JLR was retained by Natural Resources Canada’s (NRCan) Office of Energy Efficiency to provide an analysis of the end use of energy in commercial and institutional (C&I) buildings across Canada in the form of energy use intensity (energy consumed per unit of floor space). One of goals was to provide more detailed breakdown of energy use with the buildings, and evaluate if energy use has changed.

The study involved collecting measured energy use from 50 C&I buildings (offices, hospitals, retail, long-term care, schools, and university buildings) and deriving energy-end use from utility data.

Advanced analytic techniques were developed by JLR and used to subdivide hourly measured data into 25 end-use categories. Fifteen of the buildings were then modeled and models verified against the utility data. Furthermore, five of the modeled buildings were audited to facilitate a more accurate breakdown. The project provided verified examples of energy use in a selection of building types and locations. It also revealed that electricity appears to be an increasing percentage of energy use within Canadian buildings.
