Its site EUI of 150.8 kBtu/ft² is about 60% above the average of 94.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 9.2 kgCO₂e/ft² is about 18% above the group average of 7.8 kgCO₂e/ft².
At 471,985 sq ft, it is about 244% above the average floor area of 137,256 sq ft for those buildings. It was built in 1990, 15 years later than the group's average year built (1975).

What does an ENERGY STAR score of 25 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 25 means the building performs better than about 25% of its national peers. BuildingCensus bands the score into report-card grades; 25 falls in band D — lowest band (1–54). It sits 50 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. Millennium Broadway's 150.8 kBtu/ft² across 471,985 sq ft works out to about 71.2 billion Btu (20,859 MWh-equivalent) in 2022. Its source EUI of 226.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,355,804 kWh of electricity for the year.
