Emerald Landing I's ENERGY STAR score of 10 compares with an average of 76 across the 378 that report a score; it scores higher than 2% of them and lower than 98%. Its site EUI of 100.9 kBtu/ft² is about 125% above the average of 44.8 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.9 kgCO₂e/ft² is about 36% above the group average of 0.7 kgCO₂e/ft².
At 84,116 sq ft, it is about 57% below the average floor area of 196,452 sq ft for those buildings. It was built in 2012, 47 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 Emerald Landing I's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Emerald Landing I, covering report years 2015–2025. Its ENERGY STAR score went from 83 in 2015 to 10 in 2025 (-73 points); its best year on file was 2015, at 83. Site EUI moved from 38.3 kBtu/ft² (2015) to 100.9 kBtu/ft² (2025), an 163% increase. Reported emissions went from 14 tCO₂e to 55 tCO₂e over the same span (up 297%).
What does an ENERGY STAR score of 10 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 10 means the building performs better than about 10% of its national peers. BuildingCensus bands the score into report-card grades; 10 falls in band D — lowest band (1–54). It sits 65 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. Emerald Landing I's 100.9 kBtu/ft² across 84,116 sq ft works out to about 8.5 billion Btu (2,487 MWh-equivalent) in 2025. Its source EUI of 267.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,557,441 kWh of electricity and 4,983 therms of natural gas for the year.
Which law requires Emerald Landing I to report its energy use?
Emerald Landing I 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:20369:2025). 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.
