How does Pier 70 compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 108.6 kBtu/ft² is about 142% above the average of 44.8 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 1.9 kgCO₂e/ft² is about 177% above the group average of 0.7 kgCO₂e/ft².
At 116,430 sq ft, it is about 41% below the average floor area of 196,452 sq ft for those buildings. It was built in 1902, 63 years earlier than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has Pier 70's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Pier 70, covering report years 2015–2025. Its ENERGY STAR score went from 51 in 2015 to 33 in 2021 (-18 points); its best year on file was 2015, at 51. Site EUI moved from 114.8 kBtu/ft² (2015) to 108.6 kBtu/ft² (2025), a 5% decrease. Reported emissions went from 253 tCO₂e to 226 tCO₂e over the same span (down 11%).
What does a site EUI of 108.6 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. Pier 70's 108.6 kBtu/ft² across 116,430 sq ft works out to about 12.6 billion Btu (3,706 MWh-equivalent) in 2025. Its source EUI of 255.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,761,328 kWh of electricity and 32,274 therms of natural gas for the year.
Which law requires Pier 70 to report its energy use?
Pier 70 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:748:2025). 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.
