Value proposition

Decarbonising thermal production, from design to operation

Assessment & Tailored Design

Before any commitment, we carry out a dynamic thermal simulation of the building and identify the optimal technical and economic solution: CAPEX, OPEX and available subsidies included.

Hybrid Thermal Systems

Hybridisation (geothermal energy, inter-seasonal geo-storage, air-source energy, solar thermal) achieves what a single-technology solution cannot: between -40% and -95% CO₂ emissions.

Prefabricated Modular Boiler Plant

Factory-built, installed in less than 10 days, with no interruption to operations. It is the answer to the operational constraints of renovating occupied buildings.

Testimonial

“This project embodies our commitment to bringing this institution of excellence a new technology to test an unprecedented and sustainable energy mix, combining geothermal energy, solar energy and smart control. We are proud to support École Polytechnique on an exemplary path towards carbon neutrality.”

  • LOW-CARBON HEATING AND COOLING

    École Polytechnique in Palaiseau

    The engineering school chose borehole geothermal energy to provide heating and hot water to its 4-building campus residence. The gas boiler was completely replaced, installed without disrupting campus life, cutting the energy bill by 60%.

  • LOW-CARBON HEATING AND COOLING

    Icade Porte de Paris

    The Icade group, one of France’s leading commercial property companies, planned to reduce energy consumption and improve the carbon footprint of its Parc des Portes de Paris.

     

  • LOW-CARBON HEATING AND COOLING

    Société de la Tour Eiffel – SYRAH

    Société de la Tour Eiffel wanted to equip its new Urban Logistics Hub in Bobigny with a more efficient heating solution aligned with its ambition of carbon neutrality by 2050.
