Abstract: The exploitation of shallow geothermal energy is challenging with respect to planning, dimensioning and approval procedures. All of these processes, as well as the achievable prediction accuracy, significantly depend on the data consistency. To reduce the complexity, all necessary data should be gathered in one database, serving as a tool in which the prementioned processes can be performed. This paper presents the geothermal information system GeTIS. It provides geothermal-related information that is needed by house owners, engineers and public authorities. Furthermore, it provides 3D subsurface and building performance simulations up to city district scale as well as plug-ins for the simulation tool FEFLOW. The used methods and standards are described and preliminary results of a practice-orientated dimensioning of a geothermal plant are presented.
