1. 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

2. 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

3. Tenant Billing & Cost Allocation
CB Richard Ellis Report – “Do Green Buildings Make Sense” November 2009
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)
“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,
reduce electric demand by 10 percent through demand aggregation.
10 percent reduction in electricity use was realized
