What does an ENERGY STAR score of 52 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 52 means the building performs better than about 52% of its national peers. BuildingCensus bands the score into report-card grades; 52 falls in band D — lowest band (1–54). It sits 23 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. 845 Grand's 39.7 kBtu/ft² across 31,425 sq ft works out to about 1.2 billion Btu (366 MWh-equivalent) in 2024. Its source EUI of 111.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 366,024 kWh of electricity and 1,311 thousand gallons of water for the year.
