What does an ENERGY STAR score of 15 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 15 means the building performs better than about 15% of its national peers. BuildingCensus bands the score into report-card grades; 15 falls in band D — lowest band (1–54). It sits 60 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. 309 East 103rd Street's 82.6 kBtu/ft² across 31,450 sq ft works out to about 2.6 billion Btu (761 MWh-equivalent) in 2024. Its source EUI of 147.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 321,194 kWh of electricity, 15,019 therms of natural gas and 361 thousand gallons of water for the year.
