Subproject 4.1

Extension of consistent modelling

Lead Management Subproject Leader Participating Partners
The method of analytical and consistent modelling of shallow geothermal source systems [Van de Ven et al, 2018] developed in the predecessor project QEWS II, which is successfully applied to various systems, is completed in this project. The overarching goal is to enable a neutral, manufacturer-independent comparison of different source systems and source system combinations for planning and design, in which the methodological basis of the models is basically the same for all system types. In this way, all major closed-loop shallow geothermal source systems, including their relevant effects, can be calculated and compared in a planning tool on a methodologically uniform basis.

• Extension of the g-functions of borehole heat exchangers with groundwater advection
• Development of a consistent model for geothermally activated components
• Optimisation of modelling accuracy and practicability due to the cooperation of HBC-IGE and H.S.W. GmbH
• Validation of the models with real and scientifically reliable measurement data
