Compliance context
Seattle Energy Benchmarking Ordinance (SMC 22.920)
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.

How does Agc Building & Bank compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Agc Building & Bank's ENERGY STAR score of 84 compares with an average of 76 across the 378 that report a score; it scores higher than 51% of them and lower than 46%. Its site EUI of 46.0 kBtu/ft² is roughly in line with the average of 44.8 kBtu/ft². Its emissions intensity of 0.5 kgCO₂e/ft² is about 36% below the group average of 0.7 kgCO₂e/ft².
At 124,721 sq ft, it is about 37% below the average floor area of 196,452 sq ft for those buildings. It was built in 1971, 6 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has Agc Building & Bank's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Agc Building & Bank, covering report years 2015–2025. Its ENERGY STAR score went from 56 in 2015 to 84 in 2025 (+28 points). Site EUI moved from 111.9 kBtu/ft² (2015) to 46.0 kBtu/ft² (2025), a 59% decrease. Reported emissions went from 350 tCO₂e to 56 tCO₂e over the same span (down 84%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 falls in band B — above median (70–84). 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. Agc Building & Bank's 46.0 kBtu/ft² across 124,721 sq ft works out to about 5.7 billion Btu (1,681 MWh-equivalent) in 2025. Its source EUI of 121.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,522,624 kWh of electricity and 5,436 therms of natural gas for the year.
Which law requires Agc Building & Bank to report its energy use?
Agc Building & Bank 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:604:2025). 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.
