Dans le cadre de la géothermie, on considère en général la capacité thermique volumique (C), mesurée ici en [MJ/(m3.K)].Il s'agit d'une propriété importante du sous-sol concernant le dimensionnement des champs de sondes, en vue de la mise en place d'un stockage saisonnier de chaleur. La présente représentation cartographique permet de visualiser les variations de la capacité calorifique moyenne sur les cinquante premiers mètres de sol (ou pour des sondes de 50m de profondeur).\n \nCes indications ont un caractère général et sont insuffisantes au stade d'un projet d'exécution. Elles ne sauraient en aucun cas remplacer la nécessité d'études géotechniques, le cas échéant.\n\nDe plus, ces données sont à replacer dans un contexte global de planification multi-usages du sous-sol. Ainsi pour tout projet lié au sous-sol, il conviendra de prendre en compte de nombreuses thématiques complémentaires telles que :\n \n- la protection des nappes phréatiques (eau potable)\n- l'utilisation de l'espace (ouvrages, infrastructures et réseaux divers...)\n- la possibilité d'extraction de matériaux.\n- le potentiel géothermique.\n \nRapports sur la géothermie genevoise:
