What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. AC-Washington DC's 87.3 kBtu/ft² across 107,151 sq ft works out to about 9.4 billion Btu (2,741 MWh-equivalent) in 2024. Its source EUI of 183.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,639,382 kWh of electricity, 37,566 therms of natural gas and 4,149 thousand gallons of water for the year.
