Its site EUI of 80.9 kBtu/ft² is about 25% 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 6.6 kgCO₂e/ft² is about 13% above the group average of 5.8 kgCO₂e/ft².
At 191,000 sq ft, it is roughly in line with the average floor area of 205,440 sq ft for those buildings. It was built in 1964, 24 years later than the group's average year built (1940).

What does an ENERGY STAR score of 73 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 73 means the building performs better than about 73% of its national peers. BuildingCensus bands the score into report-card grades; 73 falls in band B — above median (70–84). It sits 2 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. 300 E 42nd Street's 80.9 kBtu/ft² across 191,000 sq ft works out to about 15.5 billion Btu (4,529 MWh-equivalent) in 2024. Its source EUI of 136.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,362,916 kWh of electricity and 1,801 thousand gallons of water for the year.
