How has X465 (OECID: 0201410; BBL: 2029230018)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X465 (OECID: 0201410; BBL: 2029230018), covering report years 2022–2024. Its ENERGY STAR score went from 1 in 2022 to 5 in 2024 (+4 points). Site EUI moved from 205.4 kBtu/ft² (2022) to 126.9 kBtu/ft² (2024), a 38% decrease. Reported emissions went from 1,061 tCO₂e to 873 tCO₂e over the same span (down 18%).
What does an ENERGY STAR score of 5 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 5 means the building performs better than about 5% of its national peers. BuildingCensus bands the score into report-card grades; 5 falls in band D — lowest band (1–54). It sits 70 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. X465 (OECID: 0201410; BBL: 2029230018)'s 126.9 kBtu/ft² across 78,910 sq ft works out to about 10 billion Btu (2,935 MWh-equivalent) in 2024. Its source EUI of 255.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,614,247 kWh of electricity, 45,095 therms of natural gas and 804 thousand gallons of water for the year.
Which law requires X465 (OECID: 0201410; BBL: 2029230018) to report its energy use?
