What does an ENERGY STAR score of 52 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 52 means the building performs better than about 52% of its national peers. BuildingCensus bands the score into report-card grades; 52 falls in band D — lowest band (1–54). It sits 23 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. 1130 Connecticut Avenue DDOE's 50.6 kBtu/ft² across 254,104 sq ft works out to about 12.9 billion Btu (3,768 MWh-equivalent) in 2024. Its source EUI of 141.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,768,371 kWh of electricity, 0 therms of natural gas and 2,983 thousand gallons of water for the year.

Which law requires 1130 Connecticut Avenue DDOE to report its energy use?
