Its site EUI of 13.3 kBtu/ft² is about 76% 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 0.9 kgCO₂e/ft² is about 76% below the group average of 3.6 kgCO₂e/ft².
At 63,412 sq ft, it is about 58% below 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 110 Theory's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 110 Theory, covering report years 2018–2024. Its ENERGY STAR score went from 79 in 2018 to 99 in 2024 (+20 points). Site EUI moved from 63.9 kBtu/ft² (2018) to 13.3 kBtu/ft² (2024), a 79% decrease. Reported emissions went from 262 tCO₂e to 56 tCO₂e over the same span (down 79%).
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. 110 Theory's 13.3 kBtu/ft² across 63,412 sq ft works out to about 0.8 billion Btu (247 MWh-equivalent) in 2024. The disclosure also reports 241,339 kWh of electricity and 183 therms of natural gas for the year.
Which law requires 110 Theory to report its energy use?
110 Theory 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:3122693:2024). 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.
