Mean thermal conductivity of the substrate for the depth range 0-50m
Description
For the preparation of the potential map, the strata inventories of a total of 28742 holes were used. The above-mentioned thermal conductivity values for the water-saturated and dry or partially-saturated zone were assigned to the individual layers, taking into account the groundwater level. Using computational methods, the effective thermal conductivity values for the depth sections 0m - 50m and 0m - 100m were weighted and interpolated between the holes. The thermal conductivity is therefore displayed on two maps. The values of the thermal conductivity used were conservatively applied in order to avoid the risk of under-dimensioning of geothermal probes. Additional effects, e.g. from groundwater flow, were not taken into account. Therefore, the thermal conductivity values derived from geothermal response tests may be higher.
