What does a site EUI of 108.1 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 MISSISSIPPI ST's 108.1 kBtu/ft² across 28,454 sq ft works out to about 3.1 billion Btu (901 MWh-equivalent) in 2025. Its source EUI of 264.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 720,199 kWh of electricity and 6,174 therms of natural gas for the year.
Which law requires 135 MISSISSIPPI ST to report its energy use?
135 MISSISSIPPI ST reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:3987/007:2025).
