What does an ENERGY STAR score of 30 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 30 means the building performs better than about 30% of its national peers. BuildingCensus bands the score into report-card grades; 30 falls in band D — lowest band (1–54). It sits 45 points below 75, the threshold for ENERGY STAR certification. In California, 65% 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. Adm/Glc 475189/781 First Ave's 131.3 kBtu/ft² across 54,406 sq ft works out to about 7.1 billion Btu (2,094 MWh-equivalent) in 2018.
