How does 4545 Roosevelt Way Ne compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. 4545 Roosevelt Way Ne's ENERGY STAR score of 88 compares with an average of 76 across the 378 that report a score; it scores higher than 63% of them and lower than 33%. Its site EUI of 34.3 kBtu/ft² is about 23% 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 71% below the group average of 0.7 kgCO₂e/ft².
At 91,100 sq ft, it is about half of the average floor area of 196,452 sq ft for those buildings. It was built in 1999, 34 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 4545 Roosevelt Way Ne's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 4545 Roosevelt Way Ne, covering report years 2015–2025. Its ENERGY STAR score went from 11 in 2015 to 88 in 2025 (+77 points). Site EUI moved from 165.1 kBtu/ft² (2015) to 34.3 kBtu/ft² (2025), a 79% decrease. Reported emissions went from 31 tCO₂e to 10 tCO₂e over the same span (down 69%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 4545 Roosevelt Way Ne's 34.3 kBtu/ft² across 91,100 sq ft works out to about 3.1 billion Btu (916 MWh-equivalent) in 2025. Its source EUI of 96.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 483,007 kWh of electricity for the year.
Which law requires 4545 Roosevelt Way Ne to report its energy use?
4545 Roosevelt Way Ne 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:26997:2025). 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.
