Its site EUI of 107.7 kBtu/ft² is about 67% above the average of 64.5 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 9.4 kgCO₂e/ft² is about 62% above the group average of 5.8 kgCO₂e/ft².
At 218,566 sq ft, it is roughly in line with the average floor area of 205,440 sq ft for those buildings. It was built in 2023, 83 years later than the group's average year built (1940).

What does an ENERGY STAR score of 40 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 40 means the building performs better than about 40% of its national peers. BuildingCensus bands the score into report-card grades; 40 falls in band D — lowest band (1–54). It sits 35 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. 80 20th Street's 107.7 kBtu/ft² across 218,566 sq ft works out to about 23.5 billion Btu (6,899 MWh-equivalent) in 2024. Its source EUI of 217.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,815,720 kWh of electricity and 105,152 therms of natural gas for the year.
