How does Parkview & Waterside Campus compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 70.5 kBtu/ft² is about 57% above the average of 44.8 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.7 kgCO₂e/ft² is roughly in line with the group average of 0.7 kgCO₂e/ft².
At 404,916 sq ft, it is about twice the average floor area of 196,452 sq ft for those buildings. It was built in 2001, 36 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 Parkview & Waterside Campus's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Parkview & Waterside Campus, covering report years 2015–2025. Site EUI moved from 94.1 kBtu/ft² (2018) to 70.5 kBtu/ft² (2025), a 25% decrease. Reported emissions went from 175 tCO₂e to 136 tCO₂e over the same span (down 22%).
What does a site EUI of 70.5 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. Parkview & Waterside Campus's 70.5 kBtu/ft² across 404,916 sq ft works out to about 28.5 billion Btu (8,366 MWh-equivalent) in 2025. Its source EUI of 184.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,439,543 kWh of electricity and 13,810 therms of natural gas for the year.
Which law requires Parkview & Waterside Campus to report its energy use?
Parkview & Waterside Campus 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:50383:2025). 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.
