Table 1 Distribution of monthly thermal load over one year from the building, along with calculated values for the BHE
From: Modeling neighborhood-scale shallow geothermal energy utilization: a case study in Berlin
Month | Relative thermal load | Absolute monthly thermal load on BHE array [kWh] | Absolute monthly thermal load on each BHE [kWh] | Temperature difference (\(T_{\text {out}} (t) - T_{\text {in}} (t)\)) on each BHE acc. to Eq. (5) [K] |
