How has X079 (OECID: 0200117; BBL: 2031700001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X079 (OECID: 0200117; BBL: 2031700001), covering report years 2022–2024. Its ENERGY STAR score went from 27 in 2022 to 35 in 2024 (+8 points); its best year on file was 2023, at 38. Site EUI moved from 79.2 kBtu/ft² (2022) to 65.0 kBtu/ft² (2024), a 18% decrease. Reported emissions went from 1,077 tCO₂e to 1,096 tCO₂e over the same span (up 2%).
What does an ENERGY STAR score of 35 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 35 means the building performs better than about 35% of its national peers. BuildingCensus bands the score into report-card grades; 35 falls in band D — lowest band (1–54). It sits 40 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. X079 (OECID: 0200117; BBL: 2031700001)'s 65.0 kBtu/ft² across 182,400 sq ft works out to about 11.9 billion Btu (3,475 MWh-equivalent) in 2024. Its source EUI of 125.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,779,468 kWh of electricity, 15,082 therms of natural gas and 900 thousand gallons of water for the year.
Which law requires X079 (OECID: 0200117; BBL: 2031700001) to report its energy use?
