Brookdale West Seattle

How does Brookdale West Seattle compare with other mixed use property buildings in Seattle?

The latest disclosures cover 157 mixed use property buildings in Seattle, out of 3,871 buildings citywide. Brookdale West Seattle's ENERGY STAR score of 92 compares with an average of 74 across the 29 that report a score; it scores higher than 69% of them and lower than 24%. Its site EUI of 36.5 kBtu/ft² is about half of the average of 68.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.6 kgCO₂e/ft² is about 60% below the group average of 1.4 kgCO₂e/ft².

At 106,976 sq ft, it is about 35% below the average floor area of 165,352 sq ft for those buildings. It was built in 2003, 35 years later than the group's average year built (1968). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².

How has Brookdale West Seattle's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Brookdale West Seattle, covering report years 2015–2025. Its ENERGY STAR score went from 42 in 2015 to 92 in 2025 (+50 points); its best year on file was 2021, at 92. Site EUI moved from 43.5 kBtu/ft² (2015) to 36.5 kBtu/ft² (2025), a 16% decrease. Reported emissions went from 70 tCO₂e to 55 tCO₂e over the same span (down 22%).

What does an ENERGY STAR score of 92 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: a score of 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Brookdale West Seattle's 36.5 kBtu/ft² across 106,976 sq ft works out to about 3.9 billion Btu (1,144 MWh-equivalent) in 2025. Its source EUI of 89.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 831,668 kWh of electricity and 7,417 therms of natural gas for the year.

Which law requires Brookdale West Seattle to report its energy use?

Brookdale West Seattle 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:20445:2025). 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.
