Over half of Toronto’s greenhouse gas emissions are generated from buildings, and improving their energy efficiency is key to achieving the City’s greenhouse gas emissions reduction target to net zero by 2050, or sooner.

The Province of Ontario’s Energy & Water Reporting and Benchmarking (EWRB) regulation is designed to help building owners and managers improve their building’s energy and water efficiency.

Through this regulation, some privately owned buildings (greater than 50,000 square feet) will be required to report annual energy and water consumption and performance data.

Full details on the regulation can be found on Ontario’s EWRB Guide.

 

Information such as building characteristics and monthly energy and water consumption data for the previous calendar year will need to be reported by July 1st of each year.

For a complete list of the data elements you need to gather and report, refer to Ontario’s EWRB Guide.

Building owners are required to create an online account and report data to the Ministry of Energy through the ENERGY STAR® Portfolio Manager.

Download the Ontario Ministry of Energy  Portfolio Manager Guide to report under the EWRB regulation.

Training resources on the ENERGY STAR® Portfolio Manager can be accessed at Natural Resources Canada.
