How does 660 WEST OLYMPIC PLACE CONDOMINIUM compare with other multifamily LR (1-4) buildings in Seattle?
The latest disclosures cover 53 multifamily LR (1-4) buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 57.4 kBtu/ft² is about 43% above the average of 40.1 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 1.8 kgCO₂e/ft² is about twice the group average of 0.9 kgCO₂e/ft².
At 21,754 sq ft, it is about half of the average floor area of 45,933 sq ft for those buildings. It was built in 2000, 24 years later than the group's average year built (1976).
How has 660 WEST OLYMPIC PLACE CONDOMINIUM's energy performance changed over time?
BuildingCensus holds 9 Seattle disclosures for 660 WEST OLYMPIC PLACE CONDOMINIUM, covering report years 2015–2023. Site EUI moved from 61.9 kBtu/ft² (2015) to 57.4 kBtu/ft² (2023), a 7% decrease. Reported emissions went from 39 tCO₂e to 35 tCO₂e over the same span (down 12%).
What does a site EUI of 57.4 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. 660 WEST OLYMPIC PLACE CONDOMINIUM's 57.4 kBtu/ft² across 21,754 sq ft works out to about 1.2 billion Btu (366 MWh-equivalent) in 2023. Its source EUI of 106.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 148,375 kWh of electricity and 5,958 therms of natural gas for the year.
Which law requires 660 WEST OLYMPIC PLACE CONDOMINIUM to report its energy use?
660 WEST OLYMPIC PLACE 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 2023 disclosure (source record seattle:23759:2023). 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.
