The latest disclosures cover 2,301 K-12 school buildings in New York City, out of 48,310 buildings citywide. K136, K939 (OECID: 0300143; BBL: 3007130020)'s ENERGY STAR score of 97 compares with an average of 64 across the 2,052 that report a score; it scores higher than 93% of them and lower than 5%. Its site EUI of 45.7 kBtu/ft² is about 25% 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 3.5 kgCO₂e/ft² is about 26% below the group average of 4.8 kgCO₂e/ft².

At 144,000 sq ft, it is about 42% above the average floor area of 101,338 sq ft for those buildings. It was built in 1901, 52 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 K136, K939 (OECID: 0300143; BBL: 3007130020)'s energy performance changed over time?

BuildingCensus holds 3 New York City disclosures for K136, K939 (OECID: 0300143; BBL: 3007130020), covering report years 2022–2024. Its ENERGY STAR score went from 59 in 2022 to 97 in 2024 (+38 points). Site EUI moved from 88.8 kBtu/ft² (2022) to 45.7 kBtu/ft² (2024), a 49% decrease. Reported emissions went from 968 tCO₂e to 509 tCO₂e over the same span (down 47%).

What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. K136, K939 (OECID: 0300143; BBL: 3007130020)'s 45.7 kBtu/ft² across 144,000 sq ft works out to about 6.6 billion Btu (1,929 MWh-equivalent) in 2024. Its source EUI of 56.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 229,160 kWh of electricity, 5,144 therms of natural gas and 493 thousand gallons of water for the year.

Which law requires K136, K939 (OECID: 0300143; BBL: 3007130020) to report its energy use?
