How does Hanford Cntr compare with other manufacturing/industrial plant buildings in Seattle?
The latest disclosures cover 14 manufacturing/industrial plant buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 33.1 kBtu/ft² is about 25% below the average of 44.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.1 kgCO₂e/ft² is roughly in line with the group average of 1.1 kgCO₂e/ft².
At 35,310 sq ft, it is about half of the average floor area of 66,769 sq ft for those buildings. It was built in 1952, 24 years earlier 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 Hanford Cntr's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Hanford Cntr, covering report years 2015–2025. Site EUI moved from 59.8 kBtu/ft² (2015) to 33.1 kBtu/ft² (2025), a 45% decrease. Reported emissions went from 50 tCO₂e to 37 tCO₂e over the same span (down 26%).
What does a site EUI of 33.1 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. Hanford Cntr's 33.1 kBtu/ft² across 35,310 sq ft works out to about 1.2 billion Btu (343 MWh-equivalent) in 2025. Its source EUI of 59.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 147,149 kWh of electricity and 6,574 therms of natural gas for the year.
Which law requires Hanford Cntr to report its energy use?
Hanford Cntr 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:24959:2025). 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.
