The building's strengths?
The building’s strengths
- France’s 1st BEPOS - E4C2 industrial building
- Carbon sobriety:
750 kgCO2/m² (C2 level – 15%)
Comparative carbon analysis of local brickworks
500,000 handmade terracotta bricks and reuse of offcuts for exterior cladding
160 m3 of solid wood from French sustainably managed forests (PEFC)
Decarbonized energy < 2 kgCO2/m²/year - Energy sobriety & efficiency:
Bioclimatic optimization of the envelope (parametric design of workshops, CFD studies, etc.)
Integration of passive comfort features (natural ventilation, low-emissivity blinds, accessible inertia, etc.).
Detailed energy simulation taking into account process consumption and inputs
Geothermal heating/cooling production with BTES probes (inter-seasonal thermal storage)
Photovoltaic production > Total site electricity consumption
Heat recovery from cold rooms for DHW production
ENR&R rate > 70 - Environmental stewardship:
Gold level achieved using the Hermès Sustainable Construction guidelines
Green building site (80% of waste recycled, 95% local companies)
Air quality guaranteed by reception tests (VOCT, Formaldehydes, PM10)
40% water savings compared to standard leather goods
Positive biodiversity (native and melliferous plants, berry bushes, beehives)
Drafting of a user guide (educating people about thermal comfort and cladding)
Congratulations to Bilel Ben Brahim, Ayoub El Homaini, Anne H., Nina Mahé-Rome, and Mathilde Poirier for their participation in this project, and to Kévin Bâcle for seeing it through to the end.
