What does an ENERGY STAR score of 32 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 32 means the building performs better than about 32% of its national peers. BuildingCensus bands the score into report-card grades; 32 falls in band D — lowest band (1–54). It sits 43 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. 808-12 Junior Terrace LLC's 64.3 kBtu/ft² across 76,690 sq ft works out to about 4.9 billion Btu (1,445 MWh-equivalent) in 2023. Its source EUI of 142.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 963,536 kWh of electricity and 16,408 therms of natural gas for the year.

Which law requires 808-12 Junior Terrace LLC to report its energy use?
