X018 (OECID: 0201375; BBL: 2023240008)'s ENERGY STAR score of 99 compares with an average of 64 across the 2,052 that report a score; it scores higher than 96% of them and lower than 3%. Its site EUI of 41.2 kBtu/ft² is about 33% 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 2.5 kgCO₂e/ft² is about half of the group average of 4.8 kgCO₂e/ft².
At 86,320 sq ft, it is about 15% below the average floor area of 101,338 sq ft for those buildings. Its 1952 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 X018 (OECID: 0201375; BBL: 2023240008)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for X018 (OECID: 0201375; BBL: 2023240008), covering report years 2022–2024. Its ENERGY STAR score went from 79 in 2022 to 99 in 2024 (+20 points). Site EUI moved from 69.6 kBtu/ft² (2022) to 41.2 kBtu/ft² (2024), a 41% decrease. Reported emissions went from 378 tCO₂e to 212 tCO₂e over the same span (down 44%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. X018 (OECID: 0201375; BBL: 2023240008)'s 41.2 kBtu/ft² across 86,320 sq ft works out to about 3.6 billion Btu (1,042 MWh-equivalent) in 2024. Its source EUI of 51.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 112,416 kWh of electricity, 31,623 therms of natural gas and 0 thousand gallons of water for the year.
Which law requires X018 (OECID: 0201375; BBL: 2023240008) to report its energy use?
