How can one of the first HEQ buildings on an abandoned, polluted and noisy area in the Île de France be declined? The project appears as a “shield” defending itself from noise. The outer wall is encircled on two sides by a double skin glazed envelope, a genuine acoustic protection allowing to circulate in the building, to enjoy the views and natural light. The noise is visible but not heard. The spirit escapes, the landscape of roads and rails invites to travel. The composition offers a graphic and refined processing of the volumes. A system of polished white concrete boxes on the facades allows to punctuate the lines while preventing the pollution from settling. The project also turned out to be very innovative in offering optimal thermal insulation thanks to the construction of a Canadian well, the largest in France at the time. It thus provides an energy-saving response and meets the expectations of a school audience, particularly in terms of sound protection, serenity and brightness.
