Twelve months of data from the metered categories is used to calibrate the computer simulation model. The M&V plan shall demonstrate the ability to identify specific problem areas if discrepancies exist between the modeled and metered data. When calibrating the as-built energy model, weather patterns must be reflected. You may be able to obtain this through the BMS. Calibration changes will also include occupancy and operational adjustments to reflect actual usage.

The calibrated energy simulation gives the owner and facility operator a true picture of savings from the ECMs instead of the predicted savings from the energy model developed during design. A simulation model developed during design makes a lot of assump

The calibrated energy simulation gives the owner and facility operator a true picture of savings from the ECMs instead of the predicted savings from the energy model developed during design. A simulation model developed during design makes a lot of assumptions on occupancy patterns, set points and weather. A calibrated energy model replaces those assumptions with real data while accommodating unforeseen program changes. If the actual results are greater than 10% from the predicted ones, compare the differences between the assumptions and the actual settings.
