The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. One Front Street's ENERGY STAR score of 93 compares with an average of 75 across the 4,912 that report a score; it scores higher than 72% of them and lower than 25%. Its site EUI of 38.7 kBtu/ft² is about 31% 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 2.4 kgCO₂e/ft² is about 33% below the group average of 3.6 kgCO₂e/ft².
At 754,728 sq ft, it is about 397% above the average floor area of 151,937 sq ft for those buildings. It was built in 1979, 6 years earlier than the group's average year built (1985).

How has One Front Street's energy performance changed over time?
BuildingCensus holds 7 California disclosures for One Front Street, covering report years 2018–2024. Its ENERGY STAR score went from 87 in 2018 to 93 in 2024 (+6 points). Site EUI moved from 48.4 kBtu/ft² (2018) to 38.7 kBtu/ft² (2024), a 20% decrease. Reported emissions went from 2,383 tCO₂e to 1,818 tCO₂e over the same span (down 24%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. One Front Street's 38.7 kBtu/ft² across 754,728 sq ft works out to about 29.2 billion Btu (8,560 MWh-equivalent) in 2024. The disclosure also reports 5,312,361 kWh of electricity and 115,730 therms of natural gas for the year.
Which law requires One Front Street to report its energy use?
One Front Street 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:1409806:2024).
