The latest disclosures cover 392 non-refrigerated warehouse buildings in Los Angeles, out of 11,498 buildings citywide. 9311 OSO AVE's ENERGY STAR score of 90 compares with an average of 68 across the 352 that report a score; it scores higher than 74% of them and lower than 24%. Its site EUI of 6.4 kBtu/ft² is about 67% below the average of 19.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 35,785 sq ft, it is about 38% below the average floor area of 57,664 sq ft for those buildings. It was built in 1977, 5 years later than the group's average year built (1972). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².

How has 9311 OSO AVE's energy performance changed over time?

BuildingCensus holds 8 Los Angeles disclosures for 9311 OSO AVE, covering report years 2018–2025. Its ENERGY STAR score went from 24 in 2018 to 90 in 2025 (+66 points); its best year on file was 2024, at 90. Site EUI moved from 37.2 kBtu/ft² (2018) to 6.4 kBtu/ft² (2025), a 83% decrease. Reported emissions went from 89 tCO₂e to 13 tCO₂e over the same span (down 85%).

What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. 9311 OSO AVE's 6.4 kBtu/ft² across 35,785 sq ft works out to about 0.2 billion Btu (67 MWh-equivalent) in 2025. Its source EUI of 17.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 107 thousand gallons of water for the year.

Which law requires 9311 OSO AVE to report its energy use?

9311 OSO 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. The record shown here is the report-year 2025 disclosure (source record la:387560910065:2025). 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.
