BuildingCensus holds 10 Los Angeles disclosures for 400 S FLOWER ST, covering report years 2016–2025. Site EUI moved from 5.8 kBtu/ft² (2016) to 3.9 kBtu/ft² (2025), a 33% decrease. Reported emissions went from 461 tCO₂e to 205 tCO₂e over the same span (down 56%).
What does a site EUI of 3.9 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. 400 S FLOWER ST's 3.9 kBtu/ft² across 916,126 sq ft works out to about 3.6 billion Btu (1,047 MWh-equivalent) in 2025. Its source EUI of 11.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 210 thousand gallons of water for the year.
