What does an ENERGY STAR score of 54 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 54 means the building performs better than about 54% of its national peers. BuildingCensus bands the score into report-card grades; 54 falls in band D — lowest band (1–54). It sits 21 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. 900 S SERRANO AVE's 58.8 kBtu/ft² across 47,912 sq ft works out to about 2.8 billion Btu (826 MWh-equivalent) in 2025. Its source EUI of 78.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,123 thousand gallons of water for the year.

Which law requires 900 S SERRANO AVE to report its energy use?

900 S SERRANO 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.
