How does K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036) 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. K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036)'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 66.8 kBtu/ft² is roughly in line with the average of 61.3 kBtu/ft². Its emissions intensity of 5.3 kgCO₂e/ft² is roughly in line with the group average of 4.8 kgCO₂e/ft².
At 180,000 sq ft, it is about 78% above the average floor area of 101,338 sq ft for those buildings. It was built in 1911, 42 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 K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036), covering report years 2022–2024. Its ENERGY STAR score went from 51 in 2022 to 61 in 2024 (+10 points). Site EUI moved from 81.9 kBtu/ft² (2022) to 66.8 kBtu/ft² (2024), a 18% decrease. Reported emissions went from 937 tCO₂e to 947 tCO₂e over the same span (up 1%).
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. K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036)'s 66.8 kBtu/ft² across 180,000 sq ft works out to about 12 billion Btu (3,524 MWh-equivalent) in 2024. Its source EUI of 113.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,326,825 kWh of electricity, 62,193 therms of natural gas and 250 thousand gallons of water for the year.
Which law requires K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036) to report its energy use?
K660 (OECID: 0300381; BBL: 3037040001; 3037040033; 3037040035; 3037040036) 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:1634263:2024). 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.
