90.1 compliance mandatory? Planned use of empty space?

Sorry for a couple of elementary questions, but my searches haven't been successful. 1. Is 90.1 compliance required, or only the mandatory provisions? 2. I have three floors that are empty, but planned future use is known, which will be identical to the floors above them. This future use will be designed, built, and occupied fairly soon after occupancy (maybe a year or two). I think it best to model these floors as copies of the known future layout and systems. It's sort of a gray area to me, though. Will that be OK? Thanks! Dave

1. You must comply with the mandatory provisions. The remaining prescriptive provisions are all available for trade-off as long as you can meet the minimum savings requirement. 2. If it is designed and will be occupied that way then modeling that way makes sense.
