How has ABC 77W's energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for ABC 77W, covering report years 2022–2024. Its ENERGY STAR score went from 30 in 2022 to 19 in 2024 (-11 points); its best year on file was 2022, at 30. Site EUI moved from 134.1 kBtu/ft² (2022) to 128.7 kBtu/ft² (2024), a 4% decrease. Reported emissions went from 2,937 tCO₂e to 4,860 tCO₂e over the same span (up 65%).
What does an ENERGY STAR score of 19 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 19 means the building performs better than about 19% of its national peers. BuildingCensus bands the score into report-card grades; 19 falls in band D — lowest band (1–54). It sits 56 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. ABC 77W's 128.7 kBtu/ft² across 393,795 sq ft works out to about 50.7 billion Btu (14,853 MWh-equivalent) in 2024. Its source EUI of 290.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 10,256,091 kWh of electricity and 156,790 therms of natural gas for the year.
