How does X019 (OECID: 0200054; BBL: 2033860001) 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. X019 (OECID: 0200054; BBL: 2033860001)'s ENERGY STAR score of 50 compares with an average of 64 across the 2,052 that report a score; it scores higher than 27% of them and lower than 72%. Its site EUI of 60.9 kBtu/ft² is roughly in line with 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 4.5 kgCO₂e/ft² is roughly in line with the group average of 4.8 kgCO₂e/ft².
At 98,800 sq ft, it is roughly in line with the average floor area of 101,338 sq ft for those buildings. It was built in 1925, 28 years earlier 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 X019 (OECID: 0200054; BBL: 2033860001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X019 (OECID: 0200054; BBL: 2033860001), covering report years 2022–2024. Its ENERGY STAR score went from 47 in 2022 to 50 in 2024 (+3 points). Site EUI moved from 71.9 kBtu/ft² (2022) to 60.9 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 450 tCO₂e to 448 tCO₂e over the same span (down 1%).
What does an ENERGY STAR score of 50 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 50 means the building performs better than about 50% of its national peers. BuildingCensus bands the score into report-card grades; 50 falls in band D — lowest band (1–54). It sits 25 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. X019 (OECID: 0200054; BBL: 2033860001)'s 60.9 kBtu/ft² across 98,800 sq ft works out to about 6 billion Btu (1,763 MWh-equivalent) in 2024. Its source EUI of 97.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 557,581 kWh of electricity, 36,342 therms of natural gas and 614 thousand gallons of water for the year.
Which law requires X019 (OECID: 0200054; BBL: 2033860001) to report its energy use?
X019 (OECID: 0200054; BBL: 2033860001) reports under Local Law 84 (LL84), the legal basis of New York City's Energy and Water Data Disclosure program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record nyc:1633062:2024).
