What does an ENERGY STAR score of 74 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 74 means the building performs better than about 74% of its national peers. BuildingCensus bands the score into report-card grades; 74 falls in band B — above median (70–84). It sits 1 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. 3435 Routier Rd's 36.6 kBtu/ft² across 106,659 sq ft works out to about 3.9 billion Btu (1,144 MWh-equivalent) in 2021. The disclosure also reports 657,669 kWh of electricity and 16,532 therms of natural gas for the year.
