Design: The new building for 600 students is the result of a competition, consisting of the school building itself, a gym, and a bus stop. All companies involved in the construction process committed in writing to reduce the impact of noise and other emissions during the construction.
Wood: The pragmatic design approach included the use of wood for loadbearing purposes wherever such a solution is viable. For this reason, concrete was used for parts of the ground level. A timber frame construction was employed for the classrooms, the library, and the multipurpose hall, as well as for the schoolyard roofing. The school is the first example for the cooperation between Bois des Alpes™ and the associative initiative Bois Qualité Savoie, which was founded by members of the regional wood industry. The sawmills, as part of said initiative, obtained the wood from within 100 kilometers, and the manufacturer of the cross-laminated timber is a local company.
Energy: The building owners aimed to reduce the ecological footprint through the reduction of gray energy. For this reason and among other measures, recycled material (cotton and textile fabrics) and local wood was used for the insulation and the construction respectively.
