Measurement data of the thermal investigation of geothermally activated building systems using Thermal-Response-Test method

The dataset contains temperature and volume flow data of three thermal response tests (TRTs) carried out from August 2022 to February 2023. The TRTs were applied to a so-called gTABS, a geothermally activated building systems consisting of horizontally installed pipes placed under a building. A TRT device provided a constant heating rate and volume flow to the gTABS, resulting in a continuous increase in fluid temperature during the tests. This temperature increase can be evaluated as described here:

Each .csv file includes following header (column name [unit or format]):
date_time[yyyy-mm-dd HH:MM:SS],Temperature_in[degC],Temperature_out,Volumeflow[m3/h]

The data was logged with a constant timestep of one minute.
