What does an ENERGY STAR score of 4 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 4 means the building performs better than about 4% of its national peers. BuildingCensus bands the score into report-card grades; 4 falls in band D — lowest band (1–54). It sits 71 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. 25 Claremont's 112.9 kBtu/ft² across 62,244 sq ft works out to about 7 billion Btu (2,060 MWh-equivalent) in 2024. Its source EUI of 130.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 126,032 kWh of electricity, 66,002 therms of natural gas and 2,441 thousand gallons of water for the year.
