What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. 363 Erie IL Partners LLC's 43.3 kBtu/ft² across 119,405 sq ft works out to about 5.2 billion Btu (1,515 MWh-equivalent) in 2023. Its source EUI of 95.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 996,627 kWh of electricity and 17,730 therms of natural gas for the year.
Which law requires 363 Erie IL Partners LLC to report its energy use?
363 Erie IL Partners LLC 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.
