Schools-EBOM-v4 EAc5: Advanced energy metering

  • Likely to take time and planning

    On the surface, the basic credit requirements to meter whole building energy sources and major energy end uses seem accessible. 

    However, the requirements for advanced metering are more rigorous than standard practice. For example, all metering for your building energy sources— including electricity, gas, steam, and so on—must be connected to a communications infrastructure such that you can access the data remotely.

    Many buildings with utility owned meters will not meet this component of the credit requirements, even though all of the energy sources are separately metered.

    In addition, all energy sources and major sub-systems that make up at least 20% of the annual energy consumption must be separately metered according to the advanced metering requirements. This includes taking meter readings at specific intervals with specific reporting and communication capabilities. You’ll also need to develop a baseline for energy demand and consumption via historic data or energy modeling for each meter, and then program the building automation system (BAS)A building automation system (BAS) uses computer-based monitoring to coordinate, organize, and optimize building control subsystems, including lighting, equipment scheduling, and alarm reporting. to generate an alarm if the actual consumption/demand is more than 5% higher than the predicted baseline. 

    Overall, this credit requires an integrated approach to energy management and metering and will likely require a significant amount of time and planning to implement if your building does not already comply.

    What’s New in LEED v4

    • System-level metering and building automation systems, which were included in LEED 2009 as MPR#6 and as EAc3.1: Performance Measurement—Building Automation System, have been combined into this credit.

    Readiness Review Questions

    • What energy sources and major energy end uses are already submetered?
    • Do meters log data at intervals of one hour or less?
    • Is there a building automation system (BAS) in place? If so, submeteringSubmetering is used to determine the proportion of energy use within a building attributable to specific end uses or subsystems (e.g., the heating subsystem of an HVAC system). can be integrated into the existing BAS. 

    • Does the data collection system meet the credit requirements? For example, can meter data be stored for at least 36 months? Do electricity meters record demand energy use in addition to consumption?
    • Does the building energy management system have the required alarm capabilities?


    Are tenant spaces considered to be an “energy end use”? In other words, can we achieve this credit by metering tenant energy consumption?

    Tenant energy use is not considered to be an energy end use because tenant meters typically monitor energy use for lighting, plug loads, and occasionally other equipment such as supplemental cooling. Because of that, a single system is typically not represented by tenant-level metering, and therefore cannot qualify as an end use for the purposes of this credit.

  • EA Credit 5: Advanced energy metering


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



    Install advanced energy metering for the following:

    • all whole-building energy sources used by the building; and
    • major end uses that represent 20% or more of the total annual consumption of the building minus plug load use.

    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.


    Program the facility’s energy management system to set an alarm whenever the energy consumption and peak demand rise above the anticipated amount by more than 5%. The anticipated consumption and peak should be determined by analyzing historical facility performance and weather and operating conditions and should be set on at least monthly, preferably daily.

    Demand measurements must be taken in time increments no longer than the increments used for utility billing or in one-hour increments, whichever is less time.

    On at least a monthly basis, report the facility’s utility peak demand and total consumption and compare it with the data for the previous month and the same month from the previous year.
