How has M477 (OECID: 0101307; BBL: 1000160215)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M477 (OECID: 0101307; BBL: 1000160215), covering report years 2022–2024. Its ENERGY STAR score went from 42 in 2022 to 30 in 2024 (-12 points); its best year on file was 2022, at 42. Site EUI moved from 60.0 kBtu/ft² (2022) to 72.5 kBtu/ft² (2024), an 21% increase. Reported emissions went from 2,279 tCO₂e to 3,267 tCO₂e over the same span (up 43%).
What does an ENERGY STAR score of 30 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 30 means the building performs better than about 30% of its national peers. BuildingCensus bands the score into report-card grades; 30 falls in band D — lowest band (1–54). It sits 45 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. M477 (OECID: 0101307; BBL: 1000160215)'s 72.5 kBtu/ft² across 483,250 sq ft works out to about 35 billion Btu (10,268 MWh-equivalent) in 2024. Its source EUI of 158.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,647,832 kWh of electricity, 123,538 therms of natural gas and 19,755 thousand gallons of water for the year.
