How does 2929 W 83rd St 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. 2929 W 83rd St's ENERGY STAR score of 100 compares with an average of 45 across the 365 that report a score; it scores higher than 99% of them. Its site EUI of 21.1 kBtu/ft² is about 71% 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 1.7 kgCO₂e/ft² is about 73% below the group average of 6.2 kgCO₂e/ft².

At 85,634 sq ft, it is about 30% below the average floor area of 121,824 sq ft for those buildings. It was built in 1958, 15 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.

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 2929 W 83rd St's 21.1 kBtu/ft² across 85,634 sq ft works out to about 1.8 billion Btu (530 MWh-equivalent) in 2022. Its source EUI of 35.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 184,060 kWh of electricity and 11,802 therms of natural gas for the year.

Which law requires 2929 W 83rd St to report its energy use?

2929 W 83rd St 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 2022 disclosure (source record chicago:257035:2022). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
