How does Cedar Speedster compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Cedar Speedster's ENERGY STAR score of 67 compares with an average of 76 across the 378 that report a score; it scores higher than 23% of them and lower than 76%. Its site EUI of 41.7 kBtu/ft² is roughly in line with 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 66% below the group average of 0.7 kgCO₂e/ft².
At 47,322 sq ft, it is about 76% below the average floor area of 196,452 sq ft for those buildings. It was built in 2019, 54 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 Cedar Speedster's energy performance changed over time?
BuildingCensus holds 5 Seattle disclosures for Cedar Speedster, covering report years 2021–2025. Its ENERGY STAR score went from 62 in 2022 to 67 in 2025 (+5 points). Site EUI moved from 44.6 kBtu/ft² (2022) to 41.7 kBtu/ft² (2025), a 7% decrease. Reported emissions went from 7 tCO₂e to 7 tCO₂e over the same span (down 7%).
What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. 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. Cedar Speedster's 41.7 kBtu/ft² across 47,322 sq ft works out to about 2 billion Btu (578 MWh-equivalent) in 2025. Its source EUI of 116.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 348,587 kWh of electricity for the year.
Which law requires Cedar Speedster to report its energy use?
Cedar Speedster 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:50893:2025). 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.
