Its ENERGY STAR score went from 18 in 2014 to 12 in 2023 (-6 points); its best year on file was 2015, at 20. Site EUI moved from 298.0 kBtu/ft² (2014) to 307.0 kBtu/ft² (2023), an 3% increase. Reported emissions went from 56,241 tCO₂e to 40,317 tCO₂e over the same span (down 28%).

What does an ENERGY STAR score of 12 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 12 means the building performs better than about 12% of its national peers. BuildingCensus bands the score into report-card grades; 12 falls in band D — lowest band (1–54). It sits 63 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. Stroger Hospital Campus's 307.0 kBtu/ft² across 1,596,300 sq ft works out to about 490.1 billion Btu (143,624 MWh-equivalent) in 2023. Its source EUI of 502.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 48,234,660 kWh of electricity and 3,254,935 therms of natural gas for the year.

Which law requires Stroger Hospital Campus to report its energy use?

Stroger Hospital Campus 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:103630:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
