How has Cooper Gramercy's energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for Cooper Gramercy, covering report years 2022–2023. Its ENERGY STAR score was 100 in both 2022 and 2023. Site EUI moved from 19.1 kBtu/ft² (2022) to 18.1 kBtu/ft² (2023), a 5% decrease. Reported emissions went from 310 tCO₂e to 368 tCO₂e over the same span (up 19%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Cooper Gramercy's 18.1 kBtu/ft² across 200,299 sq ft works out to about 3.6 billion Btu (1,063 MWh-equivalent) in 2023. Its source EUI of 46.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 926,682 kWh of electricity, 4,598 therms of natural gas and 8,990 thousand gallons of water for the year.
