What does an ENERGY STAR score of 66 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 66 means the building performs better than about 66% of its national peers. BuildingCensus bands the score into report-card grades; 66 falls in band C — below median (55–69). It sits 9 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. 21217 GAULT ST's 41.8 kBtu/ft² across 52,247 sq ft works out to about 2.2 billion Btu (640 MWh-equivalent) in 2025. Its source EUI of 67.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,553 thousand gallons of water for the year.
