What does an ENERGY STAR score of 44 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 44 means the building performs better than about 44% of its national peers. BuildingCensus bands the score into report-card grades; 44 falls in band D — lowest band (1–54). It sits 31 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. The Silver Tower Chicago Condominium Association's 83.2 kBtu/ft² across 285,627 sq ft works out to about 23.8 billion Btu (6,965 MWh-equivalent) in 2023. Its source EUI of 147.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,853,625 kWh of electricity and 140,301 therms of natural gas for the year.

Which law requires The Silver Tower Chicago Condominium Association to report its energy use?
