The M&V provider develops the M&V plan. If possible, involve the facility’s operational staff in writing the plan, which must define the following:

M&V system design;
meter locations and specifications;
one-line electrical schematics identifying end-use circuits;
and guidelines for tenant submetering.

General

The determination of systems to be monitored is building-specific rather than prescribed by the credit requirements. 

Whole-building calibration simulation requires information about the instruments that enable the project to monitor the categories listed in the IPMVP. 

To achieve this credit under Option D, the M&V program must be able to identify specific building performance issues. A BMS, or submetering, can build this capacity into your system.

If applicable, the BMS should be set up to collect data that allows 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 density, space use, and system settings. 

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 M&V provider works with the owner to determine the best system for monitoring actual energy use. 

Option D: Calibrated Simulation

The M&V provider works with the owner and the mechanical engineer to determine the best solution for metering or submetering ECMs.
