How has East Park Tower's energy performance changed over time?
BuildingCensus holds 8 Chicago disclosures for East Park Tower, covering report years 2016–2023. Its ENERGY STAR score went from 75 in 2016 to 85 in 2023 (+10 points); its best year on file was 2018, at 89. Site EUI moved from 88.1 kBtu/ft² (2016) to 65.5 kBtu/ft² (2023), a 26% decrease. Reported emissions went from 775 tCO₂e to 622 tCO₂e over the same span (down 20%).
What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. East Park Tower's 65.5 kBtu/ft² across 137,394 sq ft works out to about 9 billion Btu (2,637 MWh-equivalent) in 2023. Its source EUI of 89.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 484,493 kWh of electricity and 73,453 therms of natural gas for the year.
Which law requires East Park Tower to report its energy use?
East Park Tower 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:157346:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
