How has 410 Associates Office Bldg's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for 410 Associates Office Bldg, covering report years 2015–2025. Its ENERGY STAR score went from 19 in 2015 to 20 in 2025 (+1 points). Site EUI moved from 98.7 kBtu/ft² (2015) to 90.7 kBtu/ft² (2025), a 8% decrease. Reported emissions went from 46 tCO₂e to 53 tCO₂e over the same span (up 16%).
What does an ENERGY STAR score of 20 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 20 means the building performs better than about 20% of its national peers. BuildingCensus bands the score into report-card grades; 20 falls in band D — lowest band (1–54). It sits 55 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. 410 Associates Office Bldg's 90.7 kBtu/ft² across 20,410 sq ft works out to about 1.9 billion Btu (543 MWh-equivalent) in 2025. Its source EUI of 171.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 259,679 kWh of electricity and 9,649 therms of natural gas for the year.
Which law requires 410 Associates Office Bldg to report its energy use?
410 Associates Office Bldg 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:27567:2025). 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.
