Its site EUI of 65.2 kBtu/ft² is roughly in line with the average of 72.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 6.0 kgCO₂e/ft² is roughly in line with the group average of 5.8 kgCO₂e/ft².
At 47,480 sq ft, it is about 77% below the average floor area of 206,097 sq ft for those buildings. It was built in 1930, 41 years earlier than the group's average year built (1971).

How has The Bostonian's energy performance changed over time?
BuildingCensus holds 7 Chicago disclosures for The Bostonian, covering report years 2016–2022. Its ENERGY STAR score went from 89 in 2016 to 67 in 2022 (-22 points); its best year on file was 2017, at 90. Site EUI moved from 40.4 kBtu/ft² (2016) to 65.2 kBtu/ft² (2022), an 61% increase. Reported emissions went from 372 tCO₂e to 286 tCO₂e over the same span (down 23%).
What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. 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 Bostonian's 65.2 kBtu/ft² across 47,480 sq ft works out to about 3.1 billion Btu (907 MWh-equivalent) in 2022. Its source EUI of 125.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 452,208 kWh of electricity and 15,519 therms of natural gas for the year.
Which law requires The Bostonian to report its energy use?
The Bostonian 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 2022 disclosure (source record chicago:175229:2022). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
