How does 2200 1st Ave S compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. 2200 1st Ave S's ENERGY STAR score of 87 compares with an average of 76 across the 378 that report a score; it scores higher than 60% of them and lower than 37%. Its site EUI of 38.8 kBtu/ft² is about 13% 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 0.2 kgCO₂e/ft² is about 69% below the group average of 0.7 kgCO₂e/ft².
At 129,000 sq ft, it is about 34% below the average floor area of 196,452 sq ft for those buildings. It was built in 1900, 65 years earlier 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 2200 1st Ave S's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 2200 1st Ave S, covering report years 2015–2025. Its ENERGY STAR score went from 85 in 2015 to 87 in 2025 (+2 points); its best year on file was 2020, at 93. Site EUI moved from 38.0 kBtu/ft² (2015) to 38.8 kBtu/ft² (2025), an 2% increase. Reported emissions went from 23 tCO₂e to 24 tCO₂e over the same span (up 4%).
What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. 2200 1st Ave S's 38.8 kBtu/ft² across 129,000 sq ft works out to about 5 billion Btu (1,467 MWh-equivalent) in 2025. Its source EUI of 108.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,210,202 kWh of electricity for the year.
Which law requires 2200 1st Ave S to report its energy use?
2200 1st Ave S 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:625:2025). 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.
