How does 25 E Washington compare with other office buildings in Chicago?
The latest disclosures cover 387 office buildings in Chicago, out of 3,852 buildings citywide. 25 E Washington's ENERGY STAR score of 84 compares with an average of 69 across the 320 that report a score; it scores higher than 78% of them and lower than 20%. Its site EUI of 54.4 kBtu/ft² is about 23% below the average of 70.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.6 kgCO₂e/ft² is about 25% below the group average of 7.5 kgCO₂e/ft².
At 497,964 sq ft, it is roughly in line with the average floor area of 488,124 sq ft for those buildings. It was built in 1914, 42 years earlier 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 25 E Washington's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 25 E Washington, covering report years 2014–2023. Its ENERGY STAR score went from 94 in 2014 to 84 in 2023 (-10 points); its best year on file was 2014, at 94. Site EUI moved from 46.0 kBtu/ft² (2014) to 54.4 kBtu/ft² (2023), an 18% increase. Reported emissions went from 3,798 tCO₂e to 2,788 tCO₂e over the same span (down 27%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. 25 E Washington's 54.4 kBtu/ft² across 497,964 sq ft works out to about 27.1 billion Btu (7,939 MWh-equivalent) in 2023. Its source EUI of 108.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,945,870 kWh of electricity for the year.
Which law requires 25 E Washington to report its energy use?
25 E 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:101881:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
