Its site EUI of 305.1 kBtu/ft² is about 346% above the average of 68.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 10.6 kgCO₂e/ft² is about 431% above the group average of 2.0 kgCO₂e/ft².
At 76,631 sq ft, it is about half of the average floor area of 165,912 sq ft for those buildings. It was built in 1908, 62 years earlier than the group's average year built (1971). Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².
How has Sorrento Hotel's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Sorrento Hotel, covering report years 2015–2025. Its ENERGY STAR score went from 24 in 2015 to 1 in 2025 (-23 points); its best year on file was 2020, at 98. Site EUI moved from 94.4 kBtu/ft² (2015) to 305.1 kBtu/ft² (2025), an 223% increase. Reported emissions went from 252 tCO₂e to 212 tCO₂e over the same span (down 16%).
What does an ENERGY STAR score of 1 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: 1 is the bottom of the scale. BuildingCensus bands the score into report-card grades; 1 falls in band D — lowest band (1–54). It sits 74 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. Sorrento Hotel's 305.1 kBtu/ft² across 76,631 sq ft works out to about 23.4 billion Btu (6,852 MWh-equivalent) in 2025. Its source EUI of 526.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 688,719 kWh of electricity and 37,520 therms of natural gas for the year.
Which law requires Sorrento Hotel to report its energy use?
Sorrento Hotel 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:95:2025). 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.
