How does The Wrigley Building compare with other office buildings in Chicago?
The latest disclosures cover 387 office buildings in Chicago, out of 3,852 buildings citywide. The Wrigley Building's ENERGY STAR score of 76 compares with an average of 69 across the 320 that report a score; it scores higher than 53% of them and lower than 43%. Its site EUI of 64.0 kBtu/ft² is roughly in line with 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 6.2 kgCO₂e/ft² is about 17% below the group average of 7.5 kgCO₂e/ft².
At 661,275 sq ft, it is about 35% above the average floor area of 488,124 sq ft for those buildings. It was built in 1921, 35 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 The Wrigley Building's energy performance changed over time?
BuildingCensus holds 8 Chicago disclosures for The Wrigley Building, covering report years 2016–2023. Its ENERGY STAR score went from 77 in 2016 to 76 in 2023 (-1 points); its best year on file was 2019, at 91. Site EUI moved from 91.7 kBtu/ft² (2016) to 64.0 kBtu/ft² (2023), a 30% decrease. Reported emissions went from 6,201 tCO₂e to 4,125 tCO₂e over the same span (down 33%).
What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 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. The Wrigley Building's 64.0 kBtu/ft² across 661,275 sq ft works out to about 42.3 billion Btu (12,403 MWh-equivalent) in 2023. Its source EUI of 124.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,339,912 kWh of electricity, 206,751 therms of natural gas and 6,955 thousand gallons of water for the year.
Which law requires The Wrigley Building to report its energy use?
The Wrigley Building 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:101920:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
