What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 1109 - Royal Sonesta - Washington DC 2121 P Street, NW - SVC's 87.4 kBtu/ft² across 251,878 sq ft works out to about 22 billion Btu (6,452 MWh-equivalent) in 2024.
