Compliance context
Seattle Energy Benchmarking Ordinance (SMC 22.920)
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.

How does 2345 Eastlake compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. 2345 Eastlake's ENERGY STAR score of 67 compares with an average of 76 across the 378 that report a score; it scores higher than 23% of them and lower than 76%. Its site EUI of 57.1 kBtu/ft² is about 27% 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 0.3 kgCO₂e/ft² is about half of the group average of 0.7 kgCO₂e/ft².
At 57,132 sq ft, it is about 71% below the average floor area of 196,452 sq ft for those buildings. It was built in 2000, 35 years later 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 2345 Eastlake's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 2345 Eastlake, covering report years 2015–2025. Its ENERGY STAR score went from 61 in 2015 to 67 in 2025 (+6 points); its best year on file was 2020, at 86. Site EUI moved from 67.8 kBtu/ft² (2015) to 57.1 kBtu/ft² (2025), a 16% decrease. Reported emissions went from 13 tCO₂e to 11 tCO₂e over the same span (down 16%).
What does an ENERGY STAR score of 67 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. In Seattle, 69% of scored buildings are at 75 or above.
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. 2345 Eastlake's 57.1 kBtu/ft² across 57,132 sq ft works out to about 3.3 billion Btu (956 MWh-equivalent) in 2025. Its source EUI of 160.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 564,375 kWh of electricity for the year.
Which law requires 2345 Eastlake to report its energy use?
2345 Eastlake 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:23674:2025). 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.
