EXCLUSIONS FOR ELECTRIC OR THERMAL STORAGE CHARGING

For projects that have on-site electric or thermal storage, the peak period can be selected during a time when these systems are not being charged if the following criteria can be demonstrated for the project.

• Separate metering . Systems must be separately metered or be capable of providing an accurate estimate of the conditions for the historical reporting year and current reporting year.

• Timing of system charge . Systems cannot be charged during either the peak electric grid demand or the peak electric grid emissions period.

Option 1. Electric Demand Reduction

This option requires a 10% reduction in the sum of monthly peak demand for the two months with highest demand, comparing the current reporting year to the historical baseline reporting period.

EXCLUDED ELECTRIC DEMAND FOR TENANT SPACES OR SPACES WITHOUT HOURLY METERING

If tenant peak demand data is not accessible to the building owner or facilities manager, or hourly metering is not available for some spaces, this data may be excluded for up to 20% of the project’s gross floor area (GFA). This encompasses all area excluded from EAp2: Energy Monitoring and Reporting . Equipment or amenities serving a significant proportion of the project’s occupants such as dedicated outside air systems, elevators, or commercial kitchen equipment in a shared cafeteria space cannot be excluded from hourly metering.

ELECTRIC DEMAND METERING CRITERIA

Types of metered data To document peak demand, use monthly utility bills that indicate peak demand, power metering from the project’s building automation system (BAS), or a stand-alone electricity monitoring system.

Use either hourly peak electric demand or 15-minute peak electric demand consistently for all reported data.

Multiple meters Buildings that use multiple meters to report monthly peak demand can demonstrate compliance using one of the following approaches:
