Its ENERGY STAR score went from 57 in 2014 to 68 in 2023 (+11 points); its best year on file was 2020, at 70. Site EUI moved from 248.0 kBtu/ft² (2014) to 225.7 kBtu/ft² (2023), a 9% decrease. Reported emissions went from 9,472 tCO₂e to 6,804 tCO₂e over the same span (down 28%).

What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 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. Advocate Trinity Hospital's 225.7 kBtu/ft² across 367,395 sq ft works out to about 82.9 billion Btu (24,302 MWh-equivalent) in 2023. Its source EUI of 368.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,104,642 kWh of electricity and 552,547 therms of natural gas for the year.

Which law requires Advocate Trinity Hospital to report its energy use?

Advocate Trinity Hospital 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:102532:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
