How has Gill Park Cooperative's energy performance changed over time?
BuildingCensus holds 7 Chicago disclosures for Gill Park Cooperative, covering report years 2017–2023. Its ENERGY STAR score went from 82 in 2017 to 98 in 2023 (+16 points); its best year on file was 2021, at 100. Site EUI moved from 92.9 kBtu/ft² (2017) to 67.0 kBtu/ft² (2023), a 28% decrease. Reported emissions went from 1,565 tCO₂e to 1,007 tCO₂e over the same span (down 36%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Gill Park Cooperative's 67.0 kBtu/ft² across 227,000 sq ft works out to about 15.2 billion Btu (4,457 MWh-equivalent) in 2023. Its source EUI of 88.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 673,507 kWh of electricity and 129,104 therms of natural gas for the year.
Which law requires Gill Park Cooperative to report its energy use?
Gill Park Cooperative 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:255148:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
