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. Renee Granville-Grossman Residential Commons's 116.2 kBtu/ft² across 338,679 sq ft works out to about 39.4 billion Btu (11,534 MWh-equivalent) in 2023. Its source EUI of 186.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,273,226 kWh of electricity and 8,634 therms of natural gas for the year.

Which law requires Renee Granville-Grossman Residential Commons to report its energy use?
