Its emissions intensity of 0.1 kgCO₂e/ft² is about 89% below the group average of 0.7 kgCO₂e/ft².
At 350,310 sq ft, it is about 78% above the average floor area of 196,452 sq ft for those buildings. It was built in 1916, 49 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 2601 ELLIOTT AVE's energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for 2601 ELLIOTT AVE, covering report years 2015–2024. Its ENERGY STAR score went from 89 in 2015 to 1 in 2022 (-88 points); its best year on file was 2016, at 90. Site EUI moved from 54.7 kBtu/ft² (2015) to 13.7 kBtu/ft² (2024), a 75% decrease. Reported emissions went from 94 tCO₂e to 27 tCO₂e over the same span (down 71%).
What does a site EUI of 13.7 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. 2601 ELLIOTT AVE's 13.7 kBtu/ft² across 350,310 sq ft works out to about 4.8 billion Btu (1,407 MWh-equivalent) in 2024. Its source EUI of 38.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,363,801 kWh of electricity for the year.
Which law requires 2601 ELLIOTT AVE to report its energy use?
2601 ELLIOTT AVE 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 2024 disclosure (source record seattle:398:2024). 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.
