How does Seattle Convention Center compare with other buildings in Seattle?
The latest disclosures cover 3,871 benchmarked buildings in Seattle. Its site EUI of 58.1 kBtu/ft² is about 22% above 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 1.9 kgCO₂e/ft² is about twice the group average of 1.0 kgCO₂e/ft².
At 1,842,925 sq ft, it is about 1539% above the average floor area of 112,467 sq ft for those buildings. It was built in 1990, 15 years later than the group's average year built (1975).
How has Seattle Convention Center's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Seattle Convention Center, covering report years 2015–2025. Site EUI moved from 72.0 kBtu/ft² (2015) to 58.1 kBtu/ft² (2025), a 19% decrease. Reported emissions went from 1,789 tCO₂e to 2,225 tCO₂e over the same span (up 24%).
What does a site EUI of 58.1 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. Seattle Convention Center's 58.1 kBtu/ft² across 1,842,925 sq ft works out to about 107.1 billion Btu (31,380 MWh-equivalent) in 2025. Its source EUI of 127.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 12,365,950 kWh of electricity and 16,527 therms of natural gas for the year.
Which law requires Seattle Convention Center to report its energy use?
Seattle Convention Center 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:435:2025). 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.
