How does 40 Flatbush Avenue compare with other K-12 school buildings in New York City?

Its site EUI of 1.0 kBtu/ft² is about 98% 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 0.1 kgCO₂e/ft² is about 98% below the group average of 4.8 kgCO₂e/ft².
At 318,408 sq ft, it is about 214% above the average floor area of 101,338 sq ft for those buildings. It was built in 1915, 38 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.
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 40 Flatbush Avenue's 1.0 kBtu/ft² across 318,408 sq ft works out to about 0.3 billion Btu (93 MWh-equivalent) in 2023. Its source EUI of 1.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is different. The disclosure also reports 3,114 therms of natural gas for the year.
Which law requires 40 Flatbush Avenue to report its energy use?
