How has 20351 PRAIRIE ST's energy performance changed over time?
BuildingCensus holds 8 Los Angeles disclosures for 20351 PRAIRIE ST, covering report years 2018–2025. Site EUI moved from 1.8 kBtu/ft² (2018) to 1.9 kBtu/ft² (2025), an 6% increase. Reported emissions went from 4 tCO₂e to 3 tCO₂e over the same span (down 6%).
What does a site EUI of 1.9 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. 20351 PRAIRIE ST's 1.9 kBtu/ft² across 32,480 sq ft works out to about 0.1 billion Btu (18 MWh-equivalent) in 2025. Its source EUI of 3.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 70 thousand gallons of water for the year.
