How does Alaska Marine Lines compare with other distribution center buildings in Seattle?
The latest disclosures cover 38 distribution center buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 42.8 kBtu/ft² is about 57% above the average of 27.3 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is about 15% above the group average of 0.6 kgCO₂e/ft².
At 44,708 sq ft, it is about 29% below the average floor area of 62,568 sq ft for those buildings. It was built in 1971, 4 years later than the group's average year built (1968). Across all 24 jurisdictions BuildingCensus covers, the 4,082 distribution center buildings average an ENERGY STAR score of 65 and a site EUI of 24.2 kBtu/ft².
How has Alaska Marine Lines's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Alaska Marine Lines, covering report years 2015–2025. Site EUI moved from 40.7 kBtu/ft² (2015) to 42.8 kBtu/ft² (2025), an 5% increase. Reported emissions went from 22 tCO₂e to 31 tCO₂e over the same span (up 39%).
What does a site EUI of 42.8 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. Alaska Marine Lines's 42.8 kBtu/ft² across 44,708 sq ft works out to about 1.9 billion Btu (561 MWh-equivalent) in 2025. Its source EUI of 102.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 433,831 kWh of electricity and 4,325 therms of natural gas for the year.
Which law requires Alaska Marine Lines to report its energy use?
Alaska Marine Lines 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:21192:2025). 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.
