GHE Analysis features and specifications
GHE Analysis version 3.0 covers the whole design workflow of a ground-source heat pump system, from the building loads to the annual operating cost. Its modelling capabilities include geocooling (also known as passive or free cooling), domestic hot water (DHW) simulation, an energy cost module, a full set of chart views up to the Sankey energy-flow diagram, and a deep integration between all design steps. The table below summarises the principal features available in this release.
