The Building
Wine hangar « Le Corbet », Caves du Château d’Auvernier
The new « Le Corbet » wine hangar of the Caves du Château d’Auvernier (NE) was completed in June 2018. The owner opted for a terracotta coloured PV installation due to strict construction requirements, as the building is located in a protected area. Indeed the new wine hangar is situated in an exceptional location at the foot of the Château d’Auvernier being surrounded by Neuchâtel vineyards. The challenge of this project was to integrate this building into the existing environment by respecting the constraints related to heritage conservation, while offering an efficient and aesthetically effective solution.
The Solution
What is the Solution?
Due to strict construction requirements, as the building is located in a protected area, a terracotta coloured PV installation was the only suitable solution.
Why Does it work?
Integration of this building into the existing environment by respecting the constraints related to heritage conservation, while offering an efficient and aesthetically effective solution.
PROS
- Adaptable to site requirements (colour, texture, shape)
- Preservation of the appearance of the conservation area while producing energy in the new building.
CONS
- Lower energy performance than standard modules.
- Higher costs than a standard solution.
- Lengthy procedures to obtain all necessary authorizations.
