Its site EUI of 68.0 kBtu/ft² is about 14% above the average of 59.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 65% below the group average of 1.1 kgCO₂e/ft².
At 41,022 sq ft, it is about 26% below the average floor area of 55,708 sq ft for those buildings. It was built in 1921, 31 years earlier than 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: Parkway Co's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Centurylink: Parkway Co, covering report years 2015–2025. Site EUI moved from 94.0 kBtu/ft² (2015) to 68.0 kBtu/ft² (2025), a 28% decrease. Reported emissions went from 22 tCO₂e to 16 tCO₂e over the same span (down 28%).
What does a site EUI of 68.0 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: Parkway Co's 68.0 kBtu/ft² across 41,022 sq ft works out to about 2.8 billion Btu (818 MWh-equivalent) in 2025. Its source EUI of 190.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 817,759 kWh of electricity for the year.
Which law requires Centurylink: Parkway Co to report its energy use?
Centurylink: Parkway 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:23320:2025). 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.
