What does an ENERGY STAR score of 65 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 65 means the building performs better than about 65% of its national peers. BuildingCensus bands the score into report-card grades; 65 falls in band C — below median (55–69). It sits 10 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. 1399 New York Ave NW's 51.9 kBtu/ft² across 143,115 sq ft works out to about 7.4 billion Btu (2,177 MWh-equivalent) in 2024. Its source EUI of 145.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,178,920 kWh of electricity, 0 therms of natural gas and 2,433 thousand gallons of water for the year.
