Sullivan HS

How does Sullivan 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. Sullivan HS's ENERGY STAR score of 56 compares with an average of 45 across the 365 that report a score; it scores higher than 67% of them and lower than 32%. Its site EUI of 83.3 kBtu/ft² is about 15% 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 5.8 kgCO₂e/ft² is roughly in line with the group average of 6.2 kgCO₂e/ft².

At 218,067 sq ft, it is about 79% above 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 Sullivan HS's energy performance changed over time?

BuildingCensus holds 9 Chicago disclosures for Sullivan HS, covering report years 2015–2023. Its ENERGY STAR score went from 66 in 2015 to 56 in 2023 (-10 points); its best year on file was 2015, at 66. Site EUI moved from 89.2 kBtu/ft² (2015) to 83.3 kBtu/ft² (2023), a 7% decrease. Reported emissions went from 1,481 tCO₂e to 1,265 tCO₂e over the same span (down 15%).

What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 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. Sullivan HS's 83.3 kBtu/ft² across 218,067 sq ft works out to about 18.2 billion Btu (5,324 MWh-equivalent) in 2023. Its source EUI of 115.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,013,776 kWh of electricity and 147,122 therms of natural gas for the year.

Which law requires Sullivan HS to report its energy use?

Sullivan 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:158841:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
