The latest disclosures cover 10,630 multifamily housing buildings in California, out of 40,029 buildings citywide. 600 Whisman's ENERGY STAR score of 87 compares with an average of 82 across the 9,612 that report a score; it scores higher than 42% of them and lower than 57%. Its site EUI of 21.6 kBtu/ft² is about 37% below the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.2 kgCO₂e/ft² is about 41% below the group average of 2.1 kgCO₂e/ft².

At 95,796 sq ft, it is about 37% below the average floor area of 150,919 sq ft for those buildings. It was built in 1963, 25 years earlier than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has 600 Whisman's energy performance changed over time?

BuildingCensus holds 2 California disclosures for 600 Whisman, covering report years 2023–2024. Its ENERGY STAR score went from 100 in 2023 to 87 in 2024 (-13 points); its best year on file was 2023, at 100. Site EUI moved from 15.1 kBtu/ft² (2023) to 21.6 kBtu/ft² (2024), an 43% increase. Reported emissions went from 83 tCO₂e to 119 tCO₂e over the same span (up 42%).

What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. 600 Whisman's 21.6 kBtu/ft² across 95,796 sq ft works out to about 2.1 billion Btu (606 MWh-equivalent) in 2024. The disclosure also reports 250,767 kWh of electricity and 11,641 therms of natural gas for the year.

Which law requires 600 Whisman to report its energy use?

600 Whisman 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:33915581:2024). 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.
