1) if there is a discrepancy between the actual main meter of the energy supplier and the submeter total (sub meter total is around 8 to 10% less), which data should we input for the portfolio manager? can we use the total from the main meter reading then appropriated into the percentage breakdown of service (HVAC, Lighting, Misc, etc) based on the submeter readings?
2) if the sub meters are due for calibration, will the data log still be valid or do they need to be calibrated before making any entries?
