M104 (OECID: 0100098; BBL: 1009260001)'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 34.8 kBtu/ft² is about 43% 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 3.1 kgCO₂e/ft² is about 35% below the group average of 4.8 kgCO₂e/ft².
At 146,575 sq ft, it is about 45% above the average floor area of 101,338 sq ft for those buildings. Its 1954 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 M104 (OECID: 0100098; BBL: 1009260001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M104 (OECID: 0100098; BBL: 1009260001), covering report years 2022–2024. Its ENERGY STAR score went from 89 in 2022 to 90 in 2024 (+1 points). Site EUI moved from 40.8 kBtu/ft² (2022) to 34.8 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 439 tCO₂e to 455 tCO₂e over the same span (up 4%).
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. M104 (OECID: 0100098; BBL: 1009260001)'s 34.8 kBtu/ft² across 146,575 sq ft works out to about 5.1 billion Btu (1,495 MWh-equivalent) in 2024. Its source EUI of 67.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 700,101 kWh of electricity and 159 therms of natural gas for the year.
Which law requires M104 (OECID: 0100098; BBL: 1009260001) to report its energy use?
