How does Whs 3 (20850 Alameda) compare with other non-refrigerated warehouse buildings in California?
The latest disclosures cover 2,867 non-refrigerated warehouse buildings in California, out of 40,029 buildings citywide. Whs 3 (20850 Alameda)'s ENERGY STAR score of 94 compares with an average of 68 across the 2,227 that report a score; it scores higher than 75% of them and lower than 23%. Its site EUI of 10.4 kBtu/ft² is about half of the average of 21.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is about half of the group average of 1.4 kgCO₂e/ft².
At 85,552 sq ft, it is about half of the average floor area of 173,929 sq ft for those buildings. Its 1987 construction date is close to the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².
What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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. Whs 3 (20850 Alameda)'s 10.4 kBtu/ft² across 85,552 sq ft works out to about 0.9 billion Btu (261 MWh-equivalent) in 2023. The disclosure also reports 260,757 kWh of electricity for the year.
Which law requires Whs 3 (20850 Alameda) to report its energy use?
Whs 3 (20850 Alameda) 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 2023 disclosure (source record california:12434111:2023).
