Extensive modernization of the former Debis building with the Renzo Piano Building Workshop. Kardorff Ingenieure supervised the DGNB gold-certified project from planning to execution for the 22-storey, 106 meter-high office tower, the spectacular atrium with adjacent lobbies and entrances, as well as the new exterior illumination. Already completed in 2015, the Sky Office showroom is located on the eleventh floor.

The multistorey administrative building completed in 1959 underwent thorough refurbishment to meet contemporary expectations of a corporate headquarters. The building received two new entrances with flying roofs that noticeably complement the older building.
The office lighting design has linear lighting fixtures integrated into the ceiling. The arrangement of luminaires underscores the lightness and refinement of the building in its nocturnal effect. At our suggestion, the luminaires are placed in a channel custom designed by us to include all of the building automation: sprinklers, loudspeakers, ventilation outlets, etc. The space in which to position all of these elements was very constricted, making their placement in the channel a particular challenge that had to be closely coordinated with the architects and building technicians. As a result, the ceiling is now extremely clear in its structure and remains free of any other fixtures or installations.

The architectural ensemble at Alter Wall 2-32 is composed of five buildings directly next to Hamburg's City Hall. The historically listed block was renovated to house shops, restaurants and high-end office space, including a large interior courtyard. Central importance has been given to the new Bucerius Passage, an arcade with bridge that now serves as a new and important passageway in Hamburg's city center.
We designed special lighting fixtures for this arcade: a pendant luminaire of a hyperboloid construction that is distinguished by interlaced metal bars from which light rings hang. Hidden in these rings are fixed light points that illuminate the floors and ceilings of the passageway and colonnade. The dimensions of the lighting fixtures vary widely depending on their position in order to match the given spatial dimensions.
These large-format light objects create a light motif visible from afar that harks back to the grand historical Alster arcades and gives this special place a festive atmosphere in the evenings.

The research and administrative building for Procter & Gamble is located in Schwalbach am Taunus. The labs and open office areas are arranged around a glass-roofed atrium. Kardorff Ingenieure Lichtplanung was responsible for the daylight design of the facade, atrium and roof.

The former electric power substation now listed for historical preservation has become a popular venue in Berlin Mitte since 2005. The closed character of the industrial structure was transformed into a light, modern office building opening out into the city. Kardorff Ingenieure designed the entire interior and
exterior lighting.
