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.
