O11970/2401 W GRACE ST/CHICAGO/IL's ENERGY STAR score of 75 compares with an average of 69 across the 320 that report a score; it scores higher than 51% of them and lower than 47%. Its site EUI of 55.5 kBtu/ft² is about 21% 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 5.9 kgCO₂e/ft² is about 21% below the group average of 7.5 kgCO₂e/ft².
At 93,089 sq ft, it is about 81% below the average floor area of 488,124 sq ft for those buildings. It was built in 2000, 44 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 O11970/2401 W GRACE ST/CHICAGO/IL's energy performance changed over time?
BuildingCensus holds 8 Chicago disclosures for O11970/2401 W GRACE ST/CHICAGO/IL, covering report years 2015, 2016, 2017, 2018, 2019, 2020, 2022, 2023. Its ENERGY STAR score went from 95 in 2015 to 75 in 2023 (-20 points); its best year on file was 2015, at 95. Site EUI moved from 50.5 kBtu/ft² (2015) to 55.5 kBtu/ft² (2023), an 10% increase. Reported emissions went from 665 tCO₂e to 551 tCO₂e over the same span (down 17%).
What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 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. O11970/2401 W GRACE ST/CHICAGO/IL's 55.5 kBtu/ft² across 93,089 sq ft works out to about 5.2 billion Btu (1,514 MWh-equivalent) in 2023. Its source EUI of 118.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 934,757 kWh of electricity, 19,765 therms of natural gas and 487 thousand gallons of water for the year.
Which law requires O11970/2401 W GRACE ST/CHICAGO/IL to report its energy use?
O11970/2401 W GRACE ST/CHICAGO/IL 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:260132:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
