The energy efficient design of this building has a passive purpose, based on the following bioclimatic principles:
- efficient insulation
- Solar gains and inertia
- roof overhang to protect summer overheating.
Reduce the project's carbon footprint: The environmental footprint remains low due to the use of bio-sourced materials:
- country wood for untreated framing (Douglas fir, chestnut),
- organic straw of the town for the insulation of walls and roof,
- cork for floor insulation and clay-based earthenware on straw walls.
