How has Mendelsohn House's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for Mendelsohn House, covering report years 2018–2025. Site EUI moved from 48.9 kBtu/ft² (2018) to 52.2 kBtu/ft² (2025), an 7% increase. Reported emissions went from 383 tCO₂e to 396 tCO₂e over the same span (up 3%).
What does a site EUI of 52.2 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. Mendelsohn House's 52.2 kBtu/ft² across 141,000 sq ft works out to about 7.4 billion Btu (2,157 MWh-equivalent) in 2025. Its source EUI of 70.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 376,045 kWh of electricity and 60,753 therms of natural gas for the year.
Which law requires Mendelsohn House to report its energy use?
Mendelsohn House 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.
