How has Samson Tug & Barge's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Samson Tug & Barge, covering report years 2015–2025. Its ENERGY STAR score went from 11 in 2015 to 29 in 2025 (+18 points); its best year on file was 2023, at 29. Site EUI moved from 33.2 kBtu/ft² (2015) to 27.2 kBtu/ft² (2025), a 18% decrease. Reported emissions went from 4 tCO₂e to 3 tCO₂e over the same span (down 17%).
What does an ENERGY STAR score of 29 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 29 means the building performs better than about 29% of its national peers. BuildingCensus bands the score into report-card grades; 29 falls in band D — lowest band (1–54). It sits 46 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. Samson Tug & Barge's 27.2 kBtu/ft² across 22,000 sq ft works out to about 0.6 billion Btu (175 MWh-equivalent) in 2025. Its source EUI of 76.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 175,174 kWh of electricity for the year.
Which law requires Samson Tug & Barge to report its energy use?
Samson Tug & Barge 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:21902:2025). 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.
