How has 9171 OSO AVE's energy performance changed over time?
BuildingCensus holds 9 Los Angeles disclosures for 9171 OSO AVE, covering report years 2017–2025. Site EUI moved from 55.2 kBtu/ft² (2018) to 45.5 kBtu/ft² (2025), a 18% decrease. Reported emissions went from 254 tCO₂e to 170 tCO₂e over the same span (down 33%).
What does a site EUI of 45.5 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. 9171 OSO AVE's 45.5 kBtu/ft² across 65,560 sq ft works out to about 3 billion Btu (874 MWh-equivalent) in 2025. Its source EUI of 126.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,068 thousand gallons of water for the year.
Which law requires 9171 OSO AVE to report its energy use?
9171 OSO AVE reports under LA Municipal Code Div. 97, §91.9701 (EBEWE), the legal basis of Los Angeles's Existing Buildings Energy & Water Efficiency (EBEWE) program, which publishes each covered building's annual benchmarking results.
