Metering vs. Submetering
• What is submetering?
- Defined as a metering device installed after the main utility meter
 Used for capturing facility energy data at a specific location,
panel, circuit or user.
- Delivers granularity of facility energy performance data
Submeters –The critical component for accessing facility
energy related data
Submetering Applications
• Historical Applications
- Tenant billing
- Cost allocation
- Energy management
• Growth Applications
- Measurement & Verification
- Green buildings
- Building automation
- Carbon footprint analysis
- Renewable energy
- Power Quality Analysis
- Predictive Maintenance
Tenant Billing & Cost Allocation
• CB Richard Ellis Report – “Do Green Buildings Make Sense” November 2009
http://catcher.sandiego.edu/items/business/Do_Green_Buildings_Make_Dollars_and_Sense_
draft_Nov_6_2009.pdf
- A separately metered building, where tenants pay for what they
consume, will have
lower energy costs by 21% on average even if the Energy Star score is the same. That is,
when you pay for what you consume, you become much more frugal.
• New York State Energy Research and Development Authority Residential Electrical
Submetering Manual (October 1997, revised October 2001)
http://www.submeteronline.com/pdf/subman2001.pdf
- “the change from master-metering to submetering typically reduces the consumption of
electricity in apartments by 10-26 percent.”
• U.S. Environmental Protection Agency, in a 2002 paper “Submetering Energy Use in Colleges
and Universities: Incentives and Challenges,
http://www.oakland.edu/upload/docs/Energy/EPA%20EnergyStar%20Submeter%20Report.pdf
- reduce electric demand by 10 percent through demand aggregation.
- 10 percent reduction in electricity use was realized
