What does an ENERGY STAR score of 16 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 16 means the building performs better than about 16% of its national peers. BuildingCensus bands the score into report-card grades; 16 falls in band D — lowest band (1–54). It sits 59 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. 230-Senior Suites-Central Station's 75.0 kBtu/ft² across 71,586 sq ft works out to about 5.4 billion Btu (1,573 MWh-equivalent) in 2023.

The disclosure also reports 497,847 kWh of electricity, 36,721 therms of natural gas and 5,437 thousand gallons of water for the year.
