The latest disclosures cover 3,871 benchmarked buildings in Seattle. Its site EUI of 36.8 kBtu/ft² is about 23% below the average of 47.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.2 kgCO₂e/ft² is about 79% below the group average of 1.0 kgCO₂e/ft².
At 21,462 sq ft, it is about 81% below the average floor area of 112,467 sq ft for those buildings. It was built in 1923, 52 years earlier than the group's average year built (1975). Across all 24 jurisdictions BuildingCensus covers, the 27 energy/power station buildings average an ENERGY STAR score of 1 and a site EUI of 891.5 kBtu/ft².
How has Seattle City Light North Substation's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Seattle City Light North Substation, covering report years 2015–2025. Site EUI moved from 42.7 kBtu/ft² (2015) to 36.8 kBtu/ft² (2025), a 14% decrease. Reported emissions went from 6 tCO₂e to 6 tCO₂e over the same span (down 6%).
What does a site EUI of 36.8 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. Seattle City Light North Substation's 36.8 kBtu/ft² across 21,462 sq ft works out to about 0.8 billion Btu (231 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 314,296 kWh of electricity for the year.
Which law requires Seattle City Light North Substation to report its energy use?
Seattle City Light North Substation 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:19697:2025). 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.
