How has State Lake LLC's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for State Lake LLC, covering report years 2015–2023. Its ENERGY STAR score went from 6 in 2015 to 3 in 2023 (-3 points); its best year on file was 2020, at 12. Site EUI moved from 128.9 kBtu/ft² (2015) to 162.8 kBtu/ft² (2023), an 26% increase. Reported emissions went from 1,662 tCO₂e to 1,208 tCO₂e over the same span (down 27%).
What does an ENERGY STAR score of 3 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 3 means the building performs better than about 3% of its national peers. BuildingCensus bands the score into report-card grades; 3 falls in band D — lowest band (1–54). It sits 72 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 Lake LLC's 162.8 kBtu/ft² across 53,053 sq ft works out to about 8.6 billion Btu (2,531 MWh-equivalent) in 2023. Its source EUI of 455.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,530,547 kWh of electricity for the year.
Which law requires State Lake LLC to report its energy use?
State Lake LLC 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:250140:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
