Energy & Water Reporting and Benchmarking: Large Buildings
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 of 80% by 2050.
The Province of Ontario’s Energy and Water Reporting & Benchmarking (EWRB) regulation, is designed to help building owners and managers improve their building’s energy and water efficiency. The first mandatory reporting deadline is July 1, 2018.
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.
Large multi-unit residential, commercial and some industrial buildings with a gross floor area of 50,000 square feet or more are required to report.
To see if your building is subject to the reporting requirements, consult the Municipal Property Assessment Corporation (MPAC) property codes.
Building owners are required to report their data to the Ministry of Energy by July 1 each year.The reporting requirement will be phased in over three years, beginning July 1, 2018, with buildings that are 250,000 square feet or more.
