The payback period for M&V programs depends on the initial cost of additional meters and whether the program identifies inefficiencies that wouldn’t have been found otherwise. Some fixes may be substantial and will pay for the metering system. After the BMS or metering system has been installed, the true return depends on the commitment of the owner and operational staff. Because M&V monitors actual building operation over time, M&V procedures can lead to valuable operational savings by uncovering building system design, installation, and control issues not caught by commissioning.
