What does an ENERGY STAR score of 10 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 10 means the building performs better than about 10% of its national peers. BuildingCensus bands the score into report-card grades; 10 falls in band D — lowest band (1–54). It sits 65 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. 820 N Orleans Street's 119.7 kBtu/ft² across 118,000 sq ft works out to about 14.1 billion Btu (4,140 MWh-equivalent) in 2023. Its source EUI of 335.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,141,022 kWh of electricity for the year.
