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.

Material studies were performed for the foyer and the special areas of Tower 1. The planned use of high-grade steel wall and ceiling liners was assessed in terms of light actinism. The images show in reflections of the luminaires how the direction of rolling and the surface pattern influence the light reflection.

The project was not realized.

In 2002 on the Theodor-Stern-Kai am Main, with a direct view of the Frankfurt skyline, the new office and service center for nine Allianz insurance companies with approximately 2,500 employees was constructed. Kardorff Ingenieure designed the lighting for all of the special areas and the illumination of the facade.

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 89-meter high Sky Office introduces itself as a new landmark on the Kennedyallee in Düsseldorf and offers a splendid view. The design by Ingenhoven Architects distinguishes itself through its high degree of transparency, overall sculptural shape, and roof as a crowning finish.
