BuildingCensus holds 2 New York City disclosures for New West 2: 24-30, 46-50, 52-56: NW2: 24-56 W 111, covering report years 2022–2023. Its ENERGY STAR score went from 81 in 2022 to 71 in 2023 (-10 points); its best year on file was 2022, at 81. Site EUI moved from 69.7 kBtu/ft² (2022) to 72.5 kBtu/ft² (2023), an 4% increase. Reported emissions went from 418 tCO₂e to 460 tCO₂e over the same span (up 10%).

What does an ENERGY STAR score of 71 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 71 means the building performs better than about 71% of its national peers. BuildingCensus bands the score into report-card grades; 71 falls in band B — above median (70–84). It sits 4 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. New West 2: 24-30, 46-50, 52-56: NW2: 24-56 W 111's 72.5 kBtu/ft² across 102,736 sq ft works out to about 7.4 billion Btu (2,183 MWh-equivalent) in 2023. Its source EUI of 95.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 338,869 kWh of electricity and 62,876 therms of natural gas for the year.
