At 471,436 sq ft, it is roughly in line with the average floor area of 488,124 sq ft for those buildings. It was built in 2008, 52 years later than the group's average year built (1957). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 22 West Washington's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 22 West Washington, covering report years 2014–2023. Its ENERGY STAR score went from 54 in 2014 to 82 in 2023 (+28 points); its best year on file was 2016, at 88. Site EUI moved from 110.0 kBtu/ft² (2014) to 85.7 kBtu/ft² (2023), a 22% decrease. Reported emissions went from 11,435 tCO₂e to 5,653 tCO₂e over the same span (down 51%).
What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. 22 West Washington's 85.7 kBtu/ft² across 471,436 sq ft works out to about 40.4 billion Btu (11,841 MWh-equivalent) in 2023. Its source EUI of 239.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 11,839,756 kWh of electricity and 7,806 thousand gallons of water for the year.
Which law requires 22 West Washington to report its energy use?
22 West Washington 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:103698:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
