What does an ENERGY STAR score of 26 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 26 means the building performs better than about 26% of its national peers. BuildingCensus bands the score into report-card grades; 26 falls in band D — lowest band (1–54). It sits 49 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. One Carnegie Hill's 91.0 kBtu/ft² across 494,765 sq ft works out to about 45 billion Btu (13,195 MWh-equivalent) in 2024. Its source EUI of 142.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,877,461 kWh of electricity and 317,950 therms of natural gas for the year.
