What does an ENERGY STAR score of 47 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 47 means the building performs better than about 47% of its national peers. BuildingCensus bands the score into report-card grades; 47 falls in band D — lowest band (1–54). It sits 28 points below 75, the threshold for ENERGY STAR certification. In Washington, DC, 47% 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. Parc Riverside-Toll Brothers's 46.6 kBtu/ft² across 271,944 sq ft works out to about 12.7 billion Btu (3,714 MWh-equivalent) in 2020. Its source EUI of 124.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,444,317 kWh of electricity, 9,336 therms of natural gas and 7,971 thousand gallons of water for the year.

Which law requires Parc Riverside-Toll Brothers to report its energy use?
