Under daylight conditions, the transparent facade appears dark and reflects its surroundings. Indoor lighting allows the observer to see into the building. Ceiling washlights in the indoor area emphasise the ceiling surfaces and increase the overall impression of interior brightness at night. The facade construction is silhouetted. Lines of light in the ceiling area of the individual floors underline the horizontal building structure. Uplights emphasise the vertical elements of the facade.

The visual perspective from the ground makes the lighting effect of the indoor area appear larger with uplights than with downlights. Dazzling the users of the indoor area should be avoided. Luminaires shining into the indoor area will impair the view out of the building.
