I am trying to utilize the DOE Commercial Prototype Midrise and Highrise Buildings with a Heat Pump in EnergyPlus. Would the best way to go about this be to utilize the Example File for HeatPumpAuto in the EnergyPlus HVAC examples? I'm getting confused when editing the existing DOE Prototype idf, as the drop down does not provide the same options as in the HeatPumpAuto.idf in the example file.

Any guidance on this would be greatly appreciated! I attempted to use OpenStudio's built in measures for Create DOE Prototype Building + the GSHPwithDOAS but it didn't seem to be working for Highrise buildings.

The High-Rise Apartment prototype model already utilizes water-source heat pumps, so I believe you just want to add a ground heat exchanger to the source water plant loop (Single Water Plant Loop). You may also want to remove the existing boiler and fluid cooler from the Plant Supply Side Branches if you want the ground to provide all source water heating/cooling, or you could keep the existing equipment to provide supplemental capacity. Implementing GSHP on the mid-rise apartment model is more involved because the prototype does not already contain a plant loop or utilize water-source HP coils, so you would need to rebuild the entire HVAC system. I haven't used the OS measures you referenced so I don't know why those aren't working.
