429 Santa Monica

How does 429 Santa Monica compare with other mixed use property buildings in California?

The latest disclosures cover 294 mixed use property buildings in California, out of 40,029 buildings citywide. 429 Santa Monica's ENERGY STAR score of 78 compares with an average of 78 across the 83 that report a score; it scores higher than 37% of them and lower than 61%. Its site EUI of 42.4 kBtu/ft² is about 40% below the average of 70.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.8 kgCO₂e/ft² is about 36% below the group average of 4.3 kgCO₂e/ft².

At 83,798 sq ft, it is about 58% below the average floor area of 200,559 sq ft for those buildings. Its 1982 construction date is close to the group's average year built (1984). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².

How has 429 Santa Monica's energy performance changed over time?

BuildingCensus holds 6 California disclosures for 429 Santa Monica, covering report years 2018, 2019, 2020, 2022, 2023, 2024. Its ENERGY STAR score went from 83 in 2018 to 78 in 2024 (-5 points); its best year on file was 2020, at 89. Site EUI moved from 46.3 kBtu/ft² (2018) to 42.4 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 272 tCO₂e to 230 tCO₂e over the same span (down 15%).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 falls in band B — above median (70–84). 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 California, 65% 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. 429 Santa Monica's 42.4 kBtu/ft² across 83,798 sq ft works out to about 3.6 billion Btu (1,041 MWh-equivalent) in 2024. The disclosure also reports 922,041 kWh of electricity and 4,073 therms of natural gas for the year.

Which law requires 429 Santa Monica to report its energy use?

429 Santa Monica reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:6061684:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
