Energy-intensive building
This project concerns the construction of a wine cellar intended to raise and transform organic wine. The use of biobased materials here is fully consistent with the directions taken by producers to focus on organic wine production. 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 wines produced. These materials also help naturally manage hygrometric variations. The use of wood cladding contributes to integration into its environment. The semi-underground structure does not require heating or cooling and ventilation is done naturally, in particular thanks to a buried air inlet.

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.

Architectural description

Vertical walls:
Envelope:
  • Timber frame wall with distributed straw insulation.
  • Solid wood cladding (Douglas)
Low floor:
  • Uninsulated cement screed to keep the soil temperature
Roof:
  • Steel tank cover
  • Insulated ceiling in blown cellulose wadding (40cm thick),
  • OSB panel
  • Timber joists.

Energy consumption

  • RT 2012

Systems

    • No heating system
    • No domestic hot water system
    • No cooling system
    • Natural ventilation
    • No renewable energy systems

Urban environment

  • 370,00 %
  • The project is based on an existing structure which is a place of vinification, mechanically tempered with air conditioning. It will initially be reused as such. Then depending on the quality of the wines and the time spent in the new cellar, it will serve as a storage place.

Construction and exploitation costs

  • 250 000

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.
