The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. M121 (OECID: 0100111; BBL: 1016520016)'s ENERGY STAR score of 70 compares with an average of 64 across the 2,052 that report a score; it scores higher than 51% of them and lower than 48%. Its site EUI of 67.6 kBtu/ft² is about 10% 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 85,280 sq ft, it is about 16% below the average floor area of 101,338 sq ft for those buildings. It was built in 1923, 30 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 M121 (OECID: 0100111; BBL: 1016520016)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M121 (OECID: 0100111; BBL: 1016520016), covering report years 2022–2024. Its ENERGY STAR score went from 45 in 2022 to 70 in 2024 (+25 points). Site EUI moved from 99.0 kBtu/ft² (2022) to 67.6 kBtu/ft² (2024), a 32% decrease. Reported emissions went from 514 tCO₂e to 419 tCO₂e over the same span (down 18%).
What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 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. M121 (OECID: 0100111; BBL: 1016520016)'s 67.6 kBtu/ft² across 85,280 sq ft works out to about 5.8 billion Btu (1,690 MWh-equivalent) in 2024. Its source EUI of 108.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 535,662 kWh of electricity and 39,358 therms of natural gas for the year.
Which law requires M121 (OECID: 0100111; BBL: 1016520016) to report its energy use?
M121 (OECID: 0100111; BBL: 1016520016) 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:1634369:2024). 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.
