[EnergyPlus_Support] Baseline and proposed heating in EnergyPlus

This question is really about ASHRAE 90.1.  However, since we are using EnergyPlus to simulate the building, we hope that it can be answered here.

The simulated building has five stories.  The design (proposed model) only has heating (by a ground source heat pump) for the 5th floor, which is an office space.  The bottom 4 floors have no heating in the design.

According to Table G3.1 in Appendix G of ASHRAE 90.1-2007:

Where no heating system exists or no heating system has been specified, the heating system classification shall be assumed to be electric, and the system characteristics shall be identical to the system modeled in the baseline building design.

Our baseline model is ASHRAE system 8 (VAV + PFP boxes, heating provided by electric).  Does this mean that our proposed model has to add electric heating into the EnergyPlus model despite the fact that the acutal design does not have heating? 

Thanks!
