What does an ENERGY STAR score of 29 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 29 means the building performs better than about 29% of its national peers. BuildingCensus bands the score into report-card grades; 29 falls in band D — lowest band (1–54). It sits 46 points below 75, the threshold for ENERGY STAR certification. In Los Angeles, 63% 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. 3023 S WESTERN's 54.8 kBtu/ft² across 56,753 sq ft works out to about 3.1 billion Btu (911 MWh-equivalent) in 2025. Its source EUI of 110.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,250 thousand gallons of water for the year.
