The latest disclosures cover 676 office buildings in Los Angeles, out of 11,498 buildings citywide. 10250 CONSTELLATION BLVD's ENERGY STAR score of 91 compares with an average of 77 across the 591 that report a score; it scores higher than 62% of them and lower than 34%. Its site EUI of 54.6 kBtu/ft² is about 23% above the average of 44.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group.

At 810,474 sq ft, it is about 450% above the average floor area of 147,328 sq ft for those buildings. It was built in 2003, 28 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 10250 CONSTELLATION BLVD's energy performance changed over time?

BuildingCensus holds 10 Los Angeles disclosures for 10250 CONSTELLATION BLVD, covering report years 2016–2025. Its ENERGY STAR score went from 93 in 2016 to 91 in 2025 (-2 points); its best year on file was 2023, at 99. Site EUI moved from 65.0 kBtu/ft² (2016) to 54.6 kBtu/ft² (2025), a 16% decrease. Reported emissions went from 3,562 tCO₂e to 2,322 tCO₂e over the same span (down 35%).

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. 10250 CONSTELLATION BLVD's 54.6 kBtu/ft² across 810,474 sq ft works out to about 44.3 billion Btu (12,969 MWh-equivalent) in 2025. Its source EUI of 98.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,953 thousand gallons of water for the year.

Which law requires 10250 CONSTELLATION BLVD to report its energy use?

10250 CONSTELLATION 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:435226843421:2025). 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.
