Its ENERGY STAR score went from 59 in 2016 to 34 in 2023 (-25 points); its best year on file was 2017, at 69. Site EUI moved from 102.9 kBtu/ft² (2016) to 107.7 kBtu/ft² (2023), an 5% increase. Reported emissions went from 450 tCO₂e to 444 tCO₂e over the same span (down 1%).

What does an ENERGY STAR score of 34 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 34 means the building performs better than about 34% of its national peers. BuildingCensus bands the score into report-card grades; 34 falls in band D — lowest band (1–54). It sits 41 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. 2339 N. Geneva's 107.7 kBtu/ft² across 64,979 sq ft works out to about 7 billion Btu (2,051 MWh-equivalent) in 2023. Its source EUI of 135.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 243,108 kWh of electricity and 61,677 therms of natural gas for the year.

Which law requires 2339 N. Geneva to report its energy use?

2339 N. Geneva 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:175711:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
