With the modernization of the office building at Enggasse 3 in Cologne, Art Invest Real Estate has put to use new technical solutions for office space lighting in its own headquarters.
The functional lighting is designed to align with the circadian rhythm. The lighting control system adjusts the color temperature and illumination intensity to match the progression of the day. The program can be overridden by the user to adjust the light in a given room. The glare-free and homogeneous direct light, the authentic appearance of the indirect components and the mixing of the two color temperatures were determined specifically for this project in cooperation with the manufacturer, thus jointly advancing the product's development

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.

Haus Huth is the only building on Potsdamer Platz originating from the German Empire that has survived the tumultuous history of Berlin virtually unscathed. It currently houses the Berlin office of the DaimlerChrysler concern.
The house, unlit until 2004, was hauled out of the darkness by the lighting design of Kardorff Ingenieure and now stands with presence in its old place surrounded on all sides by modern architecture.

The structure of the "MY.B" facade, with the building's striking soffits and length, led to the idea of illuminating the facade using laser projection.
The soffits stick out as the prominent structural feature of the building's form and serve as the perfect backdrop for the glancing views along the front. The dynamic of the commuters coming into the city in the morning and leaving in the evenings going northward can be experienced in the similar movement of the light.
The newest generation of laser technology and automation are used on the "MY.B" building.
Depending on the situation, the lighting can vary between restrained static motifs and very dynamic geometries with long-distance effects.
The system consists of two laser projectors that are integrated into bespoke outdoor cases that have been mounted on the upper section of the columns.
Power consumption is about 90 to 150 Watts max. per projector, which is, for this specific use, about 50% below the requirements for LEED Gold or Platinum Certification and can therefore be considered as the most energy-efficient facade lighting.
