I am modeling a building to submit to LEED certification and I have a concern regard to the baseline HVAC system and the increment of 15% applied to the Equipment Capacity.

First, regarding to the baseline HVAC system, I am using two chillers and fan coils to met the thermal load of the proposed model. Considering that my building has three floors, I choose the system 4, as presented in the picture below.

To represent this system in EnergyPlus, I set the following system in OpenStudio (Packaged Rooftop Heat Pump).

Is it the right representation of the system 4 (appendix G- Table G.3.1.1B)?

Second, Should I Set the 15 % for both models, baseline and proposed model, or only apply this coeficient for the baseline model.
