Its site EUI of 30.5 kBtu/ft² is about half of 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 2.0 kgCO₂e/ft² is about 44% below the group average of 3.6 kgCO₂e/ft².
At 249,831 sq ft, it is about 64% above the average floor area of 151,937 sq ft for those buildings. It was built in 2018, 33 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 Us-Sfo-Twn510's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Us-Sfo-Twn510, covering report years 2023–2024. Site EUI moved from 28.4 kBtu/ft² (2023) to 30.5 kBtu/ft² (2024), an 7% increase. Reported emissions went from 589 tCO₂e to 500 tCO₂e over the same span (down 15%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. Us-Sfo-Twn510's 30.5 kBtu/ft² across 249,831 sq ft works out to about 7.6 billion Btu (2,233 MWh-equivalent) in 2024. The disclosure also reports 2,100,465 kWh of electricity and 4,515 therms of natural gas for the year.
Which law requires Us-Sfo-Twn510 to report its energy use?
