K781 (OECID: 0301800; BBL: 3055870038)'s ENERGY STAR score of 81 compares with an average of 64 across the 2,052 that report a score; it scores higher than 68% of them and lower than 30%. Its site EUI of 76.6 kBtu/ft² is about 25% 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 27,660 sq ft, it is about 73% below the average floor area of 101,338 sq ft for those buildings. Its 1956 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 K781 (OECID: 0301800; BBL: 3055870038)'s energy performance changed over time?
BuildingCensus holds 2 New York City disclosures for K781 (OECID: 0301800; BBL: 3055870038), covering report years 2022–2023. Its ENERGY STAR score went from 87 in 2022 to 81 in 2023 (-6 points); its best year on file was 2022, at 87. Site EUI moved from 74.1 kBtu/ft² (2022) to 76.6 kBtu/ft² (2023), an 3% increase. Reported emissions went from 124 tCO₂e to 135 tCO₂e over the same span (up 8%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 falls in band B — above median (70–84). 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. K781 (OECID: 0301800; BBL: 3055870038)'s 76.6 kBtu/ft² across 27,660 sq ft works out to about 2.1 billion Btu (621 MWh-equivalent) in 2023. Its source EUI of 105.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 115,793 kWh of electricity, 17,235 therms of natural gas and 0 thousand gallons of water for the year.
Which law requires K781 (OECID: 0301800; BBL: 3055870038) to report its energy use?
