What does an ENERGY STAR score of 15 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 15 means the building performs better than about 15% of its national peers. BuildingCensus bands the score into report-card grades; 15 falls in band D — lowest band (1–54). It sits 60 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. Dearborn Elm Condominium Association's 102.4 kBtu/ft² across 111,011 sq ft works out to about 11.4 billion Btu (3,331 MWh-equivalent) in 2023. Its source EUI of 167.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,114,151 kWh of electricity and 75,650 therms of natural gas for the year.
