How has O'Hare Plaza II's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for O'Hare Plaza II, covering report years 2014–2022. Its ENERGY STAR score went from 89 in 2014 to 78 in 2022 (-11 points); its best year on file was 2015, at 93. Site EUI moved from 59.0 kBtu/ft² (2014) to 57.6 kBtu/ft² (2022), a 2% decrease. Reported emissions went from 3,039 tCO₂e to 1,941 tCO₂e over the same span (down 36%).
What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. O'Hare Plaza II's 57.6 kBtu/ft² across 516,010 sq ft works out to about 29.7 billion Btu (8,711 MWh-equivalent) in 2022. Its source EUI of 161.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,319,827 kWh of electricity and 0 therms of natural gas for the year.
Which law requires O'Hare Plaza II to report its energy use?
O'Hare Plaza II 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 2022 disclosure (source record chicago:158095:2022). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
