What does an ENERGY STAR score of 50 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 50 means the building performs better than about 50% of its national peers. BuildingCensus bands the score into report-card grades; 50 falls in band D — lowest band (1–54). It sits 25 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. 10 WEST 46 STREET's 82.7 kBtu/ft² across 76,008 sq ft works out to about 6.3 billion Btu (1,842 MWh-equivalent) in 2024. Its source EUI of 178.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,167,402 kWh of electricity and 23,033 therms of natural gas for the year.
