How does Hobart Building compare with other office buildings in California?
The latest disclosures cover 6,214 office buildings in California, out of 40,029 buildings citywide. Hobart Building's ENERGY STAR score of 37 compares with an average of 75 across the 4,912 that report a score; it scores higher than 11% of them and lower than 89%. Its site EUI of 104.3 kBtu/ft² is about 85% above the average of 56.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.8 kgCO₂e/ft² is about 61% above the group average of 3.6 kgCO₂e/ft².
At 75,482 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 1914, 71 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.
What does an ENERGY STAR score of 37 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 37 means the building performs better than about 37% of its national peers. BuildingCensus bands the score into report-card grades; 37 falls in band D — lowest band (1–54). It sits 38 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. Hobart Building's 104.3 kBtu/ft² across 75,482 sq ft works out to about 7.9 billion Btu (2,307 MWh-equivalent) in 2024. The disclosure also reports 400,175 kWh of electricity and 65,087 therms of natural gas for the year.
Which law requires Hobart Building to report its energy use?
Hobart 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:53301792:2024).
