How has State Tower CA's energy performance changed over time?

BuildingCensus holds 8 Chicago disclosures for State Tower CA, covering report years 2016–2023. Its ENERGY STAR score went from 45 in 2016 to 49 in 2023 (+4 points).

What does an ENERGY STAR score of 49 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 49 means the building performs better than about 49% of its national peers. BuildingCensus bands the score into report-card grades; 49 falls in band D — lowest band (1–54). It sits 26 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. State Tower CA's 92.2 kBtu/ft² across 144,671 sq ft works out to about 13.3 billion Btu (3,909 MWh-equivalent) in 2023. Its source EUI of 134.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 922,469 kWh of electricity and 101,939 therms of natural gas for the year.

Which law requires State Tower CA to report its energy use?

State Tower CA 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:113764:2023).
