What does an ENERGY STAR score of 1 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: 1 is the bottom of the scale. BuildingCensus bands the score into report-card grades; 1 falls in band D — lowest band (1–54). It sits 74 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. Nostrand Gardens Co-op 2430's 112.5 kBtu/ft² across 119,662 sq ft works out to about 13.5 billion Btu (3,945 MWh-equivalent) in 2022. Its source EUI of 192.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,497,640 kWh of electricity and 5,625 thousand gallons of water for the year.
