Observation-Deck
Congress-Halls
Mediatheque

The elevators with panoramic view are located in a glazed enclosure outside the building's core.
A hierarchical system with express-elevators, which stop at every 11th level at the sky-centers only, and secondary-elevators for local traffic from level to level in-between the sky-centers, enables fast vertical transportation requiring minimum floor area.
3 storeys are grouped together around atriums on the building's east- and west- sides .
By single glazed wall-elements natural ventilation and daylight are facilitated for the office-floors through the atriums.
Due to its height of 9,10 m the atrium can be used for special exhibitions, or as a greenhouse.
The access of sunrays through the atrium´s big window is easily controllable by means of vertical sliding screens, which (if printed on) can display messages by the tenant behind.
