What does an ENERGY STAR score of 55 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 55 means the building performs better than about 55% of its national peers. BuildingCensus bands the score into report-card grades; 55 falls in band C — below median (55–69). It sits 20 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. 1650 Harbor Bay Parkway's 76.9 kBtu/ft² across 125,205 sq ft works out to about 9.6 billion Btu (2,822 MWh-equivalent) in 2024.
