K291 (OECID: 0300289; BBL: 3033430001)'s ENERGY STAR score of 84 compares with an average of 64 across the 2,052 that report a score; it scores higher than 74% of them and lower than 25%. Its site EUI of 41.7 kBtu/ft² is about 32% 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 3.7 kgCO₂e/ft² is about 23% below the group average of 4.8 kgCO₂e/ft².
At 214,109 sq ft, it is about twice the average floor area of 101,338 sq ft for those buildings. It was built in 1975, 22 years later 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 K291 (OECID: 0300289; BBL: 3033430001)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K291 (OECID: 0300289; BBL: 3033430001), covering report years 2022–2024. Its ENERGY STAR score went from 69 in 2022 to 84 in 2024 (+15 points); its best year on file was 2023, at 85. Site EUI moved from 65.2 kBtu/ft² (2022) to 41.7 kBtu/ft² (2024), a 36% decrease. Reported emissions went from 910 tCO₂e to 790 tCO₂e over the same span (down 13%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. K291 (OECID: 0300289; BBL: 3033430001)'s 41.7 kBtu/ft² across 214,109 sq ft works out to about 8.9 billion Btu (2,617 MWh-equivalent) in 2024. Its source EUI of 85.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,491,410 kWh of electricity, 38,396 therms of natural gas and 3,230 thousand gallons of water for the year.
Which law requires K291 (OECID: 0300289; BBL: 3033430001) to report its energy use?
