Maybe I am overly cautious, but I would like to clarify the following. The Ref.Guide states "base building-level" energy meters.
Does this mean the meters should only measure common areas and systems that are under direct control of the owner? Meaning, receptacles, lights etc. in tenant areas must be excluded? Or can just the main meter be used, which includes tenant consumption as well?
If tenants need to be excluded I assume it is allowable to deduct tenant meter readings from the main meter, correct?
