What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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. 20 Cliff St.'s 61.3 kBtu/ft² across 146,640 sq ft works out to about 9 billion Btu (2,634 MWh-equivalent) in 2024. Its source EUI of 82.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 435,294 kWh of electricity, 73,095 therms of natural gas and 3,084 thousand gallons of water for the year.
