What does an ENERGY STAR score of 21 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 21 means the building performs better than about 21% of its national peers. BuildingCensus bands the score into report-card grades; 21 falls in band D — lowest band (1–54). It sits 54 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. Dwight Lofts (dw26)'s 71.6 kBtu/ft² across 196,808 sq ft works out to about 14.1 billion Btu (4,130 MWh-equivalent) in 2023. Its source EUI of 142.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,232,344 kWh of electricity, 64,670 therms of natural gas and 19,087 thousand gallons of water for the year.

Which law requires Dwight Lofts (dw26) to report its energy use?
