Its ENERGY STAR score went from 48 in 2015 to 73 in 2023 (+25 points); its best year on file was 2022, at 76. Site EUI moved from 88.5 kBtu/ft² (2015) to 77.8 kBtu/ft² (2023), a 12% decrease.

What does an ENERGY STAR score of 73 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 73 means the building performs better than about 73% of its national peers. BuildingCensus bands the score into report-card grades; 73 falls in band B — above median (70–84). It sits 2 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. Imperial Towers's 77.8 kBtu/ft² across 1,126,000 sq ft works out to about 87.6 billion Btu (25,674 MWh-equivalent) in 2023. Its source EUI of 95.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,601,949 kWh of electricity and 786,842 therms of natural gas for the year.
Which law requires Imperial Towers to report its energy use?
Imperial Towers 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:243596:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
