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. 275 Webster Avenue's 86.6 kBtu/ft² across 73,584 sq ft works out to about 6.4 billion Btu (1,868 MWh-equivalent) in 2024. Its source EUI of 115.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 300,020 kWh of electricity, 53,489 therms of natural gas and 3,110 thousand gallons of water for the year.
