Geothermal energy, an ally in environmental transition
Silent, invisible, yet powerful: geothermal energy draws precious heat from the bowels of the Earth. For thousands of years, humanity has been harnessing this natural resource — from the thermal baths of antiquity to today's buildings. In the face of climate challenges and the need to diversify energy sources, geothermal energy offers promising prospects.

A tertiary building in Brussels opts for geothermal energy
Developed by Immobel, Commerce 46 is a 12-storey office complex with three underground levels and total floor area of 14,200 sq. metres. Situated in the European Quarter of Brussels, the building has been occupied by European Commission services since June 2024. To supply its energy needs, it uses geothermal energy with 64 boreholes, each 93 meters deep, operated in a closed-loop system with heat pumps. Cegelec HVAC Commercial South (VINCI Energies Building Solutions) has been entrusted with the HVAC installations and energy monitoring for this vast office block.
In Portugal, a new energy source for a luxury real estate development
In Portugal, Sotécnica (VINCI Energies Building Solutions), has developed real expertise in the use of geothermal energy. Its latest achievement in this area is Ombria Resort, a luxury housing project in the Algarve region of southern Portugal.
Tiago Mendes , Commercial Manager at Sotécnica, explains: “Drawing on our considerable expertise in mechanical engineering, we successfully installed advanced HVAC systems, a building management system, comprehensive plumbing and sanitation solutions, plus the fire protection and gas networks.”
Geothermal energy comes to the Parc de Bagatelle, Paris
