The Jewelers Building's ENERGY STAR score of 72 compares with an average of 69 across the 320 that report a score; it scores higher than 43% of them and lower than 54%. Its site EUI of 66.5 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 6.4 kgCO₂e/ft² is about 15% below the group average of 7.5 kgCO₂e/ft².
At 621,390 sq ft, it is about 27% above the average floor area of 488,124 sq ft for those buildings. It was built in 1927, 29 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 Jewelers Building's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for The Jewelers Building, covering report years 2014–2023. Its ENERGY STAR score went from 89 in 2017 to 72 in 2023 (-17 points); its best year on file was 2017, at 89. Site EUI moved from 91.0 kBtu/ft² (2014) to 66.5 kBtu/ft² (2023), a 27% decrease. Reported emissions went from 7,553 tCO₂e to 3,968 tCO₂e over the same span (down 47%).
What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 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 Jewelers Building's 66.5 kBtu/ft² across 621,390 sq ft works out to about 41.3 billion Btu (12,110 MWh-equivalent) in 2023. Its source EUI of 127.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,991,650 kWh of electricity and 208,494 therms of natural gas for the year.
Which law requires The Jewelers Building to report its energy use?
The Jewelers 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:101790:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
