What does an ENERGY STAR score of 53 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 53 means the building performs better than about 53% of its national peers. BuildingCensus bands the score into report-card grades; 53 falls in band D — lowest band (1–54). It sits 22 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. 401 S HOOVER ST's 37.0 kBtu/ft² across 47,731 sq ft works out to about 1.8 billion Btu (518 MWh-equivalent) in 2025. Its source EUI of 72.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,093 thousand gallons of water for the year.

Which law requires 401 S HOOVER ST to report its energy use?

401 S HOOVER ST 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:475472846550:2025). 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.
