Compliance context
Seattle Energy Benchmarking Ordinance (SMC 22.920)
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.

How does Georgetown Squared compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Georgetown Squared's ENERGY STAR score of 74 compares with an average of 76 across the 378 that report a score; it scores higher than 32% of them and lower than 67%. Its site EUI of 45.1 kBtu/ft² is roughly in line with the average of 44.8 kBtu/ft². Its emissions intensity of 0.3 kgCO₂e/ft² is about 63% below the group average of 0.7 kgCO₂e/ft².
At 390,295 sq ft, it is about twice the average floor area of 196,452 sq ft for those buildings. It was built in 1982, 17 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 Georgetown Squared's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Georgetown Squared, covering report years 2015–2025. Its ENERGY STAR score went from 95 in 2015 to 74 in 2025 (-21 points); its best year on file was 2015, at 95. Site EUI moved from 32.3 kBtu/ft² (2015) to 45.1 kBtu/ft² (2025), an 40% increase. Reported emissions went from 46 tCO₂e to 72 tCO₂e over the same span (up 59%).
What does an ENERGY STAR score of 74 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 74 means the building performs better than about 74% of its national peers. BuildingCensus bands the score into report-card grades; 74 falls in band B — above median (70–84). It sits 1 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. Georgetown Squared's 45.1 kBtu/ft² across 390,295 sq ft works out to about 17.6 billion Btu (5,159 MWh-equivalent) in 2025. Its source EUI of 126.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,662,982 kWh of electricity for the year.
Which law requires Georgetown Squared to report its energy use?
Georgetown Squared 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:526:2025). 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.
