Introduce the M&V program into the design early in the process, because it can affect the design of the mechanical and electrical systems as well as the BMS. There is also inherent value in having the design teams think about how the building will be operated.
Talk to the facility operations staffabout the financial benefits and operational requirements of the M&V plan. Any energy savings achieved through M&V will depend on their participation.
Energy savings is determined by comparing actual metered or measured energy use to the projected energy use of a baseline building using the project's actual operating conditions.
Energy Savings = Projected Baseline Energy Use – Post-Construction Energy Use (actual metered energy use).
Post-Construction Energy Use is determined by utility metering or submetering, or by using an energy simulation model of the projected building.
Data to support calculations (Option B) or calibration of simulations (Option D) is taken from a combination of meters and sensors included in the building automation systems, and through temporary installation of additional sensors and data loggers as needed.
Determine whether IPMVP Option B or Option D is most appropriate for the project design. (Option C, which was allowed in earlier versions of LEED, is not allowed, as it is considered less accurate, and doesn't allow for M&V of individual energy conservation measures.)
Discuss as a team whether M&V will contribute to the project’s goals for energy reduction and systems monitoring. Consider the project size, its complexity, and whether you plan to run a whole-building energy model. Also think about how the building is likely to be operated. If the system is not likely to be fully utilized, it may not be an appropriate investment.
