What it really is

Shallow geothermal for logistics warehouses and commercial buildings

Shallow geothermal uses the stable heat of the ground (between 10 and 14°C in France) as an energy source for heat pumps. It covers heating and cooling of commercial and logistics buildings.

There are two main types: vertical borehole probes (deep boreholes 80 to 200 m) and aquifer systems (groundwater pumping). Each has its specific constraints. PLACEHOLDER

Geothermal is not always the right solution. My role is to tell you objectively whether it is — or whether it is not.

What I deliver
  • Analysis of the site's geothermal potential (BRGM data)
  • Feasibility criteria verification
  • Geothermal / air-source comparison for your project
  • Savings estimate and mobilisable EEC
  • Argued recommendation: go / no-go / hybrid

Frequently asked questions

Geothermal for warehouses and commercial buildings: what I am often asked

For commercial and logistics buildings, the applicable schemes are: BAT-TH-162 (water/water or ground/water heat pump, borehole field or aquifer), BAT-TH-163 (air/water heat pump in commercial buildings) and BAT-TH-164 (ventilation system with heat recovery). BAT-TH-162, with the commercial heating bonus (×5), generates the highest EEC volumes — sufficient to cover the entire geothermal CAPEX on large warehouses (≥ 10,000 m²). I coordinate the preparation of the EEC file from the design phase to guarantee administrative compliance.
Une étude de sol préliminaire (test de réponse thermique - TRT) est nécessaire pour confirmer la compatibilité et dimensionner les forages. Elle coûte entre 3 000 et 8 000 euros. My role is to validate upfront whether this study is worth commissioning, by analysing available geological data (BRGM, neighbouring boreholes) and your project constraints.
Not systematically. Warehouses have highly variable thermal needs and specific ground constraints (loading bays, circulation areas). Aquifer geothermal may be relevant for the main cells; borehole geothermal is often ruled out by insufficient available land. Each case is unique — I analyse it project by project.
Sous-dimensionnement des forages (par réduction de coût), sur-promesse des installateurs sur les COP réels, non-conformité du dossier CEE entraînant un rejet administratif, incompatibilité avec le régime d'exploitation, et oubli des coûts de maintenance à long terme. My analysis systematically integrates these risks from the orientation phase.
Yes, hybrid systems are often the optimal solution: geothermal covers the base load with a high and stable COP, air-source takes over for peaks and ensures continuity during maintenance. This hybridisation also limits borehole capacity — and thus CAPEX — while preserving eligibility for geothermal EEC (coverage factor R ≥ 40%).
Geothermal EEC rely on scheme BAT-TH-162, with a commercial heating bonus of ×5. On a large-footprint asset, this mechanism can cover the entire geothermal CAPEX. The downside: non-compliant sizing — insufficient R factor, underestimated COP, incomplete file — can lead to permanent administrative rejection. Technical rigour from the design stage is therefore essential. I manage this coordination between the HVAC engineering firm and the EEC specialist.
Regulatory context

Geothermal, warehouses and the Tertiary Decree: the right time to act

Logistics assets over 1,000 m² are subject to the tertiary eco-energy decree : réduction de consommation de 40 % en 2030, 50 % en 2040, 60 % en 2050. Shallow geothermal — coupled with a water/water heat pump — achieves these targets in a single operation while benefiting from near-full EEC financing via la fiche BAT-TH-162.

The commercial heating bonus (×5 on EEC volume) is conditional on replacing a gas or oil boiler with a geothermal heat pump presenting a coverage factor R ≥ 40% and a certified compliant COP. On a warehouse of 20,000 m² or more, the net cost after EEC valorisation is frequently zero — this is the distinguishing feature of this technology compared to air-source.

My positioning as an independent owner's rep - with no connection to installers or EEC obligated parties - ensures that the selected sizing and the regulatory file are optimised for your benefit, not to maximise an intermediary's commission.
