At 175,918 sq ft, it is about 13% below the average floor area of 202,547 sq ft for those buildings. It was built in 2008, 22 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 Gilead Sciences Bldg. (Alexandria R.e.) Econ. Uni's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Gilead Sciences Bldg. (Alexandria R.e.) Econ. Uni, covering report years 2015–2025. Site EUI moved from 206.9 kBtu/ft² (2015) to 160.4 kBtu/ft² (2025), a 22% decrease. Reported emissions went from 552 tCO₂e to 539 tCO₂e over the same span (down 2%).
What does a site EUI of 160.4 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. Gilead Sciences Bldg. (Alexandria R.e.) Econ. Uni's 160.4 kBtu/ft² across 175,918 sq ft works out to about 28.2 billion Btu (8,270 MWh-equivalent) in 2025. Its source EUI of 310.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,757,572 kWh of electricity and 92,229 therms of natural gas for the year.
Which law requires Gilead Sciences Bldg. (Alexandria R.e.) Econ. Uni to report its energy use?
Gilead Sciences Bldg. (Alexandria R.e.) Econ. Uni 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:602:2025). 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.
