How does Airport Way Ctr - Bldg A compare with other laboratory buildings in Seattle?
The latest disclosures cover 32 laboratory buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 124.2 kBtu/ft² is about 30% below the average of 178.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.1 kgCO₂e/ft² is about half of the group average of 4.6 kgCO₂e/ft².
At 99,122 sq ft, it is about half of the average floor area of 202,547 sq ft for those buildings. It was built in 1944, 42 years earlier than the group's average year built (1986). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has Airport Way Ctr - Bldg A's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Airport Way Ctr - Bldg A, covering report years 2015–2025. Site EUI moved from 144.8 kBtu/ft² (2015) to 124.2 kBtu/ft² (2025), a 14% decrease. Reported emissions went from 164 tCO₂e to 208 tCO₂e over the same span (up 27%).
What does a site EUI of 124.2 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. Airport Way Ctr - Bldg A's 124.2 kBtu/ft² across 99,122 sq ft works out to about 12.3 billion Btu (3,608 MWh-equivalent) in 2025. Its source EUI of 296.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,779,410 kWh of electricity and 29,327 therms of natural gas for the year.
Which law requires Airport Way Ctr - Bldg A to report its energy use?
Airport Way Ctr - Bldg A 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:785:2025). 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.
