How has 1700 Seventh Building's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 1700 Seventh Building, covering report years 2015–2025. Its ENERGY STAR score went from 88 in 2015 to 87 in 2021 (-1 points); its best year on file was 2016, at 90. Site EUI moved from 58.2 kBtu/ft² (2015) to 35.8 kBtu/ft² (2025), a 38% decrease. Reported emissions went from 341 tCO₂e to 113 tCO₂e over the same span (down 67%).
What does a site EUI of 35.8 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. 1700 Seventh Building's 35.8 kBtu/ft² across 747,747 sq ft works out to about 26.8 billion Btu (7,845 MWh-equivalent) in 2025. Its source EUI of 100.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5,783,789 kWh of electricity and 9 therms of natural gas for the year.
Which law requires 1700 Seventh Building to report its energy use?
1700 Seventh 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:329:2025). 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.
