How does Georgetown Steam Plant 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 4.3 kBtu/ft² is about 93% 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 0.0 kgCO₂e/ft² is about 97% below the group average of 1.1 kgCO₂e/ft².
At 39,212 sq ft, it is about 30% below the average floor area of 55,708 sq ft for those buildings. It was built in 1906, 46 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 Georgetown Steam Plant's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Georgetown Steam Plant, covering report years 2015–2025. Site EUI moved from 19.7 kBtu/ft² (2015) to 4.3 kBtu/ft² (2025), a 78% decrease. Reported emissions went from 5 tCO₂e to 1 tCO₂e over the same span (down 78%).
What does a site EUI of 4.3 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. Georgetown Steam Plant's 4.3 kBtu/ft² across 39,212 sq ft works out to about 0.2 billion Btu (49 MWh-equivalent) in 2025. Its source EUI of 12.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 49,945 kWh of electricity for the year.
Which law requires Georgetown Steam Plant to report its energy use?
Georgetown Steam Plant 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:43948:2025). 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.
