How has AMA Plaza's energy performance changed over time?
BuildingCensus holds 10 Chicago disclosures for AMA Plaza, covering report years 2014–2023. Its ENERGY STAR score went from 75 in 2014 to 58 in 2023 (-17 points); its best year on file was 2015, at 83. Site EUI moved from 102.0 kBtu/ft² (2014) to 107.2 kBtu/ft² (2023), an 5% increase. Reported emissions went from 26,440 tCO₂e to 20,895 tCO₂e over the same span (down 21%).
What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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. AMA Plaza's 107.2 kBtu/ft² across 1,870,680 sq ft works out to about 200.5 billion Btu (58,772 MWh-equivalent) in 2023. Its source EUI of 209.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 31,407,496 kWh of electricity, 482,286 therms of natural gas and 19,222 thousand gallons of water for the year.
Which law requires AMA Plaza to report its energy use?
AMA Plaza 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:103816:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
