What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. 620 Avenue of the Americas's 52.9 kBtu/ft² across 731,613 sq ft works out to about 38.7 billion Btu (11,343 MWh-equivalent) in 2024. Its source EUI of 123.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,415,076 kWh of electricity, 89 therms of natural gas and 8,102 thousand gallons of water for the year.
