| Abstract | With the structural change in parts of Germany abandoned industrial and mining sites became available for a new utilization. In many cases the activation of these brown fields as residential development areas represents a favorable field for geothermal energy supply. On the one hand these areas are sufficient large for the classification of independent planning areas and furthermore the energy supply of these areas is often not adequately available. Currently in Germany Geothermal is mostly used for single building supply with ground heat exchanger and heat pumps. The plant design is made, depending on the energy demand of the buildings, by tables or via simulation. In larger development areas with many decentralized geothermal heat generators the transient and controltechnique influences of the buildings and the lowtemperature heat supply nets must be considered. The large scale integrated usage of geothermal energy for urban districts is in an early stage of development. Linked to this situation a number of feasibility studies were carried out by the GeothermalCenter in Bochum. In this paper an overview of a selected planning area with the geological conditions, the accomplished geothermal simulations and the plant concept will be presented. |
