Housing estate "Leuchte" — Geothermal Response Test
In late 2023, the foundation 'St. Katharinen- und Weißfrauenstiftung' comissioned a geothermal response test (GRT) to investigate the thermal conductivity on the building site for the construction of a new senior citizens' residential complex and two apartment blocks in Frankfurt Bergen-Enkheim.
After evaluating the GRT measurement, which was carried out using a geothermal probe at a final depth of 160 metres, the favoured energy supply for the buildings can be implemented using a brine heat pump in conjunction with a geothermal probe field. The pilot borehole required for the test will be integrated into the probe field at a later date so that no additional costs are incurred when the project is subsequently realised. By utilising geothermal energy, a significant proportion of the energy requirements of the new buildings at St. Katharinen and Weißfrauenstift can be covered in a climate-friendly manner.
PROPROJEKT is supporting the project with project management services in accordance with AHO at all project stages. The project is currently in the design planning phase (LP 3). The overall completion of the residential complex is planned for mid-2026.
