How has South Light Rail Station - Primary's energy performance changed over time?
BuildingCensus holds 4 Seattle disclosures for South Light Rail Station - Primary, covering report years 2022–2025. Site EUI moved from 83.2 kBtu/ft² (2022) to 46.2 kBtu/ft² (2025), a 44% decrease. Reported emissions went from 74 tCO₂e to 41 tCO₂e over the same span (down 45%).
What does a site EUI of 46.2 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. South Light Rail Station - Primary's 46.2 kBtu/ft² across 28,264 sq ft works out to about 1.3 billion Btu (383 MWh-equivalent) in 2025. Its source EUI of 129.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,072,215 kWh of electricity for the year.
Which law requires South Light Rail Station - Primary to report its energy use?
