GHE Analysis features and specifications
GHE Analysis 3.0 covers the design of a ground-source heat pump system from the building loads to the annual operating cost. It models geocooling (also known as passive or free cooling) and domestic hot water (DHW), computes the energy cost, and offers seven chart views, including the Sankey energy-flow diagram. The table below summarises the main features of this release.
