What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 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. Wallack - 860 5th Ave's 62.4 kBtu/ft² across 285,813 sq ft works out to about 17.8 billion Btu (5,227 MWh-equivalent) in 2024. Its source EUI of 95.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,453,790 kWh of electricity and 123,086 therms of natural gas for the year.
