Its site EUI of 63.4 kBtu/ft² is about 15% 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 4.0 kgCO₂e/ft² is about 22% below the group average of 5.2 kgCO₂e/ft².
At 67,500 sq ft, it is about 33% below the average floor area of 100,951 sq ft for those buildings. It was built in 1941, 11 years earlier than the group's average year built (1952).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 falls in band B — above median (70–84). 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. 800 Greenwood Ave's 63.4 kBtu/ft² across 67,500 sq ft works out to about 4.3 billion Btu (1,254 MWh-equivalent) in 2024. Its source EUI of 85.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 213,296 kWh of electricity and 35,491 therms of natural gas for the year.
