M&V for C&S buildings of varying occupany when complete

I have another question related to my last one regarding M&V and the energy model. In response to my last question, Marcus clarified that the energy model for a C&S building needs to be based on a fully occupied building, regardless of occupancy at the time of initial completion. He also mentioned that doing the IPMVP M&V would be difficult for my scenario which is initially an unoccupied building. So am I correct to assume that for EAc5.1, options 1 and 2 which are based on the IPMVP are intended only for C&S buildings where all the tenant spaces will be built-out at the time of completion? Or, would at least knowing the number of tenants and their location in the building be a situation appropriate for options 1 or 2? I am wondering because there is another potential project that is similar to the one I was originally asking about, but for this one the tenant spaces are at least delineated and one will be built-out at the time of C&S completion. Would EAc5.1 options 1 and 2 be appropriate for this building?
