How does Climate Pledge Arena compare with other buildings in Seattle?
The latest disclosures cover 3,871 benchmarked buildings in Seattle. Its site EUI of 94.3 kBtu/ft² is about twice the average of 47.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.6 kgCO₂e/ft² is about half of the group average of 1.0 kgCO₂e/ft².
At 932,000 sq ft, it is about 729% above the average floor area of 112,467 sq ft for those buildings. It was built in 1962, 13 years earlier than the group's average year built (1975).
How has Climate Pledge Arena's energy performance changed over time?
BuildingCensus holds 4 Seattle disclosures for Climate Pledge Arena, covering report years 2022–2025. Site EUI moved from 120.2 kBtu/ft² (2022) to 94.3 kBtu/ft² (2025), a 22% decrease. Reported emissions went from 650 tCO₂e to 510 tCO₂e over the same span (down 22%).
What does a site EUI of 94.3 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. Climate Pledge Arena's 94.3 kBtu/ft² across 932,000 sq ft works out to about 87.9 billion Btu (25,757 MWh-equivalent) in 2025. Its source EUI of 263.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 25,745,620 kWh of electricity for the year.
Which law requires Climate Pledge Arena to report its energy use?
Climate Pledge Arena 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:103:2025). 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.
