What does a site EUI of 1673.6 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. Data Center, 2020 5TH AVE's 1673.6 kBtu/ft² across 82,149 sq ft works out to about 137.5 billion Btu (40,293 MWh-equivalent) in 2025. Its source EUI of 4686.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 29,431,120 kWh of electricity for the year.
Which law requires Data Center, 2020 5TH AVE to report its energy use?
Data Center, 2020 5TH AVE 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:49780:2025). 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.
