How has X023 (OECID: 0201156; BBL: 2030370079)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X023 (OECID: 0201156; BBL: 2030370079), covering report years 2022–2024. Its ENERGY STAR score went from 19 in 2022 to 57 in 2024 (+38 points). Site EUI moved from 108.9 kBtu/ft² (2022) to 69.9 kBtu/ft² (2024), a 36% decrease. Reported emissions went from 631 tCO₂e to 476 tCO₂e over the same span (down 25%).
What does an ENERGY STAR score of 57 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 57 means the building performs better than about 57% of its national peers. BuildingCensus bands the score into report-card grades; 57 falls in band C — below median (55–69). It sits 18 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. X023 (OECID: 0201156; BBL: 2030370079)'s 69.9 kBtu/ft² across 90,031 sq ft works out to about 6.3 billion Btu (1,844 MWh-equivalent) in 2024. Its source EUI of 117.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 670,574 kWh of electricity, 40,034 therms of natural gas and 761 thousand gallons of water for the year.
Which law requires X023 (OECID: 0201156; BBL: 2030370079) to report its energy use?
