Question-and-Answer Resource for the Building Energy Modeling Community

Kent, the ground source heat pump was one of the tricker HVAC AEDG measures to develop. We do not attempt to size the field loop. We use a schedule stepping manager by district cooling and district heating objects to control the float. The idea here is to give a good sense of what the potential benefit of a ground source heat pump is. As the design develops information will be needed about soil properties and the loop configuration. For reference attached is a screenshot of the heat pump plant loop. Also as noted in the measure modeler description, the energy use associated with the district heating and cooling isn't currently removed from the simulation results.
Since the AEDG measures have been published we have also published a series of measures and a tutorial showing how to use GLHEPro in conjunction with OpenStudio. Here are links to the measures and tutorial.
