As stated in the LEED Reference Guide, the following items must be monitored:

lighting systems and controls
constant and variable motor loads
variable-frequency-drive operation
chiller efficiency at variable loads
cooling load
air and water economizer and heat recovery cycles
air distribution static pressures and ventilation air volumes
boiler efficiencies
building-related process energy systems and equipment
indoor water risers and outdoor irrigation system.

Determine the systems and equipment that need to be monitored and metered, as well as the number of meters required. (See the list of Commonly Monitored Items in the Documentation Toolkit.) 

Create a baseline for comparison to actual measured data. The baseline depends on your building type, its complexity, and the IPMVP option you’ve chosen. Your baseline will be either the whole building or space, or system-specific, and in accordance with the extent of the M&V plan you previously developed. Projected baseline energy usage can be determined by using energy-efficiency standards or guidelines. If your project is a retrofit, the baseline will be the usage for systems in place before renovation began. 

Case 2: Projects with 75% or more of total building area

Verify that process water is being submetered, along with lighting, plug loads, heating and cooling. Process water is the only water that needs to be submetered, water for restrooms, kitchens, and janitorial rooms doesn’t need to be submetered. Process water is the only water that needs to be submetered. Process water includes water used for cooling, heating, and domestic hot water. Water for tenant uses such as restrooms, janitorial purposes, and break rooms does not need to be submetered. 

Case 1: Projects with less than 75% of total building area

Implementing M&V into your project after mechanical and electrical systems have been designed can cause this credit to become cost-prohibitive due to redesign costs.

The payoff of the investment in an M&V program comes while the building is in use. However, there is a danger that operations and maintenance staff will not be prepared to understand the significance of data trends reported by the submetering or measurement system, or won’t have the time to investigate anomalies that aren’t causing immediate problems. Consider how your building is likely to be operated when planning and designing your M&V program—commitment from the owner is the key to success.

The M&V provider should work with the MEP to verify that all mechanical and electrical systems have the capability, and are designed, to allow metering and submetering. In addition, these systems must be designed to properly interface with any BMS or submetering installed. The M&V provider can verify that the M&V systems installed are capable of providing the information required for the credit.
