How has 23001 W ROSCOE BLVD's energy performance changed over time?
BuildingCensus holds 10 Los Angeles disclosures for 23001 W ROSCOE BLVD, covering report years 2016–2025. Its ENERGY STAR score went from 2 in 2016 to 5 in 2025 (+3 points). Site EUI moved from 144.6 kBtu/ft² (2016) to 118.6 kBtu/ft² (2025), a 18% decrease. Reported emissions went from 633 tCO₂e to 391 tCO₂e over the same span (down 38%).
What does an ENERGY STAR score of 5 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 5 means the building performs better than about 5% of its national peers. BuildingCensus bands the score into report-card grades; 5 falls in band D — lowest band (1–54). It sits 70 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. 23001 W ROSCOE BLVD's 118.6 kBtu/ft² across 57,723 sq ft works out to about 6.8 billion Btu (2,006 MWh-equivalent) in 2025. Its source EUI of 332.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 494 thousand gallons of water for the year.
Which law requires 23001 W ROSCOE BLVD to report its energy use?
23001 W ROSCOE 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.
