How does Columbia Place compare with other multifamily housing buildings in Seattle?
The latest disclosures cover 1,971 multifamily housing buildings in Seattle, out of 3,871 buildings citywide. Columbia Place's ENERGY STAR score of 58 compares with an average of 83 across the 1,652 that report a score; it scores higher than 12% of them and lower than 88%. Its site EUI of 32.3 kBtu/ft² is roughly in line with the average of 34.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.2 kgCO₂e/ft² is about 73% below the group average of 0.7 kgCO₂e/ft².
At 52,228 sq ft, it is about 40% below the average floor area of 86,468 sq ft for those buildings. Its 1983 construction date is close to the group's average year built (1983). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has Columbia Place's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Columbia Place, covering report years 2015–2025. Its ENERGY STAR score went from 48 in 2015 to 58 in 2025 (+10 points); its best year on file was 2023, at 73. Site EUI moved from 30.9 kBtu/ft² (2015) to 32.3 kBtu/ft² (2025), an 5% increase. Reported emissions went from 9 tCO₂e to 10 tCO₂e over the same span (up 3%).
What does an ENERGY STAR score of 58 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 58 means the building performs better than about 58% of its national peers. BuildingCensus bands the score into report-card grades; 58 falls in band C — below median (55–69). It sits 17 points below 75, the threshold for ENERGY STAR certification. 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. Columbia Place's 32.3 kBtu/ft² across 52,228 sq ft works out to about 1.7 billion Btu (494 MWh-equivalent) in 2025. Its source EUI of 90.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 494,640 kWh of electricity for the year.
Which law requires Columbia Place to report its energy use?
Columbia Place 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:22136:2025). 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.
