Energy Monitoring and Recording
ASHRAE STANDARD 90.1, MONITORING AND RECORDING REQUIREMENTS
Initial buildouts with at least 10,000 square feet (929 square meters) of gross building area shall meet ASHRAE Standard 90.1 energy monitoring and recording requirements:
Tenant energy monitoring requirements Electricity meters must be capable of metering and recording total project electricity use at 15minute intervals, excluding shared systems ( ASHRAE 90.1, Sections 8.4.3.1). 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. Include electricity for system components in the tenant space, such as fan coil units and VAV terminals.
For all other energy sources delivered directly to the project space from outside the building’s site boundary, provide measurement devices capable of monitoring energy use at least monthly. Examples include fuel, district heating, or district cooling delivered from a utility or from a campus energy plant directly to the project space.
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 -compliant refrigeration systems.
Electricity end uses that contribute less than 10% of total project electrical load may be excluded. For example, if tenant exterior lighting loads are less than 10% of total tenant electricity use, teams can report exterior lighting with interior lighting. Electricity end uses may also be excluded if the whole-building contribution of the end use comprises less than 10% of whole-building electricity use.
ASHRAE Standard 90.1 reporting ( ASHRAE 90.1, Section s 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 both total and submetered electricity data at least hourly, daily, monthly, and annually, and this data must be accessible to the operators of the space.
Third-party energy monitoring services or applications may be used to comply with the data reporting and data storage requirements.
