Its ENERGY STAR score went from 61 in 2016 to 29 in 2023 (-32 points); its best year on file was 2016, at 61. Site EUI moved from 60.3 kBtu/ft² (2016) to 60.5 kBtu/ft² (2023), an 0% increase. Reported emissions went from 5,952 tCO₂e to 5,090 tCO₂e over the same span (down 14%).

What does an ENERGY STAR score of 29 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 29 means the building performs better than about 29% of its national peers. BuildingCensus bands the score into report-card grades; 29 falls in band D — lowest band (1–54). It sits 46 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. OneEleven (nl025, nl026)'s 60.5 kBtu/ft² across 810,402 sq ft works out to about 49 billion Btu (14,369 MWh-equivalent) in 2023. Its source EUI of 125.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,388,540 kWh of electricity, 204,232 therms of natural gas and 19,504 thousand gallons of water for the year.

Which law requires OneEleven (nl025, nl026) to report its energy use?

OneEleven (nl025, nl026) 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:160299:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
