The EDF learning center is located at the Saclay plateau in southern Paris. It is intended to welcome some of the 160,000 employees of the electricity generating utility for a stay of one to five days as part of their continuing in house on the job learning. This retreat on the Saclay plateau, sometimes far from an employee's usual place of work, is an opportunity for staff to learn and train, but also to meet, exchange and re-energize themselves in order to consolidate a common culture. On top of the spaces reserved for learning courses there are reception areas, social life gathering spaces, relaxing lounges and even bedrooms: a variety of programs that together contribute to the exceptional chronology of an a-typical 24 hours per day operation. The idea of an American style campus is reinterpreted here vertically in this unitary building that is bringing people together in multi-functional spaces.
