What does an ENERGY STAR score of 22 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 22 means the building performs better than about 22% of its national peers. BuildingCensus bands the score into report-card grades; 22 falls in band D — lowest band (1–54). It sits 53 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. 354 EAST 21 ST REALTY COR's 101.4 kBtu/ft² across 27,246 sq ft works out to about 2.8 billion Btu (810 MWh-equivalent) in 2022. Its source EUI of 132.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 119,619 kWh of electricity and 2,460 thousand gallons of water for the year.
