What does an ENERGY STAR score of 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. 333 North Michigan's 76.5 kBtu/ft² across 363,431 sq ft works out to about 27.8 billion Btu (8,148 MWh-equivalent) in 2023. Its source EUI of 127.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,848,100 kWh of electricity and 180,747 therms of natural gas for the year.
Which law requires 333 North Michigan to report its energy use?
333 North Michigan 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:101889:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
