How has 135 4th St's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 135 4th St, covering report years 2011–2025. Site EUI moved from 132.5 kBtu/ft² (2012) to 98.1 kBtu/ft² (2025), a 26% decrease. Reported emissions went from 3,300 tCO₂e to 1,954 tCO₂e over the same span (down 41%).
What does a site EUI of 98.1 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. 135 4th St's 98.1 kBtu/ft² across 357,659 sq ft works out to about 35.1 billion Btu (10,283 MWh-equivalent) in 2025. Its source EUI of 211.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,472,693 kWh of electricity and 130,151 therms of natural gas for the year.
Which law requires 135 4th St to report its energy use?
