Electric vehicle chargers Separately metered energy for Electric Vehicle Service Equipment (EVSE) used to recharge vehicles may be excluded from the total project metered energy use. If it is not sub-metered, ESPM adjusts the score for estimated EVSE usage.

EMERGENCY SUPPORT SYSTEMS

Metering is not required for fuel input to emergency support systems that generate electricity, heating, or cooling upon failure of the primary system in a power outage or extreme temperature event. Emergency support systems are not exempt for locations where power outages commonly occur for more than 200 hours per year.

Additional considerations: Optional additional metering

Additional metering not required for this prerequisite can support achievement of credit compliance for the other EA credits.

 Interval meters capturing peak monthly electric demand or peak thermal heating and demand for the reporting period and a historical baseline year are required to document EAc4: Peak Load Reduction Performance .

 Sub-meters that capture energy use from data center spaces, parking garages, or EVSE provide a more accurate benchmark comparison of the project’s energy use intensity and greenhouse gas emissions intensity.

 For projects with on-site renewable energy generation, meters that track the monthly portion generated and used on the site inform lower source energy use intensities for on-site renewable usage.

 EAc7: Commissioning, Option 2 requires incremental metering and software functionality, building on the requirements in this prerequisite.

Meter calibrations Meter calibrations are critical to maintaining accuracy in the recorded data. For any installed meter within the facility manager’s control, calibrate the devices based on the manufacturer’s recommended intervals. This requirement does not apply to utility-provided meters where the utility service provider holds responsibility for meter calibration.

Data recording Record monthly data for each energy source so that building owners and facility managers can access and use the data to make informed decisions on energy efficiency and carbon emission
