Reine Energie Reinertrag

Non-certified passive dwelling-house pilot project

The aim of the project is to supply the lowered heating-cooling requirements totally by renewable energy. The geothermal heat pump and the solar collector system are already installed in 2011.

4x100 m BHEs were installed to the dwelling-house in 2011 and we carried two Thermal Response Tests out. The pipes were single U with 40mm diameter.

At first we measured the undisturbed in situ temperature in the BHE after drilling and after that the TRT was carried out. The inlet, outlet temperature, mass flow and air temperature were recorded. The result of evaluation was the thermal conductivity value.
