Its site EUI of 46.6 kBtu/ft² is about 34% 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 4.9 kgCO₂e/ft² is about 35% below the group average of 7.5 kgCO₂e/ft².
At 92,741 sq ft, it is about 81% below the average floor area of 488,124 sq ft for those buildings. It was built in 1893, 63 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 210-220 N Green St.'s energy performance changed over time?
BuildingCensus holds 8 Chicago disclosures for 210-220 N Green St., covering report years 2016–2023. Its ENERGY STAR score went from 91 in 2016 to 96 in 2023 (+5 points). Site EUI moved from 44.9 kBtu/ft² (2016) to 46.6 kBtu/ft² (2023), an 4% increase. Reported emissions went from 679 tCO₂e to 453 tCO₂e over the same span (down 33%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 falls in band A — high performer (85–100). 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. 210-220 N Green St.'s 46.6 kBtu/ft² across 92,741 sq ft works out to about 4.3 billion Btu (1,267 MWh-equivalent) in 2023. Its source EUI of 97.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 753,043 kWh of electricity and 17,566 therms of natural gas for the year.
Which law requires 210-220 N Green St. to report its energy use?
210-220 N Green St. 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:130442:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
