What does an ENERGY STAR score of 10 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 10 means the building performs better than about 10% of its national peers. BuildingCensus bands the score into report-card grades; 10 falls in band D — lowest band (1–54). It sits 65 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. Broadcom Innovation E4's 165.5 kBtu/ft² across 102,821 sq ft works out to about 17 billion Btu (4,987 MWh-equivalent) in 2024. The disclosure also reports 4,515,395 kWh of electricity for the year.
