Chestnut's ENERGY STAR score of 91 compares with an average of 82 across the 9,612 that report a score; it scores higher than 49% of them and lower than 49%. Its site EUI of 25.4 kBtu/ft² is about 26% 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 1.5 kgCO₂e/ft² is about 28% below the group average of 2.1 kgCO₂e/ft².
At 60,480 sq ft, it is about 60% below the average floor area of 150,919 sq ft for those buildings. It was built in 1997, 9 years later than the group's average year built (1988).

How has Chestnut's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Chestnut, covering report years 2019–2024. Its ENERGY STAR score went from 98 in 2019 to 91 in 2024 (-7 points); its best year on file was 2021, at 99. Site EUI moved from 27.4 kBtu/ft² (2019) to 25.4 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 99 tCO₂e to 91 tCO₂e over the same span (down 8%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. Chestnut's 25.4 kBtu/ft² across 60,480 sq ft works out to about 1.5 billion Btu (450 MWh-equivalent) in 2024. The disclosure also reports 162,606 kWh of electricity and 10,239 therms of natural gas for the year.
Which law requires Chestnut to report its energy use?
Chestnut 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:6793967:2024). 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.
