What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 falls in band A — high performer (85–100). 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. KM - 74 Ross Street's 74.5 kBtu/ft² across 93,538 sq ft works out to about 7 billion Btu (2,042 MWh-equivalent) in 2023. Its source EUI of 78.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 69,694 therms of natural gas for the year.
