The Jacqueline Auriol Training Center is a teaching building bringing together training in mechanical engineering from post-baccalaureate to bac +5 multi-supervision including a school factory, teaching rooms, lecture halls, laboratories, offices, a university restaurant upstairs and parking on the roof… All of which must communicate a unity: a challenge met for this multifunctional construction, whose facades are covered with tailor-made Ressac^® in a 500 mm grid in Touch gloss stainless steel, ST500 in Kristal and ST500 double-sided post-lacquered in RAL 9006 equivalent perforated, through which the brightness from inside the building remains preserved.
