The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. Q105 (OECID: 0400889; BBL: 4159740003)'s ENERGY STAR score of 61 compares with an average of 64 across the 2,052 that report a score; it scores higher than 38% of them and lower than 61%. Its site EUI of 59.1 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 103,325 sq ft, it is roughly in line with the average floor area of 101,338 sq ft for those buildings. It was built in 1958, 5 years later 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 Q105 (OECID: 0400889; BBL: 4159740003)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for Q105 (OECID: 0400889; BBL: 4159740003), covering report years 2022–2024. Its ENERGY STAR score went from 39 in 2022 to 61 in 2024 (+22 points). Site EUI moved from 82.4 kBtu/ft² (2022) to 59.1 kBtu/ft² (2024), a 28% decrease. Reported emissions went from 534 tCO₂e to 460 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. Q105 (OECID: 0400889; BBL: 4159740003)'s 59.1 kBtu/ft² across 103,325 sq ft works out to about 6.1 billion Btu (1,790 MWh-equivalent) in 2024. Its source EUI of 99.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 640,160 kWh of electricity, 39,254 therms of natural gas and 1,141 thousand gallons of water for the year.
