What does an ENERGY STAR score of 28 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 28 means the building performs better than about 28% of its national peers. BuildingCensus bands the score into report-card grades; 28 falls in band D — lowest band (1–54). It sits 47 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. 311GE-CHIWB-Downtown's 100.7 kBtu/ft² across 202,602 sq ft works out to about 20.4 billion Btu (5,979 MWh-equivalent) in 2023. Its source EUI of 237.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,477,847 kWh of electricity, 51,255 therms of natural gas and 5,349 thousand gallons of water for the year.
Which law requires 311GE-CHIWB-Downtown to report its energy use?
