With this new building, E.ON Ruhrgas AG sets an example in terms of energy-efficient urban architecture. The main energy expenditure is reduced by 40% when compared to an administrative building following the traditional standard. The two elliptical office towers are each 63 m high and are connected by a glass atrium flooded with light.

In 2005 at the end of the renowned Königsalle in Düsseldorf, a 23-floor high-rise for Ernst&Young was built. Our light concept for the building includes the importance of its impact
from a distance for the entire urban area. The dynamic basic design of the structure is underlined by a linear lighting pattern that becomes fainter as the lines travel toward the opposite ends. The project was overseen by our team during all phases ranging from the overall effect at night and the lighting of the workstations to the subterranean parking area and the daylight planning.
