What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 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. Wadsworth House Condominium's 33.6 kBtu/ft² across 58,232 sq ft works out to about 2 billion Btu (573 MWh-equivalent) in 2024. Its source EUI of 93.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 572,598 kWh of electricity, 0 therms of natural gas and 1,324 thousand gallons of water for the year.
