Its site EUI of 140.0 kBtu/ft² is about 87% above the average of 74.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 7.9 kgCO₂e/ft² is about 52% above the group average of 5.2 kgCO₂e/ft².
At 35,280 sq ft, it is about 65% below the average floor area of 100,951 sq ft for those buildings. It was built in 1929, 23 years earlier than the group's average year built (1952).

What does an ENERGY STAR score of 36 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 36 means the building performs better than about 36% of its national peers. BuildingCensus bands the score into report-card grades; 36 falls in band D — lowest band (1–54). It sits 39 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. 345 Bay Ridge Parkway's 140.0 kBtu/ft² across 35,280 sq ft works out to about 4.9 billion Btu (1,448 MWh-equivalent) in 2022. Its source EUI of 174.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 164,241 kWh of electricity for the year.
