The Project

HERMES has built its 24th factory for leather bags and accessories in Isle d'Espagnac (16). The cutting, stitching, and assembly workshops will eventually employ 300 people by 2028.

HERMES aims to phase out the use of fossil fuels at its industrial sites by 2030, unless there are demonstrated technical impediments. The company is also deeply committed to preserve biodiversity, and to construct its facilities to meet the highest environmental standards.

These requirements led HERMES to choose geothermal energy to provide heating and cooling for the Isle d'Espagnac manufacturing facility. The borehole field (probes) was drilled within the construction footprint of the building to minimize the impact on the land.

Our Role
