The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 44.7 kBtu/ft² is roughly in line with the average of 44.8 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 half of the group average of 0.7 kgCO₂e/ft².
At 338,063 sq ft, it is about 72% above the average floor area of 196,452 sq ft for those buildings. It was built in 2002, 37 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has Stanford Center Offices (Sps-District)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Stanford Center Offices (Sps-District), covering report years 2015–2025. Site EUI moved from 62.5 kBtu/ft² (2015) to 44.7 kBtu/ft² (2025), a 28% decrease. Reported emissions went from 238 tCO₂e to 128 tCO₂e over the same span (down 46%).
What does a site EUI of 44.7 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. Stanford Center Offices (Sps-District)'s 44.7 kBtu/ft² across 338,063 sq ft works out to about 15.1 billion Btu (4,429 MWh-equivalent) in 2025. Its source EUI of 121.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,447,015 kWh of electricity and 7,915 therms of natural gas for the year.
Which law requires Stanford Center Offices (Sps-District) to report its energy use?
Stanford Center Offices (Sps-District) 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:854:2025). 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.
