The amount of technically exploitable shallow geothermal energy was quantified.
- class="label">•
Therefore, a comprehensive numerical borehole heat exchanger model was employed.
- class="label">•
The concept of equivalent temperature drop is introduced.
- class="label">•
For one BHE, an equivalent temperature drop of 1.8–2.8 °C over 30 years is realistic
- class="label">•
The average extractable energy amount evaluates to be 3.5–5.4 kW h m−2 a−1.
