How does Pacific Northwest Research Lab 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 273.1 kBtu/ft² is about 53% above the average of 178.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 11.2 kgCO₂e/ft² is about 143% above the group average of 4.6 kgCO₂e/ft².
At 45,780 sq ft, it is about 77% below the average floor area of 202,547 sq ft for those buildings. Its 1988 construction date is close to 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 Pacific Northwest Research Lab's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Pacific Northwest Research Lab, covering report years 2015–2025. Site EUI moved from 227.2 kBtu/ft² (2015) to 273.1 kBtu/ft² (2025), an 20% increase. Reported emissions went from 431 tCO₂e to 420 tCO₂e over the same span (down 3%).
What does a site EUI of 273.1 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. Pacific Northwest Research Lab's 273.1 kBtu/ft² across 45,780 sq ft works out to about 12.5 billion Btu (3,664 MWh-equivalent) in 2025. Its source EUI of 559.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,597,190 kWh of electricity and 469 therms of natural gas for the year.
Which law requires Pacific Northwest Research Lab to report its energy use?
Pacific Northwest Research Lab 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:21364:2025). 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.
