Value propositions

Turning an investment into a controlled operating expense

Securing subsidies: Heat Fund & Energy Savings Certificates

The Heat Fund and Energy Savings Certificates (CEE) are built in from the project design stage. On real projects, the initial investment has been reduced by up to 80% before any additional financing arrangement.

Landlord CAPEX + tenant rent supplement

The owner bears the investment and agrees a rent supplement with the tenant, indexed to the costs avoided. This model provides visibility on profitability and sustains the landlord-tenant relationship over the term of the lease.

Third-party financing: zero owner CAPEX

A third-party investor provides all the financing. The client pays an annual charge lower than or equal to its current energy spending: price stability, integration of renewable energy, and a fair split of investment and costs.

Third-party operator with an Energy Performance Contract

The installer finances, operates and contracts the charges directly with the occupants. Responsibility for performance is clearly identified and borne by whoever designed and built the installation, with no break between design and operation.

Testimonial

“The close collaboration between the owners’ council, Accenta and Foncia is at the heart of this project’s success. Thanks to this collaborative work, all residents can now benefit from a significant and lasting 76% reduction in their energy bill.”

  • LOW-CARBON HEATING AND COOLING

    Gex co-ownership

    Shallow borehole geothermal energy used as a natural thermal storage source for heating and domestic hot water. Financed through an energy performance contract, energy savings certificates (CEE) and the Heat Fund, with no upfront cash outlay for the co-ownership.

  • AI-DRIVEN CONTROL AND OPTIMISATION

    Emeis – 3 healthcare facilities

    17,000 m² of clinics and care homes (Andilly, Paris 16, Boulogne-Billancourt) managed on a single platform. Unified BMS, dynamic AI, air-source heat pump — all financed by the savings generated through an Energy Performance Contract (EPC), IPMVP protocol, without committing any of Emeis’s CAPEX.

  • ENERGY STORAGE AND FLEXIBILITY

    Bessières greenhouses

    Recovery of waste heat from the Bessières energy-from-waste plant (196,000 t/year of waste) to supply renewable cooling to the Serres de Bessières greenhouses (10 ha, 6,000 t of tomatoes/year). LH2C (Low Heat to Cold) technology: charging and discharging on the same site. A local circular economy between a waste heat producer and an agricultural cooling consumer. Financing: Water Horizon + ADEME.
