What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. One Liberty Plaza (149 BROADWAY)'s 64.0 kBtu/ft² across 2,346,193 sq ft works out to about 150.2 billion Btu (44,007 MWh-equivalent) in 2024. Its source EUI of 131.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.
