Apologies for cross posting.

I am modeling the baseline according to 90.1-2010 Section 11. The proposed design uses heat recovery chillers with boilers to pick up what the heating loads HR chiller isn't able to meet. In this case, would the heating classification be Heat Pump? The HR chillers meet the majority of heating loads. 11.3.2.(j).(2) indicates that the systems served by the secondary heating source type are to be modeled the same in the baseline. In my case I can't really separate the systems as all systems use heating provided by both the HR Chillers and the boiler plant.

Any idea how the baseline plant and systems should be modelled? Water source heat pumps (System 6) may be appropriate but I would have to add a DOAS.

At the moment, the baseline model has System 2 (VAV with boiler and chiller) but this leads to much lower electricity consumption in the baseline. The purpose of the modeling is for an incentive based on electricity savings - either kWh or kW which ever gives the best incentive. I do have peak kW savings but it would be much better if the baseline had electric heating of some kind along with the gas heating.

Any insights appreciated.
