Its site EUI of 23.8 kBtu/ft² is about 68% below the average of 74.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.9 kgCO₂e/ft² is about 63% below the group average of 5.2 kgCO₂e/ft².
At 140,000 sq ft, it is about 39% above the average floor area of 100,951 sq ft for those buildings. It was built in 2020, 68 years later than the group's average year built (1952).

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. Bronx Grove II's 23.8 kBtu/ft² across 140,000 sq ft works out to about 3.3 billion Btu (977 MWh-equivalent) in 2024. Its source EUI of 43.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 429,226 kWh of electricity and 18,629 therms of natural gas for the year.
Which law requires Bronx Grove II to report its energy use?
