An introduction of new features for conventional and hybrid GSHP simulations in eQUEST 3.7

•Three new enhancements, newly implemented into eQUEST 3.7 were presented.•The capabilities of each new feature were outlined and briefly discussed.•The new wizard features were introduced to show how to build the models through the wizard interfaces.•The comparative study was conducted to analyze the performance of conventional, undersized and hybrid GSHP systems.

Three new enhancements, newly implemented into eQUEST 3.7 are presented here. These enhancements include: (1) simulation of ground coupled water-to-water heat pump systems; (2) improved multi-year simulations for conventional and hybrid ground source heat pump (GSHP) systems; (3) model of hybrid GSHP (HGSHP) system configurations. The capabilities of each new feature are outlined and some details of the implementation or simulation techniques of each feature area are briefly discussed. Also, the new wizard features are introduced to show how to build the models through the wizard interfaces.
