Its site EUI of 43.2 kBtu/ft² is about 24% 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 1.0 kgCO₂e/ft² is about 49% above the group average of 0.7 kgCO₂e/ft².
At 145,812 sq ft, it is about 69% above the average floor area of 86,468 sq ft for those buildings. It was built in 2007, 24 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 Brix's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Brix, covering report years 2015–2025. Site EUI moved from 41.3 kBtu/ft² (2015) to 43.2 kBtu/ft² (2025), an 5% increase. Reported emissions went from 121 tCO₂e to 130 tCO₂e over the same span (up 7%).
What does a site EUI of 43.2 kBtu/ft² mean?
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. Brix's 43.2 kBtu/ft² across 145,812 sq ft works out to about 6.3 billion Btu (1,846 MWh-equivalent) in 2025. Its source EUI of 91.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 962,646 kWh of electricity and 20,917 therms of natural gas for the year.
Which law requires Brix to report its energy use?
Brix 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:20210:2025). 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.
