Actelion Business Center
The Business Centre is at the heart of the growing Actelion complex. Its architecture is meant to offer an inspiring working environment, its forms stand for 'innovation, openness and communication' (J.-P. Clozel). Consisting of two floors under the ground and six floors above it, this building includes workspaces for 350 people, an auditorium and a restaurant. An open steel construction provides support for cantilevered floors of different layouts, stacked atop of each other. Jutting out in various directions, all the floors meet at four points that allow for vertical communication. Although surface to volume ratio is large, the building incorporates many features aimed at sustainability - e.g., green roofs, triple glazed glass, reactive louvers, photovoltaic cells.
