Whole-Building Energy Monitoring Requirements

Electricity meters must be capable of metering and recording total project electricity use at 15minute intervals. Refer to ASHRAE 90.1, Sections 8.4.3.1.

For all other fuels, provide measurement devices capable of monitoring whole-building energy use for each building energy source at least monthly. Include all energy sources supplied to the building from outside the project boundary. Refer to ASHRAE 90.1-2019 10.4.6.1 or ASHRAE 90.1-2022 10.4.7.1.

Electricity Submetering Requirements (ASHRAE 90.1, Section 8.4.3.1)

Projects must submeter end-use electricity data at 15-minute intervals for HVAC, interior lighting, exterior lighting, and receptacle; and if using ASHRAE 90.1-2022 - refrigeration systems.

Combine electricity end-uses less than 10% of the whole-building electrical load with other categories. For example, if exterior lighting loads are less than 10% of the whole-building load, teams can report exterior lighting with interior lighting. Use the energy end-use estimation from EAp1: Operational Carbon Projection and Decarbonization Plan to determine applicable loads.

ASHRAE Standard 90.1 Tenant Electricity Submetering (ASHRAE 90.1, Section 8.4.3.1)

Tenant spaces larger than 10,000 sq. ft. (929 sq. m.) require electricity submetering at 15minute intervals, both for total tenant electricity use, and for direct tenant loads for HVAC, interior lighting, exterior lighting, receptacle, and if using ASHRAE 90.1-2022 - refrigeration systems. For acceptable grouping of end-uses, reference the building-level 10% exception.

Exclude electricity from shared HVAC equipment (e.g., a central air handling unit providing supply air to the tenant space) when determining the tenant submetering requirements. The estimated load must include electricity for system components in the tenant space such as fan coil units and variable air volume (VAV) terminals.

ASHRAE Standard 90.1 Reporting

Refer to ASHRAE 90.1, Sections 8.4.3.2 and 90.1-2019 10.4.6.1 or 90.1-2022 10.4.7.1 .

The monitoring system must include the capability to report total and sub-metered electricity data at least hourly, daily, monthly, and annually, and the capability of reporting whole-building
