Its site EUI of 29.8 kBtu/ft² is about 33% below the average of 44.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 322,943 sq ft, it is about twice the average floor area of 147,328 sq ft for those buildings. It was built in 1999, 24 years later 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 6301 OWENSMOUTH AVE's energy performance changed over time?

BuildingCensus holds 10 Los Angeles disclosures for 6301 OWENSMOUTH AVE, covering report years 2016–2025. Its ENERGY STAR score went from 97 in 2016 to 99 in 2025 (+2 points). Site EUI moved from 40.0 kBtu/ft² (2016) to 29.8 kBtu/ft² (2025), a 26% decrease. Reported emissions went from 1,120 tCO₂e to 550 tCO₂e over the same span (down 51%).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. 6301 OWENSMOUTH AVE's 29.8 kBtu/ft² across 322,943 sq ft works out to about 9.6 billion Btu (2,820 MWh-equivalent) in 2025. Its source EUI of 83.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,239 thousand gallons of water for the year.
