Features of GHE Analysis

Key features include:

  • User-friendly modeling of irregularly shaped borehole fields affected by groundwater flow
  • Instant hourly simulation of hybrid GSHP systems and sCOP evaluation
  • Automatic calculation of convective resistance with different heat transfer fluid mixtures
  • Interactive borehole heat exchanger design and calculation of effective borehole resistance
  • GHE sizing using the alternative ASHRAE method
  • Extensive verifications against published values and academic codes

Version 1.2 (March 31, 2025):

  • Simulation of fluid temperature is now 3 times faster
  • You can now show datatips on some charts
  • The groundwater flow velocity now has a wider range of applications.
  • You can now copy borehole coordinates directly from the table.
  • Addition of a few minor features and GUI improvements
  • Minor bug fixes and stability improvements

Version 1.1 (February 17, 2025):

  • The g-function evaluation is now 2.5 times faster, running in 40 ms for 100 borehole fields on most desktop computers
  • You can now enter monthly base and peak loads in addition to hourly building or ground loads
