Concord Condominium

How does Concord Condominium 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. Concord Condominium's ENERGY STAR score of 11 compares with an average of 83 across the 1,652 that report a score; it scores higher than 1% of them and lower than 99%. Its site EUI of 89.6 kBtu/ft² is about 157% above the average of 34.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 3.5 kgCO₂e/ft² is about 401% above the group average of 0.7 kgCO₂e/ft².

At 219,874 sq ft, it is about 154% above the average floor area of 86,468 sq ft for those buildings. It was built in 1999, 16 years later than 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 Concord Condominium's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Concord Condominium, covering report years 2015–2025. Its ENERGY STAR score went from 16 in 2015 to 11 in 2025 (-5 points); its best year on file was 2024, at 41. Site EUI moved from 58.6 kBtu/ft² (2015) to 89.6 kBtu/ft² (2025), an 53% increase. Reported emissions went from 366 tCO₂e to 728 tCO₂e over the same span (up 99%).

What does an ENERGY STAR score of 11 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 11 means the building performs better than about 11% of its national peers. BuildingCensus bands the score into report-card grades; 11 falls in band D — lowest band (1–54). It sits 64 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. Concord Condominium's 89.6 kBtu/ft² across 219,874 sq ft works out to about 19.7 billion Btu (5,774 MWh-equivalent) in 2025. Its source EUI of 139.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,575,003 kWh of electricity and 131,842 therms of natural gas for the year.

Which law requires Concord Condominium to report its energy use?

Concord Condominium 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:20762:2025). 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.
