How has 700 Dexter Yard Bio Tech Building's energy performance changed over time?
BuildingCensus holds 3 Seattle disclosures for 700 Dexter Yard Bio Tech Building, covering report years 2023–2025. Site EUI moved from 49.8 kBtu/ft² (2023) to 57.8 kBtu/ft² (2025), an 16% increase. Reported emissions went from 540 tCO₂e to 488 tCO₂e over the same span (down 10%).
What does a site EUI of 57.8 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. 700 Dexter Yard Bio Tech Building's 57.8 kBtu/ft² across 716,128 sq ft works out to about 41.4 billion Btu (12,131 MWh-equivalent) in 2025. Its source EUI of 139.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 7,213,012 kWh of electricity and 68,009 therms of natural gas for the year.
Which law requires 700 Dexter Yard Bio Tech Building to report its energy use?
700 Dexter Yard Bio Tech Building 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:50859:2025). 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.
