Its ENERGY STAR score went from 37 in 2022 to 12 in 2024 (-25 points); its best year on file was 2022, at 37. Site EUI moved from 48.3 kBtu/ft² (2022) to 86.3 kBtu/ft² (2024), an 79% increase. Reported emissions went from 187 tCO₂e to 344 tCO₂e over the same span (up 84%).
What does an ENERGY STAR score of 12 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 12 means the building performs better than about 12% of its national peers. BuildingCensus bands the score into report-card grades; 12 falls in band D — lowest band (1–54). It sits 63 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. X448 (OECID: 0201546; BBL: 2032470170)'s 86.3 kBtu/ft² across 48,046 sq ft works out to about 4.1 billion Btu (1,215 MWh-equivalent) in 2024. Its source EUI of 163.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 584,008 kWh of electricity and 21,519 therms of natural gas for the year.
