What does an ENERGY STAR score of 39 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 39 means the building performs better than about 39% of its national peers. BuildingCensus bands the score into report-card grades; 39 falls in band D — lowest band (1–54). It sits 36 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. 600 West Chicago & 900 N Kingsbury's 93.6 kBtu/ft² across 2,376,470 sq ft works out to about 222.4 billion Btu (65,190 MWh-equivalent) in 2023. Its source EUI of 220.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 49,315,420 kWh of electricity, 268,430 therms of natural gas and 18,155 thousand gallons of water for the year.
