Lighting compensates for the different daylight situations throughout the day and the year, while accentuating the sequence of different rooms.

A continuous three dimensional band of light in the atria helps to unify the space and supports a sense of depth from the different points of view. Elements from the same conceptual family can be found in all conference and meeting rooms. Vertical lines illuminate corridors and staircases. Luminaires in the breakout areas, canteen and cafeteria have a decorative character, for a more relaxing atmosphere.
