Its emissions intensity of 0.7 kgCO₂e/ft² is about 69% below the group average of 2.2 kgCO₂e/ft².
At 80,004 sq ft, it is about 20% below the average floor area of 99,697 sq ft for those buildings. It was built in 1926, 29 years earlier than the group's average year built (1955). Across all 24 jurisdictions BuildingCensus covers, the 267 data center buildings average an ENERGY STAR score of 68 and a site EUI of 504.4 kBtu/ft².
How has Centurylink: East Co's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Centurylink: East Co, covering report years 2015–2025. Site EUI moved from 190.6 kBtu/ft² (2015) to 117.1 kBtu/ft² (2025), a 39% decrease. Reported emissions went from 83 tCO₂e to 53 tCO₂e over the same span (down 36%).
What does a site EUI of 117.1 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. Centurylink: East Co's 117.1 kBtu/ft² across 80,004 sq ft works out to about 9.4 billion Btu (2,746 MWh-equivalent) in 2025. Its source EUI of 327.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,650,568 kWh of electricity for the year.
Which law requires Centurylink: East Co to report its energy use?
Centurylink: East Co 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:566:2025). 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.
