I design a small samll house, using OpenStudio 1.7.2, with a ground source heat pump (GSHP) for space heating, cooling, and hot water use. But I've got a serious trouble in modeling HVAC. Overall scheme is like this:

(1) the main system is GSHP (2) space conditioning is supplied by underfloor radiant heating and cooled air from a terminal unit mounted on the ceiling. That is, water heated by GSHP circulates underfloor tubes, and chilled water coil exchanges heat with outdoor air to cool the air during summer.

I think water-to-water GSHP is desirable for heating, and water-to-air for cooling. However, I have no idea of how to combine those water-based loop and air loop to support for a single thermal zone. Please let me know if you possibly know how to construct GSHP with radiant floor heating without implementing "district heating or cooling" plant object.
