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. Hca/Public Health/5Th Street's 287.2 kBtu/ft² across 32,832 sq ft works out to about 9.4 billion Btu (2,763 MWh-equivalent) in 2023.
