How has WGN Studios's energy performance changed over time?
BuildingCensus holds 5 Chicago disclosures for WGN Studios, covering report years 2018–2022. Its ENERGY STAR score went from 8 in 2020 to 1 in 2022 (-7 points); its best year on file was 2020, at 8.

What does an ENERGY STAR score of 1 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: 1 is the bottom of the scale. BuildingCensus bands the score into report-card grades; 1 falls in band D — lowest band (1–54). It sits 74 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. WGN Studios's 414.9 kBtu/ft² across 213,533 sq ft works out to about 88.6 billion Btu (25,965 MWh-equivalent) in 2022. Its source EUI of 986.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,049,725 kWh of electricity and 65,755 therms of natural gas for the year.
Which law requires WGN Studios to report its energy use?
WGN Studios 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:173832:2022). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
