How does Queen Anne Plaza compare with other office buildings in Seattle?

The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Queen Anne Plaza's ENERGY STAR score of 100 compares with an average of 76 across the 378 that report a score; it scores higher than 96% of them. Its site EUI of 0.8 kBtu/ft² is about 98% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 86,995 sq ft, it is about 56% below the average floor area of 196,452 sq ft for those buildings. It was built in 1985, 20 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 Queen Anne Plaza's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Queen Anne Plaza, covering report years 2015–2025. Its ENERGY STAR score went from 78 in 2015 to 100 in 2025 (+22 points); its best year on file was 2024, at 100. Site EUI moved from 54.3 kBtu/ft² (2015) to 0.8 kBtu/ft² (2025), a 99% decrease. Reported emissions went from 18 tCO₂e to 0 tCO₂e over the same span (down 99%).

What does an ENERGY STAR score of 100 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Seattle, 69% of scored buildings are at 75 or above.

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. Queen Anne Plaza's 0.8 kBtu/ft² across 86,995 sq ft works out to about 0.1 billion Btu (20 MWh-equivalent) in 2025. Its source EUI of 2.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 13,572 kWh of electricity for the year.

Which law requires Queen Anne Plaza to report its energy use?

Queen Anne Plaza 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:492:2025). 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.
