How has Dunn Motors Building's energy performance changed over time?
BuildingCensus holds 9 Seattle disclosures for Dunn Motors Building, covering report years 2017–2025. Its ENERGY STAR score was 100 in both 2017 and 2025. Site EUI moved from 26.9 kBtu/ft² (2017) to 28.0 kBtu/ft² (2025), an 4% increase. Reported emissions went from 42 tCO₂e to 52 tCO₂e over the same span (up 24%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Dunn Motors Building's 28.0 kBtu/ft² across 117,555 sq ft works out to about 3.3 billion Btu (965 MWh-equivalent) in 2025. Its source EUI of 62.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 498,364 kWh of electricity and 8,347 therms of natural gas for the year.
Which law requires Dunn Motors Building to report its energy use?
Dunn Motors Building 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:26118:2025). 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.
