Office Building - submeter and exclude kitchen/cafe space & kwh

It's that simple. Ideally you add the submeter before your performance period, so you can subtract out accurate data.

Petros, Does this cafeteria serve the regular building occupants? You may want to check with Energy Star directly to see if they would sanction the exclusion of this energy, since cafeterias are commonly present in office buildings, and it's not clear to me how this would fit with their benchmarking rules. Particularly since there is only one tenant in this building, it would be hard to make the case that the cafeteria is under separate control (even if a third-party is contracted to run it, it sounds like it is in the service of the sole tenant).
