Ontario (2245)'s ENERGY STAR score of 90 compares with an average of 76 across the 1,305 that report a score; it scores higher than 51% of them and lower than 47%. Its site EUI of 58.9 kBtu/ft² is about 11% above the average of 53.2 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 3.8 kgCO₂e/ft² is about 16% above the group average of 3.3 kgCO₂e/ft².
At 131,924 sq ft, it is roughly in line with the average floor area of 124,053 sq ft for those buildings. It was built in 2007, 16 years later than the group's average year built (1991). Across all 24 jurisdictions BuildingCensus covers, the 3,025 retail store buildings average an ENERGY STAR score of 73 and a site EUI of 57.7 kBtu/ft².
How has Ontario (2245)'s energy performance changed over time?
BuildingCensus holds 7 California disclosures for Ontario (2245), covering report years 2018–2024. Its ENERGY STAR score went from 65 in 2018 to 90 in 2024 (+25 points); its best year on file was 2022, at 91. Site EUI moved from 66.8 kBtu/ft² (2018) to 58.9 kBtu/ft² (2024), a 12% decrease. Reported emissions went from 605 tCO₂e to 505 tCO₂e over the same span (down 16%).
What does an ENERGY STAR score of 90 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In California, 65% of scored buildings are at 75 or above.
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 (2245)'s 58.9 kBtu/ft² across 131,924 sq ft works out to about 7.8 billion Btu (2,277 MWh-equivalent) in 2024. The disclosure also reports 1,373,072 kWh of electricity and 12,425 therms of natural gas for the year.
