Its ENERGY STAR score went from 20 in 2016 to 90 in 2023 (+70 points); its best year on file was 2022, at 93. Site EUI moved from 88.5 kBtu/ft² (2016) to 58.7 kBtu/ft² (2023), a 34% decrease.

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. Blackstone Court LLC's 58.7 kBtu/ft² across 52,272 sq ft works out to about 3.1 billion Btu (899 MWh-equivalent) in 2023. Its source EUI of 74.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 112,967 kWh of electricity and 26,820 therms of natural gas for the year.
Which law requires Blackstone Court LLC to report its energy use?
Blackstone Court 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:260029:2023).
