How has Ontario's energy performance changed over time?
BuildingCensus holds 13 Washington, DC disclosures for Ontario, covering report years 2012–2024. Site EUI moved from 18.3 kBtu/ft² (2012) to 54.0 kBtu/ft² (2024), an 195% increase. Reported emissions went from 17 tCO₂e to 45 tCO₂e over the same span (up 165%).
What does a site EUI of 54.0 kBtu/ft² mean?
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Ontario's 54.0 kBtu/ft² across 13,722 sq ft works out to about 0.7 billion Btu (217 MWh-equivalent) in 2024. Its source EUI of 84.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 62,671 kWh of electricity, 5,276 therms of natural gas and 346 thousand gallons of water for the year.
Which law requires Ontario to report its energy use?
Ontario reports under the Clean and Affordable Energy Act / BEPS, the legal basis of Washington, DC's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record dc:PM4178735:2024). DC's Building Energy Performance Standards (BEPS) require buildings below the performance standard to improve over compliance cycles (the first ends December 31, 2026; later cycles run five years), with penalties for buildings that fail to meet their pathway.
