How does K247 (OECID: 0300250; BBL: 3061740036) compare with other K-12 school buildings in New York City?

The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. K247 (OECID: 0300250; BBL: 3061740036)'s ENERGY STAR score of 72 compares with an average of 64 across the 2,052 that report a score; it scores higher than 53% of them and lower than 46%. Its site EUI of 71.5 kBtu/ft² is about 17% 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 5.3 kgCO₂e/ft² is about 10% above the group average of 4.8 kgCO₂e/ft².

At 66,000 sq ft, it is about 35% below the average floor area of 101,338 sq ft for those buildings. It was built in 1936, 17 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 K247 (OECID: 0300250; BBL: 3061740036)'s energy performance changed over time?

BuildingCensus holds 3 New York City disclosures for K247 (OECID: 0300250; BBL: 3061740036), covering report years 2022–2024. Its ENERGY STAR score went from 62 in 2022 to 72 in 2024 (+10 points); its best year on file was 2023, at 73. Site EUI moved from 90.6 kBtu/ft² (2022) to 71.5 kBtu/ft² (2024), a 21% decrease. Reported emissions went from 374 tCO₂e to 350 tCO₂e over the same span (down 7%).

What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 points below 75, the threshold for ENERGY STAR certification. 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. K247 (OECID: 0300250; BBL: 3061740036)'s 71.5 kBtu/ft² across 66,000 sq ft works out to about 4.7 billion Btu (1,383 MWh-equivalent) in 2024. Its source EUI of 112.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 415,940 kWh of electricity, 27,731 therms of natural gas and 70 thousand gallons of water for the year.
