The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Ten Almaden'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 47.9 kBtu/ft² is about 15% 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 2.8 kgCO₂e/ft² is about 24% below the group average of 3.6 kgCO₂e/ft².
At 329,732 sq ft, it is about twice 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 Ten Almaden's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Ten Almaden, covering report years 2018–2024. Its ENERGY STAR score was 82 in both 2018 and 2024. Site EUI moved from 68.8 kBtu/ft² (2018) to 47.9 kBtu/ft² (2024), a 30% decrease. Reported emissions went from 1,373 tCO₂e to 905 tCO₂e over the same span (down 34%).
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. Ten Almaden's 47.9 kBtu/ft² across 329,732 sq ft works out to about 15.8 billion Btu (4,629 MWh-equivalent) in 2024. The disclosure also reports 2,151,057 kWh of electricity for the year.
Which law requires Ten Almaden to report its energy use?
Ten Almaden 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:1466669:2024).
