Its ENERGY STAR score went from 80 in 2014 to 77 in 2023 (-3 points); its best year on file was 2015, at 89. Site EUI moved from 58.0 kBtu/ft² (2014) to 47.7 kBtu/ft² (2023), a 18% decrease. Reported emissions went from 11,688 tCO₂e to 6,757 tCO₂e over the same span (down 42%).
What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 333 West Wacker's 47.7 kBtu/ft² across 1,012,961 sq ft works out to about 48.3 billion Btu (14,161 MWh-equivalent) in 2023. Its source EUI of 133.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 14,146,301 kWh of electricity and 8,618 thousand gallons of water for the year.
Which law requires 333 West Wacker to report its energy use?
333 West Wacker 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:101788:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
