What does an ENERGY STAR score of 21 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 21 means the building performs better than about 21% of its national peers. BuildingCensus bands the score into report-card grades; 21 falls in band D — lowest band (1–54). It sits 54 points below 75, the threshold for ENERGY STAR certification. In New York City, 43% 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. KM 1032 Aldus Street's 123.4 kBtu/ft² across 34,380 sq ft works out to about 4.2 billion Btu (1,243 MWh-equivalent) in 2023. Its source EUI of 161.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
