EnerCare Connections Case Study – Energy Use Reduction after the Introduction of Sub-metering

This study reflects the changes in energy use by occupants of suites before and after the introduction of sub-metering in two buildings – one building with 147 residential units and the other with 161 residential units.

In both buildings, suite meters were installed for all units at the same time; however the individual suites were introduced to sub-metered billing over the course of about 4 years.

This means that at any given time, there was a mixture of tenants who were responsible for paying for their own electric bill and those who were not. The two graphs below illustrate the difference in energy use (in kWh) between those who were not paying for their own electrical use, and those who were responsible for paying their own electric bill.

This information was broken down to reflect the changes based on 1 Bedroom, 2 Bedrooms, and 3 Bedrooms as well as overall averages.
