headquarters and the extension meet the requirements of the German Sustainable Building Council's (DGNB) Diamond Standard and have been certified with LEED Gold. The building shows how technical innovation, architectural quality and ecological responsibility can be successfully combined - and what sustainable construction looks like in practice.
