Sustainable development approach of the project owner
The materials used, which are straw and earth, provide the building with a great inertia, making it possible to fight against temperature variations which would have a disastrous effect on the quality of the wine produced. These materials also help naturally manage hygrometric variations. Existence of a well for hygrometry which is little, or even not used, due to a low water flow. Nevertheless, it is part of a very old network of wells connected by faults and natural galleries, allowing air circulation at around 12 ° C saturated with humidity. The semi-buried structure requires neither heating nor cooling system and ventilation is done naturally in particular thanks to a buried air inlet. The use of wood cladding contributes to integration into its environment.

Reasons for participating in the competition(s)
Le bois et la paille permettent de stocker du carbone, au-delà de la quasi absence d'émissions de GES lors du fonctionnement ce bâtiment. L'ouvrage semi enterré ne nécessite ni chauffage, ni système de rafraîchissement et la ventilation se fait de manière naturelle notamment grâce à une arrivée d'air enterrée.
