What does an ENERGY STAR score of 9 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 9 means the building performs better than about 9% of its national peers. BuildingCensus bands the score into report-card grades; 9 falls in band D — lowest band (1–54). It sits 66 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. 15 EAST 84 STREET's 83.7 kBtu/ft² across 25,486 sq ft works out to about 2.1 billion Btu (625 MWh-equivalent) in 2024. Its source EUI of 179.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 389,474 kWh of electricity, 8,039 therms of natural gas and 607 thousand gallons of water for the year.
