Performance of a Ground Source Heat Pump System in a Near-Zero Energy Home

Due to its high energy efficiency, ground source heat pump (GSHP) systems have been applied in many zero or near-zero energy buildings, which use renewable power generated on-site to offset partially, or completely, the energy consumed in the building on an annual basis. How does the GSHP system perform in these buildings? How much does it contribute to reaching the goal of zero or near-zero energy? In this article, the real performance of a near-zero energy home and its GSHP system will be presented.
