How has K440 (OECID: 0300364; BBL: 3011870001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K440 (OECID: 0300364; BBL: 3011870001), covering report years 2022–2024. Its ENERGY STAR score went from 56 in 2022 to 55 in 2024 (-1 points); its best year on file was 2022, at 56. Site EUI moved from 91.7 kBtu/ft² (2022) to 90.3 kBtu/ft² (2024), a 2% decrease. Reported emissions went from 1,875 tCO₂e to 2,001 tCO₂e over the same span (up 7%).
What does an ENERGY STAR score of 55 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 55 means the building performs better than about 55% of its national peers. BuildingCensus bands the score into report-card grades; 55 falls in band C — below median (55–69). It sits 20 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. K440 (OECID: 0300364; BBL: 3011870001)'s 90.3 kBtu/ft² across 324,000 sq ft works out to about 29.3 billion Btu (8,574 MWh-equivalent) in 2024. Its source EUI of 130.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,942,579 kWh of electricity, 208,883 therms of natural gas and 74 thousand gallons of water for the year.
