What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 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. California Bank & Trust's 64.0 kBtu/ft² across 70,095 sq ft works out to about 4.5 billion Btu (1,315 MWh-equivalent) in 2024. The disclosure also reports 832,182 kWh of electricity and 16,603 therms of natural gas for the year.
