Operations & Maintenance

Meters and submeters should be recalibrated per manufacturers’ recommendations. 

Continue to reevaluate ongoing energy savings and correct any deviations, in line with the timeframe identified in your M&V plan. 

Implement your M&V program. If applicable, track and archive trending data with utility meter and energy submeter systems, as defined in your M&V plan.

All Cases

The payback period for a submetering program depends on its initial cost and whether the M&V program identifies inefficiencies that wouldn’t have been found otherwise—substantial fixes can pay for the metering system. The true return on investment, however, depends on the commitment of the tenant, owner, and operational staff.

Encourage the operations team to focus on running the building at optimal efficiency. 

Meters and submeters should be recalibrated periodically according to manufacturers’ recommendations.

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.
