What does an ENERGY STAR score of 9 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 9 means the building performs better than about 9% of its national peers. BuildingCensus bands the score into report-card grades; 9 falls in band D — lowest band (1–54). It sits 66 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. 712 S WESTLAKE AVE's 69.5 kBtu/ft² across 20,475 sq ft works out to about 1.4 billion Btu (417 MWh-equivalent) in 2025. Its source EUI of 103.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,885 thousand gallons of water for the year.

Which law requires 712 S WESTLAKE AVE to report its energy use?

712 S WESTLAKE AVE reports under LA Municipal Code Div. 97, §91.9701 (EBEWE), the legal basis of Los Angeles's Existing Buildings Energy & Water Efficiency (EBEWE) program, which publishes each covered building's annual benchmarking results.
