Run a preliminary energy model. If an energy model is being developed for EAc1: Optimize Energy Performance, the model can be used as the energy-use baseline for your M&V plan. Or, a new model may be run to determine the baseline energy use. The actual energy use will be compared to this baseline.
The mechanical engineer designs and specifies the appropriate submetering devices, controls, and M&V system. The M&V provider verifies that the M&V program and systems are capable of providing the information required for the credit.
The M&V provider works with the mechanical engineer to verify that all systems are designed to allow metering and submetering. Meters and energy systems must be capable of interfacing with the selected BMS or metering system.
The M&V provider reviews the project design to determine which systems and equipment will be metered, and also determines how many meters will be required. See the guide to commonly metered items in the Documentation Toolkit.
