600 Clipper

How does 600 Clipper compare with other office buildings in California?

The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. 600 Clipper's ENERGY STAR score of 78 compares with an average of 75 across the 4,912 that report a score; it scores higher than 39% of them and lower than 59%. Its site EUI of 71.6 kBtu/ft² is about 27% above the average of 56.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 4.3 kgCO₂e/ft² is about 19% above the group average of 3.6 kgCO₂e/ft².

At 158,596 sq ft, it is roughly in line with the average floor area of 151,937 sq ft for those buildings. It was built in 1998, 13 years later 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 600 Clipper's energy performance changed over time?

BuildingCensus holds 3 California disclosures for 600 Clipper, covering report years 2022–2024. Its ENERGY STAR score went from 82 in 2022 to 78 in 2024 (-4 points); its best year on file was 2022, at 82. Site EUI moved from 63.5 kBtu/ft² (2022) to 71.6 kBtu/ft² (2024), an 13% increase. Reported emissions went from 617 tCO₂e to 682 tCO₂e over the same span (up 10%).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 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. 600 Clipper's 71.6 kBtu/ft² across 158,596 sq ft works out to about 11.4 billion Btu (3,328 MWh-equivalent) in 2024. The disclosure also reports 1,845,181 kWh of electricity and 49,666 therms of natural gas for the year.

Which law requires 600 Clipper to report its energy use?

600 Clipper 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:15966339:2024). 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.
