M165 (OECID: 0100143; BBL: 1018800013)'s ENERGY STAR score of 85 compares with an average of 64 across the 2,052 that report a score; it scores higher than 75% of them and lower than 23%. Its site EUI of 48.1 kBtu/ft² is about 22% 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 3.4 kgCO₂e/ft² is about 28% below the group average of 4.8 kgCO₂e/ft².
At 144,125 sq ft, it is about 42% above the average floor area of 101,338 sq ft for those buildings. It was built in 1925, 28 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 M165 (OECID: 0100143; BBL: 1018800013)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for M165 (OECID: 0100143; BBL: 1018800013), covering report years 2022–2024. Its ENERGY STAR score went from 73 in 2022 to 85 in 2024 (+12 points). Site EUI moved from 66.0 kBtu/ft² (2022) to 48.1 kBtu/ft² (2024), a 27% decrease. Reported emissions went from 573 tCO₂e to 496 tCO₂e over the same span (down 13%).
What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. M165 (OECID: 0100143; BBL: 1018800013)'s 48.1 kBtu/ft² across 144,125 sq ft works out to about 6.9 billion Btu (2,032 MWh-equivalent) in 2024. Its source EUI of 75.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 602,486 kWh of electricity and 48,807 therms of natural gas for the year.
Which law requires M165 (OECID: 0100143; BBL: 1018800013) to report its energy use?
