Its site EUI of 77.7 kBtu/ft² is about 18% below the average of 94.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 5.8 kgCO₂e/ft² is about 26% below the group average of 7.8 kgCO₂e/ft².
At 103,429 sq ft, it is about 25% below the average floor area of 137,256 sq ft for those buildings. It was built in 1950, 25 years earlier than the group's average year built (1975). Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².
What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 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. Radisson Rockefeller Center's 77.7 kBtu/ft² across 103,429 sq ft works out to about 8 billion Btu (2,355 MWh-equivalent) in 2022. Its source EUI of 175.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,621,866 kWh of electricity and 9,420 thousand gallons of water for the year.
