What does an ENERGY STAR score of 16 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 16 means the building performs better than about 16% of its national peers. BuildingCensus bands the score into report-card grades; 16 falls in band D — lowest band (1–54). It sits 59 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. Edgewater Condominium's 77.5 kBtu/ft² across 42,896 sq ft works out to about 3.3 billion Btu (974 MWh-equivalent) in 2024. Its source EUI of 125.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 318,133 kWh of electricity, 22,369 therms of natural gas and 2,033 thousand gallons of water for the year.
