Its site EUI of 121.7 kBtu/ft² is about 14% below the average of 142.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.9 kgCO₂e/ft² is about 32% above the group average of 3.7 kgCO₂e/ft².

At 225,982 sq ft, it is about 67% above the average floor area of 134,952 sq ft for those buildings. It was built in 2004, 12 years later than the group's average year built (1992).

How has ARNOLD PAVILLION's energy performance changed over time?

BuildingCensus holds 10 Seattle disclosures for ARNOLD PAVILLION, covering report years 2015–2024. Its ENERGY STAR score went from 61 in 2015 to 30 in 2023 (-31 points); its best year on file was 2015, at 61. Site EUI moved from 92.7 kBtu/ft² (2015) to 121.7 kBtu/ft² (2024), an 31% increase. Reported emissions went from 616 tCO₂e to 980 tCO₂e over the same span (up 59%).

What does a site EUI of 121.7 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. ARNOLD PAVILLION's 121.7 kBtu/ft² across 225,982 sq ft works out to about 27.5 billion Btu (8,060 MWh-equivalent) in 2024. Its source EUI of 251.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,871,874 kWh of electricity for the year.

Which law requires ARNOLD PAVILLION to report its energy use?

ARNOLD PAVILLION 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 2024 disclosure (source record seattle:656:2024). 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.
