How does Park Plaza compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Park Plaza's ENERGY STAR score of 88 compares with an average of 75 across the 4,912 that report a score; it scores higher than 59% of them and lower than 39%. Its site EUI of 28.5 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 74,875 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. Its 1984 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 Park Plaza's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Park Plaza, covering report years 2018–2024. Its ENERGY STAR score went from 93 in 2018 to 88 in 2024 (-5 points); its best year on file was 2019, at 94. Site EUI moved from 32.8 kBtu/ft² (2018) to 28.5 kBtu/ft² (2024), a 13% decrease. Reported emissions went from 171 tCO₂e to 139 tCO₂e over the same span (down 19%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. Park Plaza's 28.5 kBtu/ft² across 74,875 sq ft works out to about 2.1 billion Btu (625 MWh-equivalent) in 2024. The disclosure also reports 570,609 kWh of electricity for the year.
Which law requires Park Plaza to report its energy use?
Park 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:1935971:2024). 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.
