What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. 1027 Westchester Avenue LLC's 52.3 kBtu/ft² across 25,200 sq ft works out to about 1.3 billion Btu (386 MWh-equivalent) in 2023. Its source EUI of 138.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 351,816 kWh of electricity and 1,183 therms of natural gas for the year.
