Its site EUI of 6.5 kBtu/ft² is about 83% below the average of 39.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.8 kgCO₂e/ft² is about 76% below the group average of 3.1 kgCO₂e/ft².

At 25,400 sq ft, it is about 69% below the average floor area of 83,240 sq ft for those buildings. It was built in 1964, 11 years later than the group's average year built (1953).

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 314 24th Street's 6.5 kBtu/ft² across 25,400 sq ft works out to about 0.2 billion Btu (48 MWh-equivalent) in 2024. Its source EUI of 18.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 48,674 kWh of electricity for the year.

Which law requires 314 24th Street to report its energy use?
