What does an ENERGY STAR score of 1 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: 1 is the bottom of the scale. BuildingCensus bands the score into report-card grades; 1 falls in band D — lowest band (1–54). It sits 74 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. 300 Fir St's 335.3 kBtu/ft² across 66,009 sq ft works out to about 22.1 billion Btu (6,486 MWh-equivalent) in 2018.
