How does 8th & Republican 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. 8th & Republican's ENERGY STAR score of 99 compares with an average of 83 across the 1,652 that report a score; it scores higher than 80% of them and lower than 12%. Its site EUI of 30.6 kBtu/ft² is about 12% below 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 0.7 kgCO₂e/ft² is roughly in line with the group average of 0.7 kgCO₂e/ft².

At 245,889 sq ft, it is about 184% above the average floor area of 86,468 sq ft for those buildings. It was built in 2016, 33 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 8th & Republican's energy performance changed over time?

BuildingCensus holds 10 Seattle disclosures for 8th & Republican, covering report years 2016–2025. Its ENERGY STAR score went from 100 in 2017 to 99 in 2025 (-1 points); its best year on file was 2017, at 100. Site EUI moved from 31.5 kBtu/ft² (2017) to 30.6 kBtu/ft² (2025), a 3% decrease. Reported emissions went from 193 tCO₂e to 160 tCO₂e over the same span (down 17%).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. 8th & Republican's 30.6 kBtu/ft² across 245,889 sq ft works out to about 7.5 billion Btu (2,205 MWh-equivalent) in 2025. Its source EUI of 64.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,181,640 kWh of electricity and 26,185 therms of natural gas for the year.

Which law requires 8th & Republican to report its energy use?

8th & Republican 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:50164:2025). 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.
