Sabrina Corneloup, Mouratoglou Hotel & Resort
“The installation of Accenta’s geothermal energy took place in two phases, over the winter period, so as not to disrupt our business. In terms of performance, we reduced our energy consumption by 75% and our CO₂ emissions by 91% compared to a gas/air-source heat pump solution.”

Do you have any questions?
-
Can shallow geothermal energy be installed anywhere?
Shallow geothermal energy, up to 200 meters, is feasible on approximately 98% of metropolitan France. Accenta's technology, based on probes, does not require the presence of groundwater. For a renovation, a simple piece of land near the building, such as a parking lot, a courtyard or a green space, is sufficient for the installation. This space is only used during the work and can then be used again. In the case of a new construction, the building can be built above the previously installed probe field. For each project, we carry out a preliminary analysis of the site to guarantee its feasibility.
