How has 329 East 63rd Street's energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for 329 East 63rd Street, covering report years 2022–2023. Its ENERGY STAR score was 93 in both 2022 and 2023.

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. 329 East 63rd Street's 71.3 kBtu/ft² across 55,776 sq ft works out to about 4 billion Btu (1,165 MWh-equivalent) in 2023. Its source EUI of 100.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 235,473 kWh of electricity, 31,746 therms of natural gas and 2,702 thousand gallons of water for the year.
