We are working on a multiple building campus, it's a residential project. We want to pursue EAc5.1 but we are not sure of which loads should be measured; since is a C&S, we understand that we should only provide submeters for the loads of the common areas, such as elevators, exterior lighting, right? I don't quite understand the definition of "base building".

You should measure what you need to measure to verify the energy savings claimed. If all of your savings are generated from things like elevators, exterior lighting, interior lighting in the core spaces, etc. then that is all you have to measure. In most C&S projects however there are other savings. For example, building envelope improvements which impact heating, cooling, fans, etc. related to the tenant spaces. Since you are modeling a fully occupied and complete facility the base building is the minimally code compliant version of your building.
So think in terms of building energy end uses, not just specific spaces.
