Its site EUI of 37.9 kBtu/ft² is about 36% below the average of 59.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.2 kgCO₂e/ft² is about 12% above the group average of 1.1 kgCO₂e/ft².
At 21,036 sq ft, it is about 62% below the average floor area of 55,708 sq ft for those buildings. It was built in 1988, 36 years later than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 1,327 other buildings average an ENERGY STAR score of 60 and a site EUI of 63.3 kBtu/ft².
How has Arboretum Court Ii's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Arboretum Court Ii, covering report years 2015–2025. Site EUI moved from 125.0 kBtu/ft² (2015) to 37.9 kBtu/ft² (2025), a 70% decrease. Reported emissions went from 78 tCO₂e to 39 tCO₂e over the same span (down 50%).
What does a site EUI of 37.9 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. Arboretum Court Ii's 37.9 kBtu/ft² across 21,036 sq ft works out to about 0.8 billion Btu (234 MWh-equivalent) in 2025. Its source EUI of 67.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 146,849 kWh of electricity and 7,040 therms of natural gas for the year.
Which law requires Arboretum Court Ii to report its energy use?
Arboretum Court Ii 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:26994:2025). 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.
