How does The Emerald Tower compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. The Emerald Tower's ENERGY STAR score of 99 compares with an average of 75 across the 4,912 that report a score; it scores higher than 88% of them and lower than 9%. Its site EUI of 30.7 kBtu/ft² is about half of 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 1.9 kgCO₂e/ft² is about half of the group average of 3.6 kgCO₂e/ft².
At 454,302 sq ft, it is about 199% above the average floor area of 151,937 sq ft for those buildings. Its 1985 construction date is close to 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 The Emerald Tower's energy performance changed over time?
BuildingCensus holds 6 California disclosures for The Emerald Tower, covering report years 2018, 2019, 2020, 2021, 2023, 2024. Its ENERGY STAR score went from 98 in 2018 to 99 in 2024 (+1 points); its best year on file was 2023, at 100. Site EUI moved from 35.7 kBtu/ft² (2018) to 30.7 kBtu/ft² (2024), a 14% decrease. Reported emissions went from 1,092 tCO₂e to 851 tCO₂e over the same span (down 22%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. The Emerald Tower's 30.7 kBtu/ft² across 454,302 sq ft works out to about 13.9 billion Btu (4,087 MWh-equivalent) in 2024. The disclosure also reports 2,470,477 kWh of electricity and 54,815 therms of natural gas for the year.
Which law requires The Emerald Tower to report its energy use?
The Emerald Tower 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:2245464:2024). 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.
