What’s the Buzz about Building Energy Benchmarking?

With the inauguration of Ontario’s Energy and Water Use Reporting Policy combined with the imminent launch of NRCan’s ENERGY STAR Certification for Commercial and Institutional buildings, 2018 is ramping up to be the year of ENERGY STAR Portfolio Manager.

We’ve heard time and time again that one cannot manage what they don’t measure. The practice of Building Energy Benchmarking is becoming increasingly popular as building owners become aware of the operational savings that can be realized through conservation efforts. These opportunities become apparent when energy use is properly tracked and measured. 

While large, multi-national organizations often have resources like energy analysts or managers dedicated specifically to tracking energy use, many organizations struggle to divert financial and human resources from their main lines of business to address energy efficiency.

Starting July 1st of this year, C&I buildings larger than 250,000 sq ft will be required by law to report their energy and water consumption to Ontario’s Ministry of Energy. The tool that will be used to collect and communicate the energy consumption data of eligible buildings is ENERGY STAR Portfolio Manager.

ENERGY STAR Portfolio Manager is a free tool commissioned by Natural Resources Canada to help property managers take charge of the energy use of their portfolio.

In 3 simple steps you could be on your way to benchmarking the energy use of your building or portfolio.


1)       Create an ENERGY STAR Portfolio Manager  account

2)      Populate your account with building characteristics (Size, Age, Type, etc.)

3)      Input 12 consecutive months of energy data


Once these steps have been completed your building could be eligible to receive an ENERGY STAR Score. This score will allow you to perform an “apples-to-apples” comparison of your buildings energy performance in relation to others across Canada.

Ask us how a Licensed Professional can help you fulfill the requirements of the new ENERGY STAR Certification application which, when accepted, grants building owners the privilege of displaying the ENERGY STAR  symbol in their building as a means of showcasing the building’s high performance.
