At 46,340 sq ft, it is about 31% below the average floor area of 66,769 sq ft for those buildings. It was built in 2001, 25 years later than the group's average year built (1976). Across all 24 jurisdictions BuildingCensus covers, the 2,372 manufacturing/industrial plant buildings average an ENERGY STAR score of 67 and a site EUI of 126.3 kBtu/ft².
How has Seadrunar Properties's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Seadrunar Properties, covering report years 2015–2025. Its ENERGY STAR score went from 3 in 2015 to 33 in 2020 (+30 points); its best year on file was 2019, at 33. Site EUI moved from 52.6 kBtu/ft² (2015) to 46.7 kBtu/ft² (2025), a 11% decrease. Reported emissions went from 14 tCO₂e to 15 tCO₂e over the same span (up 6%).
What does a site EUI of 46.7 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. Seadrunar Properties's 46.7 kBtu/ft² across 46,340 sq ft works out to about 2.2 billion Btu (634 MWh-equivalent) in 2025. Its source EUI of 130.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 754,216 kWh of electricity for the year.
Which law requires Seadrunar Properties to report its energy use?
Seadrunar Properties 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:19489:2025). 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.
