How does Seattle Design Center compare with other buildings in Seattle?
The latest disclosures cover 3,871 benchmarked buildings in Seattle. Its site EUI of 10.2 kBtu/ft² is about 79% below the average of 47.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 62% below the group average of 1.0 kgCO₂e/ft².
At 156,188 sq ft, it is about 39% above the average floor area of 112,467 sq ft for those buildings. Its 1973 construction date is close to the group's average year built (1975).
How has Seattle Design Center's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Seattle Design Center, covering report years 2015–2025. Its ENERGY STAR score went from 74 in 2015 to 47 in 2018 (-27 points); its best year on file was 2015, at 74. Site EUI moved from 43.9 kBtu/ft² (2015) to 10.2 kBtu/ft² (2025), a 77% decrease. Reported emissions went from 48 tCO₂e to 60 tCO₂e over the same span (up 27%).
What does a site EUI of 10.2 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. Seattle Design Center's 10.2 kBtu/ft² across 156,188 sq ft works out to about 1.6 billion Btu (467 MWh-equivalent) in 2025. Its source EUI of 16.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 155,086 kWh of electricity and 10,783 therms of natural gas for the year.
Which law requires Seattle Design Center to report its energy use?
Seattle Design 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:793:2025). 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.
