The Rating System calls out to "Calibrate meters within the manufacturer’s recommended interval if the building owner, management organization or tenant owns the meter. Meters owned by third parties (e.g., utilities or governments) are exempt." There is not a whole lot of coverage in the "Checklists" portion of the website to adequately address this. It might be good to add for a project team's check list of things to do. For EAc1 as well!

For an actual question, as energy metering data may be excluded for up to 10% of the building’s gross floor area, are there any thoughts out there regarding the same exclusion for calibration for the excluded area? Based on my reading of the Ref Guide, I'm apt to say no exclusion for calibration of any meters.
