How does 1201 Eastlake Ave E (Zymogenetics) 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 222.0 kBtu/ft² is about 24% 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 6.4 kgCO₂e/ft² is about 38% above the group average of 4.6 kgCO₂e/ft².
At 169,785 sq ft, it is about 16% below the average floor area of 202,547 sq ft for those buildings. It was built in 1920, 66 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 1201 Eastlake Ave E (Zymogenetics)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 1201 Eastlake Ave E (Zymogenetics), covering report years 2015–2025. Site EUI moved from 199.9 kBtu/ft² (2015) to 222.0 kBtu/ft² (2025), an 11% increase. Reported emissions went from 469 tCO₂e to 717 tCO₂e over the same span (up 53%).
What does a site EUI of 222.0 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. 1201 Eastlake Ave E (Zymogenetics)'s 222.0 kBtu/ft² across 169,785 sq ft works out to about 37.7 billion Btu (11,047 MWh-equivalent) in 2025. Its source EUI of 430.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,720,545 kWh of electricity and 122,874 therms of natural gas for the year.
Which law requires 1201 Eastlake Ave E (Zymogenetics) to report its energy use?
1201 Eastlake Ave E (Zymogenetics) 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:603:2025). 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.
