How has 1300 Alki Condominium's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 1300 Alki Condominium, covering report years 2015–2025. Site EUI moved from 37.1 kBtu/ft² (2015) to 32.5 kBtu/ft² (2025), a 12% decrease. Reported emissions went from 30 tCO₂e to 27 tCO₂e over the same span (down 13%).
What does a site EUI of 32.5 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. 1300 Alki Condominium's 32.5 kBtu/ft² across 23,821 sq ft works out to about 0.8 billion Btu (227 MWh-equivalent) in 2025. Its source EUI of 55.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 86,558 kWh of electricity and 4,790 therms of natural gas for the year.
Which law requires 1300 Alki Condominium to report its energy use?
