Advanced energy metering

Intent

To support energy management and identify opportunities for additional energy savings by tracking building-level and system-level energy use.

Requirements

Install advanced energy metering for the following:

• all whole-building energy sources used by the building; and
• any individual energy end uses that represent 10% or more of the total annual consumption of the building.

The advanced energy metering must have the following characteristics.

• Meters must be permanently installed, record at intervals of one hour or less, and transmit data to a remote location.
• Electricity meters must record both consumption and demand. Whole-building electricity meters should record the power factor, if appropriate.
• The data collection system must use a local area network, building automation system, wireless network, or comparable communication infrastructure.
• The system must be capable of storing all meter data for at least 36 months.
• The data must be remotely accessible.
• All meters in the system must be capable of reporting hourly, daily, monthly, and annual energy use.
