Amazon Block 18's ENERGY STAR score of 96 compares with an average of 76 across the 378 that report a score; it scores higher than 88% of them and lower than 10%. Its site EUI of 36.2 kBtu/ft² is about 19% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 39% below the group average of 0.7 kgCO₂e/ft².
At 556,007 sq ft, it is about 183% above the average floor area of 196,452 sq ft for those buildings. It was built in 2020, 55 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 Amazon Block 18's energy performance changed over time?
BuildingCensus holds 4 Seattle disclosures for Amazon Block 18, covering report years 2022–2025. Its ENERGY STAR score went from 88 in 2022 to 96 in 2025 (+8 points); its best year on file was 2024, at 96. Site EUI moved from 50.4 kBtu/ft² (2022) to 36.2 kBtu/ft² (2025), a 28% decrease. Reported emissions went from 316 tCO₂e to 161 tCO₂e over the same span (down 49%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 falls in band A — high performer (85–100). 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. Amazon Block 18's 36.2 kBtu/ft² across 556,007 sq ft works out to about 20.1 billion Btu (5,899 MWh-equivalent) in 2025. Its source EUI of 93.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,511,508 kWh of electricity and 17,299 therms of natural gas for the year.
Which law requires Amazon Block 18 to report its energy use?
Amazon Block 18 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:50739:2025). 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.
