How has University Park CA's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for University Park CA, covering report years 2015–2023. Its ENERGY STAR score went from 58 in 2015 to 50 in 2023 (-8 points); its best year on file was 2021, at 89. Site EUI moved from 109.1 kBtu/ft² (2015) to 102.5 kBtu/ft² (2023), a 6% decrease. Reported emissions went from 3,835 tCO₂e to 3,397 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 50 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 50 means the building performs better than about 50% of its national peers. BuildingCensus bands the score into report-card grades; 50 falls in band D — lowest band (1–54). It sits 25 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. University Park CA's 102.5 kBtu/ft² across 538,980 sq ft works out to about 55.2 billion Btu (16,191 MWh-equivalent) in 2023. Its source EUI of 124.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,560,501 kWh of electricity and 499,210 therms of natural gas for the year.
Which law requires University Park CA to report its energy use?
University Park CA 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:222943:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
