At depths between 10m to a few 100 m, the temperature of the ground remains undisturbed all year, at a typical value of 12 to 15°C. This geo-energy can be used for direct "free" cooling of buildings, and low consumption heating in winter thanks to a heat pump. However this local and renewable energy is insufficiently deployed in several European countries like France, mainly because owners are not aware of their underground resources. At Geosophy, we develop Physics and financial models, using data science and machine learning techniques to automatize and refine feasibility studies of geo-energy installations. We are therefore able to assess geo-energy potential of buildings, both on technical and commercial aspects, at park or building level.
