C&S Building with no HVAC upon initial completion

This question is related to both EAp2 and EAc5.1. I am working on the energy model for a building that will not be occupied at the time of completion and the C&S HVAC will only consist of a few unit heaters to maintain 55 Deg F during the heating season. The only part of the energy model that will be based on the actual design will be the envelope, unit heaters and outdoor lights. My question is: should the building be modeled as a hollow unoccupied building that just needs to maintain a minimum of 55 Deg F, or should it be modeled as an occupied building using the default values from Appendix G? If it should be modeled as an occupied building using default values, the measurement and verification comparison won’t be apples-to-apples since the actual energy use will be just the unit heaters in the winter and outdoor lights. Or, can we achieve M&V simply by complying with MPR 6 and provide the utility and water data in the Energy Star account? Would greatly appreciate input anyone may have.
