How does K223 (OECID: 0300228; BBL: 3053620021) 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. K223 (OECID: 0300228; BBL: 3053620021)'s ENERGY STAR score of 69 compares with an average of 64 across the 2,052 that report a score; it scores higher than 49% of them and lower than 49%. Its site EUI of 70.9 kBtu/ft² is about 16% 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 roughly in line with the group average of 4.8 kgCO₂e/ft².
At 145,200 sq ft, it is about 43% 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 K223 (OECID: 0300228; BBL: 3053620021)'s energy performance changed over time?
BuildingCensus holds 3 New York City disclosures for K223 (OECID: 0300228; BBL: 3053620021), covering report years 2022–2024. Its ENERGY STAR score went from 57 in 2022 to 69 in 2024 (+12 points). Site EUI moved from 92.0 kBtu/ft² (2022) to 70.9 kBtu/ft² (2024), a 23% decrease. Reported emissions went from 826 tCO₂e to 766 tCO₂e over the same span (down 7%).
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 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. K223 (OECID: 0300228; BBL: 3053620021)'s 70.9 kBtu/ft² across 145,200 sq ft works out to about 10.3 billion Btu (3,017 MWh-equivalent) in 2024. Its source EUI of 109.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 864,088 kWh of electricity, 56,215 therms of natural gas and 293 thousand gallons of water for the year.
