How does Hawthorne Plaza compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Hawthorne Plaza's ENERGY STAR score of 96 compares with an average of 75 across the 4,912 that report a score; it scores higher than 80% of them and lower than 18%. Its site EUI of 29.3 kBtu/ft² is about half of the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.9 kgCO₂e/ft² is about half of the group average of 3.6 kgCO₂e/ft².
At 409,082 sq ft, it is about 169% above the average floor area of 151,937 sq ft for those buildings. Its 1987 construction date is close to the group's average year built (1985). 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 Hawthorne Plaza's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Hawthorne Plaza, covering report years 2018, 2020, 2022. Its ENERGY STAR score went from 89 in 2018 to 96 in 2022 (+7 points); its best year on file was 2020, at 96. Site EUI moved from 33.5 kBtu/ft² (2018) to 29.3 kBtu/ft² (2022), a 13% decrease. Reported emissions went from 916 tCO₂e to 760 tCO₂e over the same span (down 17%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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 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. Hawthorne Plaza's 29.3 kBtu/ft² across 409,082 sq ft works out to about 12 billion Btu (3,513 MWh-equivalent) in 2022. The disclosure also reports 2,263,781 kWh of electricity and 43,395 therms of natural gas for the year.
Which law requires Hawthorne Plaza to report its energy use?
Hawthorne Plaza 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 2022 disclosure (source record california:6699622:2022).
