Jackson's ENERGY STAR score of 79 compares with an average of 69 across the 320 that report a score; it scores higher than 64% of them and lower than 32%. Its site EUI of 59.6 kBtu/ft² is about 15% 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 5.2 kgCO₂e/ft² is about 31% below the group average of 7.5 kgCO₂e/ft².
At 1,809,140 sq ft, it is about 271% above the average floor area of 488,124 sq ft for those buildings. It was built in 1928, 28 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 175 W. Jackson's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for 175 W. Jackson, covering report years 2014–2023. Its ENERGY STAR score went from 90 in 2014 to 79 in 2023 (-11 points); its best year on file was 2017, at 94. Site EUI moved from 87.0 kBtu/ft² (2014) to 59.6 kBtu/ft² (2023), a 31% decrease. Reported emissions went from 19,800 tCO₂e to 9,391 tCO₂e over the same span (down 53%).
What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 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. 175 W. Jackson's 59.6 kBtu/ft² across 1,809,140 sq ft works out to about 107.8 billion Btu (31,600 MWh-equivalent) in 2023. Its source EUI of 101.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 12,396,692 kWh of electricity, 375,839 therms of natural gas and 7,179 thousand gallons of water for the year.
Which law requires 175 W. Jackson to report its energy use?
175 W. Jackson 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:101731:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
