How has 325 West End Ave.'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for 325 West End Ave., covering report years 2022–2024. Its ENERGY STAR score was 95 in both 2022 and 2024.

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 falls in band A — high performer (85–100). 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. 325 West End Ave.'s 50.0 kBtu/ft² across 171,646 sq ft works out to about 8.6 billion Btu (2,515 MWh-equivalent) in 2024. Its source EUI of 74.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 636,475 kWh of electricity and 64,156 therms of natural gas for the year.
