What does a site EUI of 8.8 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. Sharon Building's 8.8 kBtu/ft² across 103,861 sq ft works out to about 0.9 billion Btu (268 MWh-equivalent) in 2025. Its source EUI of 24.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 266,577 kWh of electricity and 72 therms of natural gas for the year.
Which law requires Sharon Building to report its energy use?
Sharon 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:3707/035:2025).
