Visitors can reach the library with its shelves arranged in a column axis via the aforementioned foyer staircase. Filigree LED ring pendant luminaires in two sizes float above the reading tables, arranged in groups that relate to the table zones below. The pendant luminaires consist of a delicate direct light profile with a solid diffuse cover. Because the steel cables for pendant mounting are so thin and inconspicuous, the light rings appear to float as if by magic. Due to the warm-toned color palette of the interior design, the neutral white light color 4,000 K was implemented in the head building.
In the evening, the building glows softly from within thanks to its soft interior surfaces. The forecourt as an interface to the urban space was to exude security and friendliness at the same time, without showing too visible light sources. For this purpose, spotlights were attached to selected banner poles, which are hidden in the horizon of the UPE profiles. Following this principle, additional profiled masts were erected along the row of trees to Luxemburger Straße to accommodate further spotlights for lighting the square area and bicycle stands.
Depending on the opening state of the curtains in the interior, the transparent head building provides a clear view of the front courtyard. As in the forecourt, the trees were not illuminated here for ecological reasons. However, the highlighting of the magazine building clad in folded architectural bronze was a component of the holistic lighting design. In meticulous coordination with the involved parties and by means of nocturnal sampling, a grazing light solution was developed that cuts off the majority of the light cone at the edge of the building and creates only a gentle light presence of the bronze folded facade. For this purpose, linear recessed floor luminaires were precisely located in the front courtyard. Adjustable surface-mounted luminaires were mounted on the shell building along the sides of the treasure house.
