Its ENERGY STAR score went from 82 in 2016 to 43 in 2023 (-39 points); its best year on file was 2021, at 84. Site EUI moved from 66.2 kBtu/ft² (2016) to 82.8 kBtu/ft² (2023), an 25% increase.

What does an ENERGY STAR score of 43 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 43 means the building performs better than about 43% of its national peers. BuildingCensus bands the score into report-card grades; 43 falls in band D — lowest band (1–54). It sits 32 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. 20 N State's 82.8 kBtu/ft² across 211,608 sq ft works out to about 17.5 billion Btu (5,135 MWh-equivalent) in 2023. Its source EUI of 152.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,312,064 kWh of electricity and 96,265 therms of natural gas for the year.
Which law requires 20 N State to report its energy use?
20 N State 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:253967:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
