An innovative design of glass walls for the new administration building of the ZEG was created to contain remote controlled louvers and - at night - to be illuminated with LEDs. In a continuing effort to work on the most modern engineering level, the concrete surfaces are covered with large aluminium ceiling panels. Recessed into these aluminium panels is the selux M100 system incorporating T5 fluorescent lamps for general illumination. The i-spot track mounted spotlight, complete with DALI transformers are also used with our M100, for intelligent accent lighting.
