What does a site EUI of 37.3 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 Seattle College - Cascade Hall's 37.3 kBtu/ft² across 57,333 sq ft works out to about 2.1 billion Btu (627 MWh-equivalent) in 2025. Its source EUI of 100.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 591,422 kWh of electricity and 1,198 therms of natural gas for the year.
Which law requires South Seattle College - Cascade Hall to report its energy use?
