The twin towers of the Highlight Tower in Munich can best be described as a funnel of endless reflecting surfaces. The buildings are equipped with blue static luminous marker lights located at the edges of the building on each floor, accentuating the cubature of the towers at night. Fluctuating light in the pedestrian bridges and the glass lift cabins emphasizes the few structural connections between the towers. A multitude of light reflections and refractions create the impression of endless rooms filled with changing coloured light. The dynamic lighting integrated into the access elements accentuates the architectural form. The office lighting for this project is developed as combined ceiling illumination and functional workplace lighting supports the perception of the spatial structure of the building. The brightly illuminated ceilings of the office rooms define the architecture and contribute to a high user-friendliness of the building.
