What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 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. 866 Avenue of the Americas's 69.7 kBtu/ft² across 33,000 sq ft works out to about 2.3 billion Btu (674 MWh-equivalent) in 2024. Its source EUI of 150.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 432,766 kWh of electricity for the year.
