New Report Finds the Conservation Impact of Sub-Metering Multi-Residential Buildings in Ontario is Significant: - MarketWatch (PDF)
EnerCare Connections Inc. ("EnerCare Connections"), a subsidiary of EnerCare Inc., retained Navigant to estimate the conservation impact of electricity sub-metering on multi-residential buildings in Ontario and estimate the "technical potential" of a provincial deployment of sub-metering for multi-residential buildings. The result is a comprehensive report entitled, Evaluation of the Impact of Sub-Metering on Multi-Residential Electricity Consumption and the Potential Economic and Environmental Impact on Ontario.
For this analysis, EnerCare Connections provided Navigant with electricity consumption data for 3,971 units in 22 buildings in Ontario covering the period from September 2009 through September 2011. Data from 672 of these units (i.e. those units that switched from bulk to sub-metering during the twenty-five month period) was used to estimate the conservation impact of sub-metering.
Navigant also studied the environmental benefit of sub-metering, specifically reduced greenhouse gas emissions. Navigant estimates the total cumulative reduction in greenhouse gas emissions if sub-metering were deployed in all currently bulk-metered multi-residential buildings from 2013 through 2017 could be more than four thousand kilotonnes, and from 2013 through 2032 could be approximately 22 thousand kilotonnes, approximately the same amount as was emitted by all vehicles in Ontario in 2007, based on Statistics Canada data.
