[Bldg-sim] VRF and LEED Certification

[Scott Hackel]

Jim -
Unfortunately I don't yet have experience in modeling VRF systems, but I have some info... At the moment, the EnergyPro package would be the one to use for VRF.  Both of the major VRF manufacturers do stand behind the EnergyPro algorithm, and performance curves from current VRF equipment are used in that software.  You'll likely find it more cumbersome than TRACE, but TRACE's VRF system has not really been validated to my knowledge (anyone from CDS, please clarify if I'm mistaken).

eQUEST developer's do plan to introduce VRF in a version in the near future, but I haven't heard any recent updates on the schedule for that.
