How does X036 (OECID: 0200073; BBL: 2038170001) 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. X036 (OECID: 0200073; BBL: 2038170001)'s ENERGY STAR score of 80 compares with an average of 64 across the 2,052 that report a score; it scores higher than 66% of them and lower than 32%. Its site EUI of 68.8 kBtu/ft² is about 12% 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 4.5 kgCO₂e/ft² is roughly in line with the group average of 4.8 kgCO₂e/ft².
At 85,260 sq ft, it is about 16% below the average floor area of 101,338 sq ft for those buildings. It was built in 1901, 52 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 X036 (OECID: 0200073; BBL: 2038170001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X036 (OECID: 0200073; BBL: 2038170001), covering report years 2022–2024. Its ENERGY STAR score went from 67 in 2022 to 80 in 2024 (+13 points). Site EUI moved from 85.4 kBtu/ft² (2022) to 68.8 kBtu/ft² (2024), a 19% decrease. Reported emissions went from 429 tCO₂e to 379 tCO₂e over the same span (down 11%).
What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 falls in band B — above median (70–84). 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. X036 (OECID: 0200073; BBL: 2038170001)'s 68.8 kBtu/ft² across 85,260 sq ft works out to about 5.9 billion Btu (1,719 MWh-equivalent) in 2024. Its source EUI of 94.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 319,445 kWh of electricity, 47,784 therms of natural gas and 0 thousand gallons of water for the year.
Which law requires X036 (OECID: 0200073; BBL: 2038170001) to report its energy use?
X036 (OECID: 0200073; BBL: 2038170001) 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:1634401:2024). Under Local Law 97, buildings over 25,000 sq ft face carbon caps with fines of $268 per metric ton of CO₂e over the limit, phasing in from 2024.
