M844 (OECID: 0100199; BBL: 1009550001)'s ENERGY STAR score of 90 compares with an average of 64 across the 2,052 that report a score; it scores higher than 83% of them and lower than 15%. Its site EUI of 55.0 kBtu/ft² is about 10% below 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 4.7 kgCO₂e/ft² is roughly in line with the group average of 4.8 kgCO₂e/ft².
At 68,480 sq ft, it is about 32% below the average floor area of 101,338 sq ft for those buildings. It was built in 1931, 22 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 M844 (OECID: 0100199; BBL: 1009550001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M844 (OECID: 0100199; BBL: 1009550001), covering report years 2022–2024. Its ENERGY STAR score went from 81 in 2022 to 90 in 2024 (+9 points); its best year on file was 2023, at 90. Site EUI moved from 73.9 kBtu/ft² (2022) to 55.0 kBtu/ft² (2024), a 26% decrease. Reported emissions went from 364 tCO₂e to 319 tCO₂e over the same span (down 12%).
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 falls in band A — high performer (85–100). 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. M844 (OECID: 0100199; BBL: 1009550001)'s 55.0 kBtu/ft² across 68,480 sq ft works out to about 3.8 billion Btu (1,104 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 413,644 kWh of electricity for the year.
Which law requires M844 (OECID: 0100199; BBL: 1009550001) to report its energy use?
