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 4300 Roosevelt compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. 4300 Roosevelt's ENERGY STAR score of 98 compares with an average of 76 across the 378 that report a score; it scores higher than 93% of them and lower than 5%. Its site EUI of 20.9 kBtu/ft² is about half of 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 0.1 kgCO₂e/ft² is about 83% below the group average of 0.7 kgCO₂e/ft².
At 220,649 sq ft, it is about 12% above the average floor area of 196,452 sq ft for those buildings. It was built in 2002, 37 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 4300 Roosevelt's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 4300 Roosevelt, covering report years 2015–2025. Its ENERGY STAR score went from 93 in 2015 to 98 in 2025 (+5 points). Site EUI moved from 43.2 kBtu/ft² (2015) to 20.9 kBtu/ft² (2025), a 52% decrease. Reported emissions went from 37 tCO₂e to 18 tCO₂e over the same span (down 52%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 4300 Roosevelt's 20.9 kBtu/ft² across 220,649 sq ft works out to about 4.6 billion Btu (1,352 MWh-equivalent) in 2025. Its source EUI of 58.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 893,785 kWh of electricity for the year.
Which law requires 4300 Roosevelt to report its energy use?
4300 Roosevelt 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:368:2025). 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.
