How does X839 (OECID: 0201321; BBL: 2042900048) compare with other K-12 school buildings in New York City?

The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. X839 (OECID: 0201321; BBL: 2042900048)'s ENERGY STAR score of 51 compares with an average of 64 across the 2,052 that report a score; it scores higher than 28% of them and lower than 72%. Its site EUI of 72.5 kBtu/ft² is about 18% above the average of 61.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.9 kgCO₂e/ft² is about 22% above the group average of 4.8 kgCO₂e/ft².

At 63,330 sq ft, it is about 38% below the average floor area of 101,338 sq ft for those buildings. It was built in 2004, 51 years later than the group's average year built (1954). Across all 24 jurisdictions BuildingCensus covers, the 6,548 K-12 school buildings average an ENERGY STAR score of 64 and a site EUI of 52.7 kBtu/ft².

How has X839 (OECID: 0201321; BBL: 2042900048)'s energy performance changed over time?

BuildingCensus holds 3 New York City disclosures for X839 (OECID: 0201321; BBL: 2042900048), covering report years 2022–2024. Its ENERGY STAR score went from 38 in 2022 to 51 in 2024 (+13 points). Site EUI moved from 77.3 kBtu/ft² (2022) to 72.5 kBtu/ft² (2024), a 6% decrease. Reported emissions went from 345 tCO₂e to 372 tCO₂e over the same span (up 8%).

What does an ENERGY STAR score of 51 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 51 means the building performs better than about 51% of its national peers. BuildingCensus bands the score into report-card grades; 51 falls in band D — lowest band (1–54). It sits 24 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. X839 (OECID: 0201321; BBL: 2042900048)'s 72.5 kBtu/ft² across 63,330 sq ft works out to about 4.6 billion Btu (1,346 MWh-equivalent) in 2024. Its source EUI of 133.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 603,291 kWh of electricity, 25,361 therms of natural gas and 275 thousand gallons of water for the year.

Which law requires X839 (OECID: 0201321; BBL: 2042900048) to report its energy use?
