The End Of Elliott Complex's ENERGY STAR score of 56 compares with an average of 76 across the 378 that report a score; it scores higher than 14% of them and lower than 85%. Its site EUI of 28.0 kBtu/ft² is about 38% 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 0.3 kgCO₂e/ft² is about 56% below the group average of 0.7 kgCO₂e/ft².
At 59,800 sq ft, it is about 70% below the average floor area of 196,452 sq ft for those buildings. It was built in 1937, 28 years earlier 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 The End Of Elliott Complex's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for The End Of Elliott Complex, covering report years 2015–2025. Its ENERGY STAR score went from 55 in 2015 to 56 in 2025 (+1 points); its best year on file was 2020, at 73. Site EUI moved from 53.9 kBtu/ft² (2015) to 28.0 kBtu/ft² (2025), a 48% decrease. Reported emissions went from 48 tCO₂e to 18 tCO₂e over the same span (down 61%).
What does an ENERGY STAR score of 56 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 56 means the building performs better than about 56% of its national peers. BuildingCensus bands the score into report-card grades; 56 falls in band C — below median (55–69). It sits 19 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. The End Of Elliott Complex's 28.0 kBtu/ft² across 59,800 sq ft works out to about 1.7 billion Btu (491 MWh-equivalent) in 2025. Its source EUI of 72.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 429,606 kWh of electricity and 2,075 therms of natural gas for the year.
Which law requires The End Of Elliott Complex to report its energy use?
The End Of Elliott Complex 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:702:2025). 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.
