A pedestrian subway between two building complexes should correspond to the style of the building architecture. In this case it is open, light architecture, which corresponds to daylight on account of large glass surfaces. This light effect should also be achieved in the underground connection. A graphic arrangement of wall luminaires with light emission on two sides thus accompanies the visitors through the subway. An average of 100 lx is reached at floor level. Face recognition is very good on account of the luminous energy. This makes the subway friendly and inviting. The steps of the stairs are flanked by recessed wall luminaires with asymmetrical light distribution.
