What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. Harlington: 37-55 77th Street's 72.3 kBtu/ft² across 54,525 sq ft works out to about 3.9 billion Btu (1,155 MWh-equivalent) in 2024. Its source EUI of 103.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 253,778 kWh of electricity, 30,744 therms of natural gas and 3,846 thousand gallons of water for the year.
