Identification

ACCENTA heating and cooling system relies on a predictive and self-learning intelligent control system, which optimizes in real time the efficiency of thermal energy production for the building according to demand.

With 27% of the French CO2 emissions, the building sector is a major contributor. Improving its carbon footprint is, therefore, a significant challenge, with a targeted effort on heating, which accounts for 75% of the emissions. This is a global issue as most developed countries display similar patterns. ACCENTA invented a low-carbon heating and cooling system that reduces up to 95% of the CO2 emissions compared to standard solutions. It relies on inter-seasonal geostorage and waste heat, from air-conditioners or low-carbon solar heat, produced during summer and stored into the ground. In winter, heat pump's yields are optimized by up to 50% using the stored heat, drastically cutting both energy consumption and CO2 emissions.

Implementation Stories

Geostorage by ACCENTA by ACCENTA
Implemented by Airbus in Toulouse (France) in 2023

Airbus has implemented the Solution for its new 36,000 m2 headquarters in Toulouse-Blagnac in 2019. Vinci Energies is currently operating the system to optimize their energy efficiency and carbon footprint over time. The geothermal collection system consists of 141 vertical probes at a depth of 205 meters. Production is ensured by three thermodynamic substations connected to the probe field by a 400-meter long tempered water loop.

Result

-77% energy consumption & -87% co2 compared to a standard solution using gas and chillers
