King HS

How does King HS compare with other K-12 school buildings in Chicago?

The latest disclosures cover 543 K-12 school buildings in Chicago, out of 3,852 buildings citywide. King HS's ENERGY STAR score of 38 compares with an average of 45 across the 365 that report a score; it scores higher than 42% of them and lower than 56%. Its site EUI of 91.7 kBtu/ft² is about 26% above the average of 72.7 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 6.9 kgCO₂e/ft² is about 11% above the group average of 6.2 kgCO₂e/ft².

At 310,545 sq ft, it is about 155% above the average floor area of 121,824 sq ft for those buildings. It was built in 1971, 28 years later 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 King HS's energy performance changed over time?

BuildingCensus holds 6 Chicago disclosures for King HS, covering report years 2018–2023. Its ENERGY STAR score went from 94 in 2020 to 38 in 2023 (-56 points); its best year on file was 2020, at 94. Site EUI moved from 62.5 kBtu/ft² (2020) to 91.7 kBtu/ft² (2023), an 47% increase. Reported emissions went from 1,031 tCO₂e to 2,142 tCO₂e over the same span (up 108%).

What does an ENERGY STAR score of 38 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 38 means the building performs better than about 38% of its national peers. BuildingCensus bands the score into report-card grades; 38 falls in band D — lowest band (1–54). It sits 37 points below 75, the threshold for ENERGY STAR certification. 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. King HS's 91.7 kBtu/ft² across 310,545 sq ft works out to about 28.5 billion Btu (8,346 MWh-equivalent) in 2023. Its source EUI of 137.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,124,365 kWh of electricity and 212,322 therms of natural gas for the year.

Which law requires King HS to report its energy use?

King HS 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:101572:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
