How has Alii-Kai Condominium's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Alii-Kai Condominium, covering report years 2015–2025. Site EUI moved from 20.5 kBtu/ft² (2015) to 19.0 kBtu/ft² (2025), a 7% decrease. Reported emissions went from 3 tCO₂e to 2 tCO₂e over the same span (down 9%).
What does a site EUI of 19.0 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. Alii-Kai Condominium's 19.0 kBtu/ft² across 22,445 sq ft works out to about 0.4 billion Btu (125 MWh-equivalent) in 2025. Its source EUI of 53.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 116,806 kWh of electricity for the year.
Which law requires Alii-Kai Condominium to report its energy use?
Alii-Kai Condominium reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results.
