How does Canal Boiler Works compare with other other buildings in Seattle?
The latest disclosures cover 45 other buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 19.7 kBtu/ft² is about 67% below the average of 59.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 65% below the group average of 1.1 kgCO₂e/ft².
At 32,100 sq ft, it is about 42% below the average floor area of 55,708 sq ft for those buildings. It was built in 1910, 42 years earlier than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 1,327 other buildings average an ENERGY STAR score of 60 and a site EUI of 63.3 kBtu/ft².
How has Canal Boiler Works's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Canal Boiler Works, covering report years 2015–2025. Site EUI moved from 17.5 kBtu/ft² (2015) to 19.7 kBtu/ft² (2025), an 13% increase. Reported emissions went from 16 tCO₂e to 12 tCO₂e over the same span (down 23%).
What does a site EUI of 19.7 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. Canal Boiler Works's 19.7 kBtu/ft² across 32,100 sq ft works out to about 0.6 billion Btu (185 MWh-equivalent) in 2025. Its source EUI of 43.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 123,928 kWh of electricity and 2,084 therms of natural gas for the year.
Which law requires Canal Boiler Works to report its energy use?
Canal Boiler Works 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:24100:2025). 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.
