Its ENERGY STAR score went from 100 in 2015 to 72 in 2023 (-28 points); its best year on file was 2015, at 100. Site EUI moved from 24.4 kBtu/ft² (2015) to 57.7 kBtu/ft² (2023), an 136% increase. Reported emissions went from 401 tCO₂e to 349 tCO₂e over the same span (down 13%).
What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 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. Adlake Limited Partnership's 57.7 kBtu/ft² across 81,000 sq ft works out to about 4.7 billion Btu (1,370 MWh-equivalent) in 2023. Its source EUI of 85.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 341,678 kWh of electricity, 35,067 therms of natural gas and 419 thousand gallons of water for the year.
Which law requires Adlake Limited Partnership to report its energy use?
Adlake Limited Partnership 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:173597:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
