Inaugurated last January, the Simone Veil school complex in Evreux (27) is a new construction capable of accommodating almost 300 primary school pupils, divided into 15 classes.

Located in a verdant setting along the Rue du Bois des Communes, the new facility is connected to existing facilities (extracurricular reception and sports complex) and has been designed using a maximum of natural materials and the latest advances in eco-construction technology, with bio-sourced materials for the insulation and geosourced materials for the facade. As a result, the building’s low energy consumption guarantees the comfort and health of its young pupils.

The environmental approach is based on the principles of bioclimatism, combining energy performance, low carbon impact and indoor air quality. To comply with current thermal and environmental regulations, the low-energy building envelope is clad withCladding with backing structure (ventilated facade). The overall project, which was aiming for E+C- certification (a pre-RE2020 experiment), thus achieves the Passivhaus standard.

The combination of materials used is a key factor in the success of this project: the timber structure (Timber frame construction) rests on a concrete backbone. Walls and roofs were insulated with bio-sourced materials: compacted straw, encased in wooden caissons. As for the Cladding, it is geosourced: the Mineral facade is made up of over 80% mineral fillers geosourced near our production sites.

Facade cladding is in fact CAREA Ardal and Acantha tiles with the following finishes SMOOTH MATT appearance.appearance, with the choice of a warm, metallic Onyx Cuivre color.

The architect wanted to extend the copper finish to the fifth façade, so the same cladding was used for the roof overhang, following a feasibility study by the CAREA design office, which provided technical suggestions and validated the system.
