What does a site EUI of 89.1 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. 101 POST ST's 89.1 kBtu/ft² across 17,090 sq ft works out to about 1.5 billion Btu (446 MWh-equivalent) in 2025. Its source EUI of 197.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 281,794 kWh of electricity for the year.
Which law requires 101 POST ST to report its energy use?
101 POST 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:0310/001:2025).
