How does Salmon Bay Fisheries Bldg compare with other office buildings in Seattle?

The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Salmon Bay Fisheries Bldg's ENERGY STAR score of 77 compares with an average of 76 across the 378 that report a score; it scores higher than 36% of them and lower than 62%. Its site EUI of 25.2 kBtu/ft² is about 44% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 80% below the group average of 0.7 kgCO₂e/ft².

At 22,365 sq ft, it is about 89% below the average floor area of 196,452 sq ft for those buildings. It was built in 1979, 14 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 Salmon Bay Fisheries Bldg's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Salmon Bay Fisheries Bldg, covering report years 2015–2025. Its ENERGY STAR score went from 95 in 2015 to 77 in 2025 (-18 points); its best year on file was 2015, at 95. Site EUI moved from 20.1 kBtu/ft² (2015) to 25.2 kBtu/ft² (2025), an 25% increase. Reported emissions went from 3 tCO₂e to 3 tCO₂e over the same span (up 25%).

What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. Salmon Bay Fisheries Bldg's 25.2 kBtu/ft² across 22,365 sq ft works out to about 0.6 billion Btu (165 MWh-equivalent) in 2025. Its source EUI of 70.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 159,345 kWh of electricity for the year.

Which law requires Salmon Bay Fisheries Bldg to report its energy use?

Salmon Bay Fisheries Bldg 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:22607:2025). 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.
