Its site EUI of 72.0 kBtu/ft² is roughly in line with the average of 70.4 kBtu/ft². Its emissions intensity of 4.8 kgCO₂e/ft² is about 36% below the group average of 7.5 kgCO₂e/ft².
At 224,000 sq ft, it is about half of the average floor area of 488,124 sq ft for those buildings. It was built in 1970, 14 years later 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 1010 W 35Th St's energy performance changed over time?
BuildingCensus holds 6 Chicago disclosures for 1010 W 35Th St, covering report years 2018–2023. Site EUI moved from 22.5 kBtu/ft² (2020) to 72.0 kBtu/ft² (2023), an 220% increase. Reported emissions went from 495 tCO₂e to 1,071 tCO₂e over the same span (up 116%).
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. 1010 W 35Th St's 72.0 kBtu/ft² across 224,000 sq ft works out to about 16.1 billion Btu (4,727 MWh-equivalent) in 2023. Its source EUI of 94.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 722,756 kWh of electricity and 136,719 therms of natural gas for the year.
Which law requires 1010 W 35Th St to report its energy use?
1010 W 35Th 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:160326:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
