Sustainable development approach of the project owner
The main objective is twofold:
- aim for energy excellence, with the BEPOS Effinergie level, and make the building an exemplary case of compensation for energy consumption through local production
- incorporate a maximum of local materials and biobased, through the facade and wood frame, with insulation by straw bales (choice of companies and local suppliers)
Architectural description
This building presents a mixed structure:
- The superstructure of the building is of the post / concrete beam type, with slab and intermediate floors also provided in concrete, so as to provide the necessary thermal inertia for the building
- All facades, as well as the roof are made of wood / straw construction.

Reasons for participating in the competition(s)
Le bâtiment est en construction ossature bois, et l’intégralité des façades extérieures est isolé par des bottes de paille (provenant du département). Ce choix provient d’une volonté de construction en utilisant les ressources locales et duplicables, faiblement émettrices de gaz à effet de serre.
