How does Q184 (OECID: 0400163; BBL: 4057560001) 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. Q184 (OECID: 0400163; BBL: 4057560001)'s ENERGY STAR score of 86 compares with an average of 64 across the 2,052 that report a score; it scores higher than 77% of them and lower than 22%. Its site EUI of 46.3 kBtu/ft² is about 24% 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 3.3 kgCO₂e/ft² is about 31% below the group average of 4.8 kgCO₂e/ft².
At 68,400 sq ft, it is about 33% below the average floor area of 101,338 sq ft for those buildings. Its 1951 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 Q184 (OECID: 0400163; BBL: 4057560001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Q184 (OECID: 0400163; BBL: 4057560001), covering report years 2022–2024. Its ENERGY STAR score went from 84 in 2022 to 86 in 2024 (+2 points); its best year on file was 2023, at 87. Site EUI moved from 54.1 kBtu/ft² (2022) to 46.3 kBtu/ft² (2024), a 14% decrease. Reported emissions went from 224 tCO₂e to 227 tCO₂e over the same span (up 1%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Q184 (OECID: 0400163; BBL: 4057560001)'s 46.3 kBtu/ft² across 68,400 sq ft works out to about 3.2 billion Btu (928 MWh-equivalent) in 2024. Its source EUI of 72.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 276,266 kWh of electricity and 22,238 therms of natural gas for the year.
Which law requires Q184 (OECID: 0400163; BBL: 4057560001) to report its energy use?
