How has 180-Stephens Institute's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for 180-Stephens Institute, covering report years 2011–2025. Site EUI moved from 108.7 kBtu/ft² (2011) to 136.0 kBtu/ft² (2025), an 25% increase. Reported emissions went from 1,878 tCO₂e to 1,602 tCO₂e over the same span (down 15%).
What does a site EUI of 136.0 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. 180-Stephens Institute's 136.0 kBtu/ft² across 190,066 sq ft works out to about 25.8 billion Btu (7,576 MWh-equivalent) in 2025. Its source EUI of 268.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,655,666 kWh of electricity for the year.
Which law requires 180-Stephens Institute to report its energy use?
180-Stephens Institute 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:3722/022:2025).
