What does an ENERGY STAR score of 29 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 29 means the building performs better than about 29% of its national peers. BuildingCensus bands the score into report-card grades; 29 falls in band D — lowest band (1–54). It sits 46 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. Buchanan School Condominium's 55.5 kBtu/ft² across 47,042 sq ft works out to about 2.6 billion Btu (765 MWh-equivalent) in 2024. Its source EUI of 110.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 411,285 kWh of electricity, 12,086 therms of natural gas and 676 thousand gallons of water for the year.
