What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 falls in band A — high performer (85–100). 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. Corcoran Walk Condo's 24.1 kBtu/ft² across 44,932 sq ft works out to about 1.1 billion Btu (317 MWh-equivalent) in 2024. Its source EUI of 67.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 317,164 kWh of electricity, 0 therms of natural gas and 1,033 thousand gallons of water for the year.
