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. K135 (OECID: 0300142; BBL: 3046730001)'s 99.3 kBtu/ft² across 69,600 sq ft works out to about 6.9 billion Btu (2,025 MWh-equivalent) in 2024. Its source EUI of 133.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 340,573 kWh of electricity, 51,997 therms of natural gas and 0 thousand gallons of water for the year.
