The Challenge
In December 2003 Barbara Hediger, creates an inovating lighting and illumination plan for the Centre International Rogier soon to become the Dexia Tower located in downtown Brussels.
Barbara's Challenge ? Light up and illuminate a 38 stories building with a 90 % glass façade and roof. Glass does not reflect light it absorbs it.... ,on the other haud it is transparent. It is from this basic premise that the concept originated from:
« design an exterior façade light scheme by the interior »
The Project
Barbara Hediger's illumination and lights project promotes the specific architectural qualities of the building.
The architectural artistic values do not suffer from the lighting project instead it is integrated to provide the building with a nightlife volume near that of it's daylight .
The technological answer to these criterias was LED a remarkable light source.
LED provides a superior light intensity, yields up to 40% energy savings and offers an extraordinary palette of colors.
No less than 220,000 LED's allowed the creation of an exceptional dynamic effect never attained to date, thus establishing a precedent in architectural lighting and illumination.
The Outcome
A dynamic lighting system controllable and managed by one software program, one PC and two monitors. A building whose's image varies in fonction of colors and the story depth provided by the window shade angles.
