How does Q002 (OECID: 0400009; BBL: 4009710001) 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. Q002 (OECID: 0400009; BBL: 4009710001)'s ENERGY STAR score of 78 compares with an average of 64 across the 2,052 that report a score; it scores higher than 63% of them and lower than 36%. Its site EUI of 56.4 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 4.2 kgCO₂e/ft² is about 12% below the group average of 4.8 kgCO₂e/ft².

At 74,480 sq ft, it is about 27% below the average floor area of 101,338 sq ft for those buildings. Its 1953 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 Q002 (OECID: 0400009; BBL: 4009710001)'s energy performance changed over time?

BuildingCensus holds 3 New York City disclosures for Q002 (OECID: 0400009; BBL: 4009710001), covering report years 2022–2024. Its ENERGY STAR score went from 49 in 2022 to 78 in 2024 (+29 points). Site EUI moved from 91.9 kBtu/ft² (2022) to 56.4 kBtu/ft² (2024), a 39% decrease. Reported emissions went from 432 tCO₂e to 436 tCO₂e over the same span (up 1%).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. Q002 (OECID: 0400009; BBL: 4009710001)'s 56.4 kBtu/ft² across 74,480 sq ft works out to about 4.2 billion Btu (1,231 MWh-equivalent) in 2024. Its source EUI of 89.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 535,363 kWh of electricity, 33,761 therms of natural gas and 0 thousand gallons of water for the year.

Which law requires Q002 (OECID: 0400009; BBL: 4009710001) to report its energy use?

Q002 (OECID: 0400009; BBL: 4009710001) 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:1633401:2024). 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.
