The department of Isère is responsible for the construction, maintenance and equipment of the 97 public colleges of Isère. As part of its air-climate-energy strategy (SACE), the Department set itself the objective “to improve the energy performance and indoor air quality of buildings.” Opened in 1980, the Pont Bishop’s College has never been heavily rehabilitated. The operation consists of a complete restructuring of this 4 352 m² college, including the improvement of functionality, accessibility standards and asbestos treatment.
