Banque Populaire Auvergne Rhône Alpes will use our geothermal heating and cooling solution as part of the energy rehabilitation and modernization of its site in Corenc, France. The entire project is headed by Bouygues Bâtiment Sud-Est.
Under the French ELAN law, commercial buildings must be able to reduce their energy consumption by 40% by 2030, in order to achieve 60% savings by 2050.
The choice of Celsius Energy's shallow geothermal energy - or geoenergy - solution is in line with Banque Populaire Auvergne Rhône Alpes' ambitions to reduce its carbon footprint and be in step with environmental challenges by 2050.
Celsius Energy will implement a geothermal heating and cooling system using inclined probes in the 7,680-sq. m. administrative building of Banque Populaire Auvergne Rhône Alpes in Corenc. The complete system by Celsius Energy will include a heat exchanger with small footprint, a geothermal heat pump and a digital control device to monitor and optimize energy performance.
As part of the project, Celsius Energy will deploy its technology by drilling 12 inclined boreholes 120 meters deep, each equipped with double "U" probes - a proprietary system that exchanges calories and frigories with the subsoil. This solution will cover 88% of the building's heating needs and 94% of its cooling needs.
Celsius Energy's innovative approach lies in optimizing geothermal systems while making them accessible in urban environments, particularly for renovation. In addition to optimized design, its digital technologies enable installations to interface with building management systems. Our innovative use of inclined probes considerably reduces the footprint required for construction work. At the Corenc site, for example, the 12 inclined boreholes require a footprint equivalent to that of two parking spaces, compared with the nearly 500 m2 required (around 20 parking spaces) for vertical boreholes.
BPAURA will be undertaking other efforts as part of the energy renovation at the Corenc site. These will include the installation of 500 solar panels, relamping with LED lighting, and the implementation of a technical building management (BMS) for the regulation and management of energy systems.
The modernization work is being headed by Bouygues Bâtiment Sud-Es in a partnership with the architect Ludmer&Bouvier, the engineering consultancy Thermi-Fluides and the building environmental quality consultancy Alterea. The 16-month project is scheduled for completion at the end of 2024.
