How has Taiyo Condominium's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Taiyo Condominium, covering report years 2015–2025. Site EUI moved from 21.4 kBtu/ft² (2015) to 20.2 kBtu/ft² (2025), a 6% decrease. Reported emissions went from 3 tCO₂e to 3 tCO₂e over the same span (down 6%).
What does a site EUI of 20.2 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. Taiyo Condominium's 20.2 kBtu/ft² across 24,192 sq ft works out to about 0.5 billion Btu (143 MWh-equivalent) in 2025. Its source EUI of 56.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 143,446 kWh of electricity for the year.
Which law requires Taiyo Condominium to report its energy use?
Taiyo 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. The record shown here is the report-year 2025 disclosure (source record seattle:23166:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
