Its site EUI of 81.3 kBtu/ft² is about 13% above the average of 72.0 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.9 kgCO₂e/ft² is roughly in line with the group average of 5.8 kgCO₂e/ft².

At 530,632 sq ft, it is about 157% above the average floor area of 206,097 sq ft for those buildings. Its 1968 construction date is close to the group's average year built (1971).

How has Hawthorne House's energy performance changed over time?

BuildingCensus holds 9 Chicago disclosures for Hawthorne House, covering report years 2015–2023. Its ENERGY STAR score went from 19 in 2015 to 52 in 2023 (+33 points); its best year on file was 2017, at 89. Site EUI moved from 92.8 kBtu/ft² (2015) to 81.3 kBtu/ft² (2023), a 12% decrease. Reported emissions went from 5,069 tCO₂e to 3,119 tCO₂e over the same span (down 38%).

What does an ENERGY STAR score of 52 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 52 means the building performs better than about 52% of its national peers. BuildingCensus bands the score into report-card grades; 52 falls in band D — lowest band (1–54). It sits 23 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. Hawthorne House's 81.3 kBtu/ft² across 530,632 sq ft works out to about 43.1 billion Btu (12,643 MWh-equivalent) in 2023. Its source EUI of 116.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,790,621 kWh of electricity, 336,381 therms of natural gas and 14,060 thousand gallons of water for the year.

Which law requires Hawthorne House to report its energy use?

Hawthorne House 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:159637:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
