Energy: Water Reporting and Benchmarking

With the cancellation of the Green Energy and Green Economy Act, you may think that all of the requirements under this act have disappeared.  This is not the case in all instances.  For example, Ontario Regulation (O.Reg.) 20/17: Ontario’s Reporting of Energy Consumption and Water Use has been moved to the Electricity Act 1998 as O.Reg. 506/18: Reporting of Energy Consumption and Water Use.

Multi Res Apartment Buildings

The reporting schedule has not changed.

  • July 1, 2018: Buildings over 250,000 ft² were required to report.
  • July 1, 2019: Buildings over 100,000 ft² have to report on their 2018 consumption.
  • July 1, 2020: Buildings over 50,000 ft² have to report on their 2019 consumption.
  • July 1, 2020: Multi-Residential buildings over 10 units.

Reporting is required on an annual basis for all buildings, with a few exceptions:

  • Government Buildings (Federal, Provincial, Municipal), which are covered under different legislation.
  • Industrial Buildings that meet certain criteria.
  • Agriculture Buildings that meet certain criteria.
  • Data Centres that meet certain criteria.

Multi-residential buildings were exempt in previous reporting periods, but are now required to report if they meet the building area or number of units.

Last year (July 2018 reporting on 2017 consumption), approximately 1,000 buildings in Ontario had to report.  With the drop in building size and the inclusion of multi-residential buildings, 10,000 buildings will have to report.

This is an update to a previous article on Energy and Water Reporting for Large Buildings.
