How does Sempra Energy Headquarters compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Sempra Energy Headquarters's ENERGY STAR score of 93 compares with an average of 75 across the 4,912 that report a score; it scores higher than 72% of them and lower than 25%. Its site EUI of 44.8 kBtu/ft² is about 21% 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 2.6 kgCO₂e/ft² is about 28% below the group average of 3.6 kgCO₂e/ft².
At 330,399 sq ft, it is about twice the average floor area of 151,937 sq ft for those buildings. It was built in 2015, 30 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.
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Sempra Energy Headquarters's 44.8 kBtu/ft² across 330,399 sq ft works out to about 14.8 billion Btu (4,338 MWh-equivalent) in 2019. The disclosure also reports 1,850,319 kWh of electricity and 83,401 therms of natural gas for the year.
Which law requires Sempra Energy Headquarters to report its energy use?
Sempra Energy Headquarters 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 2019 disclosure (source record california:12425121:2019).
