Reducing Capital Cost for Geothermal Heat Pump Systems Through Dynamic Borefield Sizing

---

Geothermal heat pump systems offer a sustainable solution for heating and cooling of
buildings, significantly contributing to climate goals by reducing greenhouse gas
emissions and achieving carbon neutrality. However, the higher initial costs associated
with the borefield pose a barrier to widespread adoption. This article explores how
dynamic borehole modeling can optimize borefield sizing, achieving up to a 35% size
reduction in the investigated cases, thereby making these systems more cost-effective.
