What does an ENERGY STAR score of 49 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 49 means the building performs better than about 49% of its national peers. BuildingCensus bands the score into report-card grades; 49 falls in band D — lowest band (1–54). It sits 26 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. Club Ouarters East Wacker Drive's 110.8 kBtu/ft² across 178,845 sq ft works out to about 19.8 billion Btu (5,808 MWh-equivalent) in 2023. Its source EUI of 181.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,937,639 kWh of electricity and 131,970 therms of natural gas for the year.
