How has Gramercy Green's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Gramercy Green, covering report years 2022–2024. Its ENERGY STAR score was 81 in both 2022 and 2024.

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. Gramercy Green's 45.7 kBtu/ft² across 290,634 sq ft works out to about 13.3 billion Btu (3,893 MWh-equivalent) in 2024. Its source EUI of 98.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,476,149 kWh of electricity, 48,465 therms of natural gas and 16,863 thousand gallons of water for the year.
