Geothermal energy to heat and cool your buildings
A geothermal solution for heating and cooling buildings, Celsius provides occupants with low-carbon thermal comfort all year round.
The Celsius system is mainly composed of three elements:
- A closed star-shaped geothermal exchanger, equipped with double-U probes, typically 200 meters deep, in which a heat transfer fluid circulates. This innovative structure drastically reduces the surface footprint while optimizing the thermal exploitation of the underground. The solution is therefore suitable for both new buildings and renovation, including in urban areas.
- A heat pump allows calories to be exchanged with the underground , to supply them to the building in winter and extract them in summer. The simultaneous supply of hot and cold is also possible.
- An advanced digital control minimizes electricity consumption by optimizing the operation of the subsurface and the use of heat pumps coupled to the building in real time. Digital control also guarantees system performance and reduces the maintenance of connected heat pumps.
Cooling buildings in summer recharges the under-ground through heat extracted from the building. Generating hot and cold from the same system reduces the number of wells required and therefore the overall investment cost (inter-seasonal thermal storage). Cooling can be carried out in passive mode (free-cooling or geocooling).
An ecological solution
Did you know that 25% of CO₂ emissions were linked to buildings?
Compliance with the Paris Agreements requires radically rethinking the heating of our existing buildings and innovating for new constructions. Celsius can heat and cool buildings by eliminating 90% of CO₂ emissions per kWh generated compared to the benchmark solution in France (gas and chillers).
The Life Cycle Assessment of the Celsius solution carried out by a specialist firm shows that the environmental impact of the Celsius solution is compensated in 10 months compared to the reference heating solution, gas. After 20 years, Celsius’ global warming potential is ten times lower than that of gas heating.
Celsius favors obtaining the labels expressed by the contracting authority, with a projection of reduced primary energy consumption through the use of electric heat pumps, displaying an excellent coefficient of performance (COP).
Celsius cools your buildings without releasing hot air outside the building, eliminating the risk of heat islands during heat waves.
An economical and rewarding solution
Celsius makes your buildings independent from the variations of gas and oil prices. The Celsius solution with its digital control reduces operating costs, generating savings on the management of your building.
Even if the initial investment may be higher, the reduction in operating costs allows a payback time typically between 5 and 10 years compared to the reference solution (gas and chiller), covering from 80 to 100% of the thermal needs of buildings through geothermal energy, including domestic hot water.
The value of your building increases thanks to Celsius, which is part of a real strategy of low carbon sustainable building and innovative eco-district.
A solution adapted to your building
The Celsius system does not require the installation of external equipment, eliminating visual and noise pollution.
The small footprint after completion and during construction makes it suitable for most buildings, including in dense urban areas.
In the case of a new construction, the impact on the planning of a site and on delivery times is minimal thanks again to the small footprint required during the construction of the underground structure, which therefore hardly interferes with the rest of the construction.
A constant and resilient resource
Celsius is a sustainable, local and permanent renewable energy solution. It does not share the intermittences of other renewable energies (solar, wind): the energy of the Earth is there all year, night and day. 70% of the energy your building needs is already under your feet. Celsius allows you to use and manage it intelligently.

Celsius offers to study the Celsius feasibility for your buildings and provide an estimate of the various technical, financial and environmental parameters.
