Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has 8723 ALDEN DR's energy performance changed over time?
BuildingCensus holds 9 Los Angeles disclosures for 8723 ALDEN DR, covering report years 2017–2025. Its ENERGY STAR score was 1 in both 2017 and 2021. Site EUI moved from 314.5 kBtu/ft² (2017) to 340.8 kBtu/ft² (2025), an 8% increase. Reported emissions went from 2,010 tCO₂e to 1,875 tCO₂e over the same span (down 7%).
What does a site EUI of 340.8 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. 8723 ALDEN DR's 340.8 kBtu/ft² across 98,809 sq ft works out to about 33.7 billion Btu (9,869 MWh-equivalent) in 2025. Its source EUI of 735.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,224 thousand gallons of water for the year.
Which law requires 8723 ALDEN DR to report its energy use?
8723 ALDEN DR 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:449527845735:2025). EBEWE requires annual benchmarking plus audits/retro-commissioning every five years for privately owned buildings of 20,000 sq ft or more; non-compliance carries a $202 fee (LAMC §91.9712) plus possible late fees.
