HighSchool_LeoHS's ENERGY STAR score of 94 compares with an average of 45 across the 365 that report a score; it scores higher than 96% of them and lower than 3%. Its site EUI of 54.0 kBtu/ft² is about 26% below the average of 72.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.5 kgCO₂e/ft² is about 44% below the group average of 6.2 kgCO₂e/ft².
At 111,882 sq ft, it is roughly in line with the average floor area of 121,824 sq ft for those buildings. It was built in 1926, 17 years earlier than the group's average year built (1943). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².
How has HighSchool_LeoHS's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for HighSchool_LeoHS, covering report years 2015–2023. Its ENERGY STAR score went from 48 in 2015 to 94 in 2023 (+46 points); its best year on file was 2021, at 96. Site EUI moved from 100.6 kBtu/ft² (2015) to 54.0 kBtu/ft² (2023), a 46% decrease. Reported emissions went from 602 tCO₂e to 391 tCO₂e over the same span (down 35%).
What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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 Chicago, 35% 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. HighSchool_LeoHS's 54.0 kBtu/ft² across 111,882 sq ft works out to about 6 billion Btu (1,771 MWh-equivalent) in 2023. Its source EUI of 69.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 236,124 kWh of electricity and 52,326 therms of natural gas for the year.
Which law requires HighSchool_LeoHS to report its energy use?
HighSchool_LeoHS reports under the Building Energy Use Benchmarking Ordinance, the legal basis of the Chicago Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record chicago:172053:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
