NC-2009 EAp2: Minimum Energy Performance
Our building is 7 floors above ground with a conditioned basement and is about 70K ft2. It is all-electric, which would make it either System 6 or System 8, since it's not obvious which is the 'predominant' condition of the building, the height or the floor area.
Any guidance as to which system to use for the baseline would be most appreciated!

Yep it can get confusing, just pay close attention to the "and" / "or" in each Building Type category. In your situation since the project is greater than 5 floors it must be a system 8. A system 6 would be only applicable to 5 floors or less. So number of floors and/or the area is the order of evaluation, except anything over 150,000 sf no matter how many floors is a system 7/8.
