[Bldg-sim] Mixed fuel baseline for LEED

It would be easiest if you used option 2 per the USGBC district energy modeling guidelines.  Then the baseline doesn't change.  I would then choose heating source based on the predominant system, which I would assume is the VRF.

We have a building that uses VRF systems for Space cooling/heating. However the Outdoor air is conditioned using Hot/Chilled water from the campus loop. This poses a challenge in selecting the baseline.

If anybody and experienced this situation could you please hint on your approach.
