What does an ENERGY STAR score of 26 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 26 means the building performs better than about 26% of its national peers. BuildingCensus bands the score into report-card grades; 26 falls in band D — lowest band (1–54). It sits 49 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. 15620 Leffingwell Rd's 53.6 kBtu/ft² across 58,731 sq ft works out to about 3.1 billion Btu (923 MWh-equivalent) in 2024. The disclosure also reports 329,329 kWh of electricity and 20,184 therms of natural gas for the year.
