How has 21100 S WESTERN AVE's energy performance changed over time?
BuildingCensus holds 10 Los Angeles disclosures for 21100 S WESTERN AVE, covering report years 2016–2025. Site EUI moved from 447.2 kBtu/ft² (2016) to 348.1 kBtu/ft² (2025), a 22% decrease. Reported emissions went from 3,763 tCO₂e to 2,395 tCO₂e over the same span (down 36%).
What does a site EUI of 348.1 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. 21100 S WESTERN AVE's 348.1 kBtu/ft² across 124,337 sq ft works out to about 43.3 billion Btu (12,685 MWh-equivalent) in 2025. Its source EUI of 701.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,156 thousand gallons of water for the year.
Which law requires 21100 S WESTERN AVE to report its energy use?
21100 S WESTERN 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. The record shown here is the report-year 2025 disclosure (source record la:468103764127:2025).
