Potential suitability of soils for geothermal collectors - EWK: Suitability of the floor - OGC API Features
Description
This application provides developers, planners and contractors with information on the potential suitability of the near-surface subsoil (soil depths up to 2 m) for the production of thermal energy. Furthermore, thermal conductivity can be called up, which plays an important role in the dimensioning of geothermal collectors. Geothermal heat collectors often represent a sensible and more cost-effective alternative to geothermal heat probes if there is sufficient space available. In addition, they can be an alternative to geothermal probes in critical areas of water management (drinking water protection areas, healing spring protection areas, mineral water protection areas), which are often not subject to approval. The basis for the theme maps are the soil data of the digital soil overview map on a scale of 1: 200,000 (BÜK 200). The BÜK 200 is part of the soil specialist information system of the LGB. It provides information on the structure and composition of the shallow subsurface to a maximum depth of two metres. It should be noted that the maps are for orientation only. The site suitability of soils for the production of geothermal energy is particularly good on areas with high heat extraction pipes. The water balance is of paramount importance here. Particularly well suited are deep soils with good moisture penetration and/or low groundwater levels. Slightly suitable are stony, shallow soils, in which the pending rock occurs above 1.2 m below the surface of the terrain. Here it is necessary to calculate with low heat extraction capacities and the geothermal collectors may not be installed deep enough. Deep soils without watering are generally suitable. The site conditions can be improved if necessary by the infiltration of rainwater.
