What does an ENERGY STAR score of 59 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 59 means the building performs better than about 59% of its national peers. BuildingCensus bands the score into report-card grades; 59 falls in band C — below median (55–69). It sits 16 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. 28 Liberty's 85.7 kBtu/ft² across 2,200,000 sq ft works out to about 188.5 billion Btu (55,256 MWh-equivalent) in 2024. Its source EUI of 173.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
