How has X435 (OECID: 0200226; BBL: 2030590001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X435 (OECID: 0200226; BBL: 2030590001), covering report years 2022–2024. Its ENERGY STAR score went from 85 in 2022 to 86 in 2024 (+1 points); its best year on file was 2023, at 87. Site EUI moved from 68.3 kBtu/ft² (2022) to 66.9 kBtu/ft² (2024), a 2% decrease. Reported emissions went from 1,565 tCO₂e to 1,670 tCO₂e over the same span (up 7%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. X435 (OECID: 0200226; BBL: 2030590001)'s 66.9 kBtu/ft² across 382,925 sq ft works out to about 25.6 billion Btu (7,508 MWh-equivalent) in 2024. Its source EUI of 93.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,464,105 kWh of electricity and 206,196 therms of natural gas for the year.
Which law requires X435 (OECID: 0200226; BBL: 2030590001) to report its energy use?
