The owner’s goals and IPMVP guidelines should drive the M&V plan, which should specify which systems are to be sub-metered and which are being spot metered, and how.
Coordinate with the mechanical and electrical engineers to verify that the control devices will be able to provide the information needed for credit compliance.
The industry standard for M&V plans, both in the U.S. and internationally, is the International Performance Measurement and Verification Protocol (IPMVP), owned by the nonprofit Efficiency Valuation Organization.
The BMS should be set up to collect data that will allow fair comparison between actual and predicted energy use. For example, since weather patterns are factored into the energy model, the BMS should capture these, along with other parameters such as operating schedule, occupancy
Sub-metering different use areas in mixed-use buildings, such as office and laboratory space, can offer insight into what energy reduction measures will be most appropriate for different use spaces.
Isolating and metering different ECMs, such as HVAC systems or lighting, can provide useful information on energy consumption and provide insight on energy reduction measures.
An M&V program that is implementedthroughout the life of the building will provide the highest return on investment. Design your M&V program for use throughout the life of the building to provide the highest return on investment.
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.
Any type of LEED AP can qualify the project for this credit, but a LEED AP with a specialized operations and maintenance credential (LEED AP O+M) would be the ideal choice for a LEED-EBOM project.
