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. 73rd St Apts., LLC's 85.0 kBtu/ft² across 106,000 sq ft works out to about 9 billion Btu (2,641 MWh-equivalent) in 2023. Its source EUI of 116.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 486,756 kWh of electricity and 73,527 therms of natural gas for the year.
