Its site EUI of 33.6 kBtu/ft² is about 40% 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 2.3 kgCO₂e/ft² is about 37% below the group average of 3.6 kgCO₂e/ft².
At 566,318 sq ft, it is about 273% above the average floor area of 151,937 sq ft for those buildings. It was built in 1927, 58 years earlier 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 Russ Building's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Russ Building, covering report years 2018–2024. Its ENERGY STAR score went from 94 in 2018 to 96 in 2024 (+2 points). Site EUI moved from 36.1 kBtu/ft² (2018) to 33.6 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 1,425 tCO₂e to 1,288 tCO₂e over the same span (down 10%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Russ Building's 33.6 kBtu/ft² across 566,318 sq ft works out to about 19 billion Btu (5,577 MWh-equivalent) in 2024. The disclosure also reports 2,624,519 kWh of electricity for the year.
Which law requires Russ Building to report its energy use?
Russ Building 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:26998:2024). 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.
