What does an ENERGY STAR score of 55 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 55 means the building performs better than about 55% of its national peers. BuildingCensus bands the score into report-card grades; 55 falls in band C — below median (55–69). It sits 20 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. 600 19th St NW / Dept. of State SA-17A's 73.7 kBtu/ft² across 547,240 sq ft works out to about 40.3 billion Btu (11,820 MWh-equivalent) in 2024. Its source EUI of 169.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,469,957 kWh of electricity, 114,277 therms of natural gas and 7,620 thousand gallons of water for the year.
