Discuss as a team whether M&V will contribute to your project’s goals for energy reduction and system monitoring. Consider your project’s size, its complexity, and your tenants’ needs. Also think about how the building will be operated. If the M&V program is not likely to be fully utilized by the tenants, it may not be an appropriate investment.

Provide a yearly summary report that identifies both energy performance issues and corrective actions.

Calibration of the energy model adds a small amount on top of the cost of the baseline, as-built, energy model.

Energy savings is verified by either comparing the calibrated, as-built model to the calibrated, baseline model—or by comparing calibrated, baseline energy use to actual metered energy use.

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 about 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 10% greater than the predicted ones, compare the differences between the assumptions and the actual settings.

Include actual occupancy and weather data when calibrating the energy simulation model after the building’s first-year energy usage data becomes available. The energy modeler performs the calibrated simulation with the assistance of the M&V provider. 

Set up the BMS to provide monthly reports as required by the M&V plan, if applicable. 

Option D: Calibrated Simulation

The ECM usage can be tracked on a simple spreadsheet; complicated calculations or modeling is not required.

The facilities manager or M&V provider compares baseline energy use of the ECMs to post-construction energy use.
