At 61,848 sq ft, it is about 63% below the average floor area of 165,572 sq ft for those buildings. It was built in 1914, 52 years earlier than the group's average year built (1967).
How has 1001 CALIFORNIA ST's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for 1001 CALIFORNIA ST, covering report years 2018–2025. Site EUI moved from 18.0 kBtu/ft² (2021) to 20.0 kBtu/ft² (2025), an 11% increase. Reported emissions went from 63 tCO₂e to 68 tCO₂e over the same span (up 8%).
What does a site EUI of 20.0 kBtu/ft² mean?
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. 1001 CALIFORNIA ST's 20.0 kBtu/ft² across 61,848 sq ft works out to about 1.2 billion Btu (363 MWh-equivalent) in 2025. Its source EUI of 35.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 146,610 kWh of electricity and 7,336 therms of natural gas for the year.
Which law requires 1001 CALIFORNIA ST to report its energy use?
