Energy-intensive building

Construction of a new building for the primary school of Saint -Paul-de-Loubressac, near the existing school. This extension hosts 2 classrooms, 1 office for the teachers, bathrooms and a covered courtyard.

The operation won the 2011 call for project "Efficient building of environmental quality" launched by ADEME (French energy agency) and the Région Midi-Pyrénées.

Sustainable development approach of the project owner

The extension was chosen over the construction of a brand new building which would have been located 1km away from the center. It participates in the revitalization of the town center after the building of the renovation of the Town Hall and the post office. The architect Boris Burzio's project won the 2011 call for project "Efficient Building of Environmental Quality" launched by the ADEME and the Region Midi-Pyrenees.
It was led by the desire to limit the environmental impact of the building and to provide comfortable and healthy classrooms.

Architectural description

The new building is only one level high, with a parallelepipedic shape. It relies on a constructive system made of holders boxes filled with straw for the walls and roof, pre-assembled in the workshop.
The company behind this technique is the only one not located in the Lot area (business Filiere Bois 41 - Cyril Natali), however they chose to work with a local carpentry company, which hence had the opportunity to be trained to this original construction technique in France. All other companies working are from the Lot area or neighboring departments.

Building users opinion

Teachers and children are very happy with their new school.
