Hi, Currently I am using TRNSYS for plant loop modeling, but verifying E+ capabilities too. One of the types used there is Type257a for ground heat storage, a modification on Type 557 (ground heat exchanger) to be used with simultaneous charging and discharging using four pipe boreholes with two independent counter-current circuits, developed by S. Chapuis and M. Bernier on their work " SEASONAL STORAGE OF SOLAR ENERGY IN BOREHOLE HEAT EXCHANGERS". I know EnergyPlus has the GroundholeHeatExchanger:Vertical component, but I would know if is possible to model ground heat storage as well. Any input is appreciated. Thanks

Edit: added a diagram
