Revision history [back]

You're on the right track, but you should use a single ground source loop where the ground source heat exchanger is on the supply side, and then both the AHU cooling and heating coils are on the demand side (see below).

You will just need to be sure to apply the proper setpoint manager objects to achieve the desired outlet temperature (read more here). I'll point out here that using the ground source heat exchanger objects requires lots of inputs for the bore holes and other data that is best obtained from a ground source system design tool like GLHEPro. Unless you already have this info, you can create a preliminary system using district heating and cooling objects on the supply side (see below) to generate ground source condenser loop capacities, then use that info to size the ground source heat exchangers. For more info, check out this tutorial and this question.
