How does Allen Institute For Brain Science (Aibs) 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 145.8 kBtu/ft² is about 18% 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 2.6 kgCO₂e/ft² is about 43% below the group average of 4.6 kgCO₂e/ft².
At 345,290 sq ft, it is about 70% above the average floor area of 202,547 sq ft for those buildings. It was built in 2015, 29 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 Allen Institute For Brain Science (Aibs)'s energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for Allen Institute For Brain Science (Aibs), covering report years 2016–2025. Site EUI moved from 144.5 kBtu/ft² (2016) to 145.8 kBtu/ft² (2025), an 1% increase. Reported emissions went from 971 tCO₂e to 769 tCO₂e over the same span (down 21%).
What does a site EUI of 145.8 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. Allen Institute For Brain Science (Aibs)'s 145.8 kBtu/ft² across 345,290 sq ft works out to about 50.3 billion Btu (14,754 MWh-equivalent) in 2025. Its source EUI of 334.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,965,317 kWh of electricity and 124,411 therms of natural gas for the year.
Which law requires Allen Institute For Brain Science (Aibs) to report its energy use?
Allen Institute For Brain Science (Aibs) 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:50094:2025). 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.
