The latest disclosures cover 676 office buildings in Los Angeles, out of 11,498 buildings citywide. 520 S SEPULVEDA BLVD's ENERGY STAR score of 92 compares with an average of 77 across the 591 that report a score; it scores higher than 66% of them and lower than 32%. Its site EUI of 23.1 kBtu/ft² is about half of the average of 44.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 20,095 sq ft, it is about 86% below the average floor area of 147,328 sq ft for those buildings. It was built in 1970, 5 years earlier than the group's average year built (1975). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has 520 S SEPULVEDA BLVD's energy performance changed over time?

BuildingCensus holds 8 Los Angeles disclosures for 520 S SEPULVEDA BLVD, covering report years 2018–2025. Its ENERGY STAR score went from 78 in 2018 to 92 in 2025 (+14 points); its best year on file was 2024, at 95. Site EUI moved from 41.2 kBtu/ft² (2018) to 23.1 kBtu/ft² (2025), a 44% decrease. Reported emissions went from 60 tCO₂e to 27 tCO₂e over the same span (down 56%).

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. 520 S SEPULVEDA BLVD's 23.1 kBtu/ft² across 20,095 sq ft works out to about 0.5 billion Btu (136 MWh-equivalent) in 2025. Its source EUI of 64.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 139 thousand gallons of water for the year.

Which law requires 520 S SEPULVEDA BLVD to report its energy use?

520 S SEPULVEDA 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:422475846653:2025). 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.
