How does 38 Technology compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. 38 Technology's ENERGY STAR score of 64 compares with an average of 75 across the 4,912 that report a score; it scores higher than 25% of them and lower than 75%. Its site EUI of 50.6 kBtu/ft² is about 10% 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 3.0 kgCO₂e/ft² is about 17% below the group average of 3.6 kgCO₂e/ft².
At 53,520 sq ft, it is about 65% 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 38 Technology's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 38 Technology, covering report years 2018–2024. Its ENERGY STAR score went from 26 in 2018 to 64 in 2024 (+38 points); its best year on file was 2020, at 77. Site EUI moved from 94.4 kBtu/ft² (2018) to 50.6 kBtu/ft² (2024), a 46% decrease. Reported emissions went from 328 tCO₂e to 160 tCO₂e over the same span (down 51%).
What does an ENERGY STAR score of 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 points below 75, the threshold for ENERGY STAR certification. 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. 38 Technology's 50.6 kBtu/ft² across 53,520 sq ft works out to about 2.7 billion Btu (794 MWh-equivalent) in 2024. The disclosure also reports 475,104 kWh of electricity and 9,958 therms of natural gas for the year.
Which law requires 38 Technology to report its energy use?
38 Technology 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:3205789:2024). 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.
