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)
Wood and straw allow for carbon storage, beyond the near absence of GHG emissions during the operation of this building. The semi-buried structure requires neither heating nor cooling system and ventilation is done in a natural way notably thanks to a buried air inlet.
