Its ENERGY STAR score went from 83 in 2023 to 81 in 2024 (-2 points); its best year on file was 2023, at 83. Site EUI moved from 69.7 kBtu/ft² (2022) to 64.8 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 745 tCO₂e to 763 tCO₂e over the same span (up 2%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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. 257 W 39's 64.8 kBtu/ft² across 177,975 sq ft works out to about 11.5 billion Btu (3,380 MWh-equivalent) in 2024. Its source EUI of 91.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 711,175 kWh of electricity and 91,096 therms of natural gas for the year.
