What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. 2337-2349 Green Street SE's 60.1 kBtu/ft² across 106,336 sq ft works out to about 6.4 billion Btu (1,873 MWh-equivalent) in 2024. Its source EUI of 97.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 619,269 kWh of electricity, 42,813 therms of natural gas and 2,780 thousand gallons of water for the year.

Which law requires 2337-2349 Green Street SE to report its energy use?
