Its emissions intensity of 0.3 kgCO₂e/ft² is about 73% below the group average of 1.1 kgCO₂e/ft².
At 25,460 sq ft, it is about half of the average floor area of 55,708 sq ft for those buildings. Its 1952 construction date is close to the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 1,327 other buildings average an ENERGY STAR score of 60 and a site EUI of 63.3 kBtu/ft².
How has CENTURYLINK: COIN OFFICE's energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for CENTURYLINK: COIN OFFICE, covering report years 2015–2024. Site EUI moved from 111.4 kBtu/ft² (2015) to 50.2 kBtu/ft² (2024), a 55% decrease. Reported emissions went from 5 tCO₂e to 2 tCO₂e over the same span (down 55%).
What does a site EUI of 50.2 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. CENTURYLINK: COIN OFFICE's 50.2 kBtu/ft² across 25,460 sq ft works out to about 1.3 billion Btu (375 MWh-equivalent) in 2024. Its source EUI of 140.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 121,000 kWh of electricity for the year.
Which law requires CENTURYLINK: COIN OFFICE to report its energy use?
CENTURYLINK: COIN OFFICE 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 2024 disclosure (source record seattle:24950:2024). 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.
