Kö-Bogen

Aesthetical down to the smallest detail
The Kö-Bogen in Düsseldorf: With its curved shapes this complex of buildings constitutes an urban planning highlight. Star architect Daniel Libeskind has combined white natural stone and glass. However, apart from smooth fronts there are also diagonal cuts on two sides of the façade into which hanging gardens have been integrated. A bold idea requiring sophisticated implementation. On such an exceptional building every detail counts. Everything has to be just right, from the concept to the quality of the materials. This is where TTC Timmler and ADO Lights make their contribution – with high quality products that fit in perfectly.

This includes unobtrusive slotted drains made from stainless steel to accentuate building outlines with their integrated illumination. Homogeneous grating design to drain the façades all around the Kö-Bogen underlines the aesthetically pleasing overall impression. In the entrance areas the bar spacing was chosen in such a way as to be kind even to stiletto heels. Furthermore, the intelligently finished surfaces of the linear gratings on the doors provide an anti-slip effect. In combination with the embedded doormats this prevents as much dust and other particles as possible from being walked in to the building.

The green inner courtyards are a real highlight: Instead of a comprehensive illumination the atmospheric lighting provides well aimed accent lighting. This is achieved through light lines on the planters – an effect that can also be found in the outdoor area around the intake structures. The trees in the inner courtyards are also put in an atmospheric limelight. This is done using spotlights because their low thermal output does not affect the plants.

The Kö-Bogen won the prestigious MIPIM award. Even from afar the observer can see why but also when he takes a closer look.

Task
Accentuated, partial illumination on the edges of the intake structures plus light effects in the two courtyards.

Solution
Intake structures serve the ventilation requirements of a building, hence they are practical – but at the same time very visible. 42 m of LED-LightLines in warm-white, integrated in the slotted channels, make the two intake structures of the trendy Kö-Bogen look like luminous objects.

In the courtyards, which do not have illumination in the traditional sense, approximately 100 m of LED-LightLines trace the contours of the planters with a warm-white light. This results in an exceptionally harmonic bond between high tech and nature. This masterful manoeuvre is part of the overall concept: Since the bridge linking the two parts of the building is indirectly illuminated using LED-LightLines. In addition, twelve LED spotlights are used to strikingly highlight trees in planters. The result is an unusual ambience and its light mood also serves as an eye-catcher for people working in the adjacent offices.
