What does a site EUI of 45.1 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. Exhibition Hall - Seattle Center's 45.1 kBtu/ft² across 52,000 sq ft works out to about 2.3 billion Btu (687 MWh-equivalent) in 2025. Its source EUI of 91.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 381,202 kWh of electricity for the year.
Which law requires Exhibition Hall - Seattle Center to report its energy use?
