How does X024 (OECID: 0200059; BBL: 2059170140) 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. X024 (OECID: 0200059; BBL: 2059170140)'s ENERGY STAR score of 93 compares with an average of 64 across the 2,052 that report a score; it scores higher than 88% of them and lower than 11%. Its site EUI of 48.4 kBtu/ft² is about 21% below the average of 61.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.8 kgCO₂e/ft² is about 42% below the group average of 4.8 kgCO₂e/ft².
At 115,325 sq ft, it is about 14% above the average floor area of 101,338 sq ft for those buildings. Its 1953 construction date is close to 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 X024 (OECID: 0200059; BBL: 2059170140)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X024 (OECID: 0200059; BBL: 2059170140), covering report years 2022–2024. Its ENERGY STAR score went from 77 in 2022 to 93 in 2024 (+16 points). Site EUI moved from 64.6 kBtu/ft² (2022) to 48.4 kBtu/ft² (2024), a 25% decrease. Reported emissions went from 444 tCO₂e to 320 tCO₂e over the same span (down 28%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. X024 (OECID: 0200059; BBL: 2059170140)'s 48.4 kBtu/ft² across 115,325 sq ft works out to about 5.6 billion Btu (1,636 MWh-equivalent) in 2024. Its source EUI of 62.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 226,605 kWh of electricity, 43,531 therms of natural gas and 2,774 thousand gallons of water for the year.
Which law requires X024 (OECID: 0200059; BBL: 2059170140) to report its energy use?
