How does Q085 (OECID: 0400076; BBL: 4008420031) 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. Q085 (OECID: 0400076; BBL: 4008420031)'s ENERGY STAR score of 66 compares with an average of 64 across the 2,052 that report a score; it scores higher than 44% of them and lower than 54%. Its site EUI of 73.4 kBtu/ft² is about 20% 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 4.9 kgCO₂e/ft² is roughly in line with the group average of 4.8 kgCO₂e/ft².
At 76,080 sq ft, it is about 25% below the average floor area of 101,338 sq ft for those buildings. It was built in 1906, 47 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 Q085 (OECID: 0400076; BBL: 4008420031)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Q085 (OECID: 0400076; BBL: 4008420031), covering report years 2022–2024. Its ENERGY STAR score went from 74 in 2022 to 66 in 2024 (-8 points); its best year on file was 2023, at 76. Site EUI moved from 65.3 kBtu/ft² (2022) to 73.4 kBtu/ft² (2024), an 12% increase. Reported emissions went from 306 tCO₂e to 371 tCO₂e over the same span (up 21%).
What does an ENERGY STAR score of 66 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 66 means the building performs better than about 66% of its national peers. BuildingCensus bands the score into report-card grades; 66 falls in band C — below median (55–69). It sits 9 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. Q085 (OECID: 0400076; BBL: 4008420031)'s 73.4 kBtu/ft² across 76,080 sq ft works out to about 5.6 billion Btu (1,637 MWh-equivalent) in 2024. Its source EUI of 99.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 286,463 kWh of electricity, 39,274 therms of natural gas and 355 thousand gallons of water for the year.
Which law requires Q085 (OECID: 0400076; BBL: 4008420031) to report its energy use?
