The latest disclosures cover 86 hotel buildings in Seattle, out of 3,871 buildings citywide. Virginia Mason- Baroness Hotel's ENERGY STAR score of 97 compares with an average of 76 across the 78 that report a score; it scores higher than 81% of them and lower than 14%. Its site EUI of 33.9 kBtu/ft² is about half of the average of 68.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.0 kgCO₂e/ft² is about half of the group average of 2.0 kgCO₂e/ft².

At 35,770 sq ft, it is about 78% below the average floor area of 165,912 sq ft for those buildings. It was built in 1928, 42 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 Virginia Mason- Baroness Hotel's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Virginia Mason- Baroness Hotel, covering report years 2015–2025. Its ENERGY STAR score went from 59 in 2015 to 97 in 2025 (+38 points). Site EUI moved from 72.7 kBtu/ft² (2015) to 33.9 kBtu/ft² (2025), a 53% decrease. Reported emissions went from 111 tCO₂e to 37 tCO₂e over the same span (down 67%).

What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. Virginia Mason- Baroness Hotel's 33.9 kBtu/ft² across 35,770 sq ft works out to about 1.2 billion Btu (355 MWh-equivalent) in 2025. Its source EUI of 64.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 172,122 kWh of electricity and 6,267 therms of natural gas for the year.

Which law requires Virginia Mason- Baroness Hotel to report its energy use?

Virginia Mason- Baroness 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:23408:2025). 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.
