What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 points below 75, the threshold for ENERGY STAR certification. In New York City, 43% 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. 440 Washington's 49.8 kBtu/ft² across 51,979 sq ft works out to about 2.6 billion Btu (759 MWh-equivalent) in 2024. Its source EUI of 106.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 474,154 kWh of electricity, 9,719 therms of natural gas and 1,439 thousand gallons of water for the year.

Which law requires 440 Washington to report its energy use?
