If there are discrepancies between projected energy use and actual use, identify the cause and follow the M&V plan for corrective action. Discrepancies may result from inaccuracies in the simulation model, actual building use that differs from anticipated occupancy, improperly functioning equipment, and switches and controls not being properly calibrated.
The M&V provider writes the M&V plan. If possible, involve the facility’s operational staff in writing the plan. The plan should lay out the measurement and response protocol. The M&V plan must define the following:
Baseline energy use
Post-construction energy use
Any adjustments that should be made to the baseline energy use
