Its emissions intensity of 4.8 kgCO₂e/ft² is roughly in line with the group average of 4.6 kgCO₂e/ft².
At 258,505 sq ft, it is about 28% above the average floor area of 202,547 sq ft for those buildings. It was built in 2003, 17 years later 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 401 Terry Ave (Institute For System Biology)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 401 Terry Ave (Institute For System Biology), covering report years 2015–2025. Site EUI moved from 228.1 kBtu/ft² (2015) to 229.5 kBtu/ft² (2025), an 1% increase. Reported emissions went from 937 tCO₂e to 841 tCO₂e over the same span (down 10%).
What does a site EUI of 229.5 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. 401 Terry Ave (Institute For System Biology)'s 229.5 kBtu/ft² across 258,505 sq ft works out to about 59.3 billion Btu (17,387 MWh-equivalent) in 2025. Its source EUI of 503.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 7,665,451 kWh of electricity and 139,000 therms of natural gas for the year.
Which law requires 401 Terry Ave (Institute For System Biology) to report its energy use?
401 Terry Ave (Institute For System Biology) 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:470:2025). 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.
