What does an ENERGY STAR score of 35 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 35 means the building performs better than about 35% of its national peers. BuildingCensus bands the score into report-card grades; 35 falls in band D — lowest band (1–54). It sits 40 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. 4440 San Juan Ave's 60.8 kBtu/ft² across 55,236 sq ft works out to about 3.4 billion Btu (984 MWh-equivalent) in 2024. The disclosure also reports 341,097 kWh of electricity and 23,779 therms of natural gas for the year.
