What does a site EUI of 11.6 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. 251 Kearny Building's 11.6 kBtu/ft² across 31,978 sq ft works out to about 0.4 billion Btu (109 MWh-equivalent) in 2025. Its source EUI of 29.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 89,704 kWh of electricity and 661 therms of natural gas for the year.
Which law requires 251 Kearny Building to report its energy use?
251 Kearny Building 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:0287/001:2025).
