Against a backdrop of high energy price volatility and in light of the requirements of the Tertiary Sector Decree, geothermal energy has emerged as the most effective solution for decarbonization. By harnessing the stable heat from the ground, it meets heating, cooling, and industrial process needs with unmatched efficiency.
The resource comes directly from the ground, so the only electricity used is to power the heat pump.
Unlike fossil fuels, geothermal energy is not subject to fluctuations in global markets.
A building equipped with geothermal energy has an excellent energy performance rating (DPE/EEL), which is a major asset for the green value of your properties.


Geothermal energy ensures that the goals of the 2030, 2040, and 2050 Tertiary Sector Decree will be met.

Our solutions improve the Cep, Cep NR, and IC energy metrics and radically transform the Degree-Hour metric related to summer comfort. Compliance with the RE 2020 is greatly facilitated by the integration of geothermal energy, in line with current thresholds as well as those for 2028 and 2031.

Starting in 2026, parking facilities larger than 1,500 m² will be required to generate renewable energy. Geothermal energy is an attractive alternative to solar panels for sites with heating and/or cooling needs.
In addition to heating, geothermal energy can be used to cool buildings. This solution meets the growing need for cooling while consuming very little energy, ensuring optimal comfort during the summer months without the carbon footprint and operating costs associated with air-source air conditioning.
Geothermaq assists businesses and local governments in implementing shallow geothermal solutions (groundwater or boreholes) tailored to large-scale projects.

Direct use of groundwater for maximum thermal efficiency.

A solution that can be implemented even without a groundwater table, ideal for sites where heating and cooling demands are relatively balanced.
We are your technical partner throughout the entire value chain:
A technical and economic analysis of the feasibility of geothermal energy for your project, including an exploratory well if necessary (geothermal probe or groundwater).
Optimized sizing to meet the specific needs of your processes or buildings.
Handling of regulatory matters (Mining Code, environmental issues).
Support for the project owner in the form of project management assistance (AMO) or project management services (MOE) for the execution of drilling operations.
Third-party financing for project owners who wish to purchase their energy without having to bear the investment costs.
Specialized maintenance to ensure long-term performance.
With our RGE OPQIBI 10.07 certification (Geothermal Resources), we put our recognized expertise to work for your projects. We also assist you with financial engineering, particularly in securing grants from ADEME’s Heat Fund, which can cover up to 70% of your feasibility studies and exploratory wells, as well as a significant portion of your construction costs.
The payback period for a geothermal system varies widely, ranging from one to fifteen years.
It will be shorter:
Geothermal energy is used in both new construction and renovation projects.
Under certain conditions, replacing a fossil-fuel heating system may qualify for substantial CEE incentives!
However, it is important to be mindful of the following points:
