How does Royal Plaza compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Royal Plaza's ENERGY STAR score of 82 compares with an average of 75 across the 4,912 that report a score; it scores higher than 46% of them and lower than 52%. Its site EUI of 44.3 kBtu/ft² is about 21% below 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 2.9 kgCO₂e/ft² is about 18% below the group average of 3.6 kgCO₂e/ft².
At 78,000 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 1968, 17 years earlier than 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 Royal Plaza's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Royal Plaza, covering report years 2018–2024. Its ENERGY STAR score went from 75 in 2018 to 82 in 2024 (+7 points); its best year on file was 2023, at 85. Site EUI moved from 48.4 kBtu/ft² (2018) to 44.3 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 265 tCO₂e to 229 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. Royal Plaza's 44.3 kBtu/ft² across 78,000 sq ft works out to about 3.5 billion Btu (1,013 MWh-equivalent) in 2024. The disclosure also reports 925,450 kWh of electricity for the year.
Which law requires Royal Plaza to report its energy use?
Royal 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 2024 disclosure (source record california:6367079:2024). 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.
