What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 11728 WILSHIRE BLVD's 48.7 kBtu/ft² across 726,084 sq ft works out to about 35.4 billion Btu (10,363 MWh-equivalent) in 2025. Its source EUI of 63.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher.

Which law requires 11728 WILSHIRE BLVD to report its energy use?

11728 WILSHIRE BLVD 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. The record shown here is the report-year 2025 disclosure (source record la:421978840306:2025). EBEWE requires annual benchmarking plus audits/retro-commissioning every five years for privately owned buildings of 20,000 sq ft or more; non-compliance carries a $202 fee (LAMC §91.9712) plus possible late fees.
