How does Springbrook Bldg compare with other medical office buildings in Seattle?

The latest disclosures cover 45 medical office buildings in Seattle, out of 3,871 buildings citywide. Springbrook Bldg's ENERGY STAR score of 37 compares with an average of 60 across the 32 that report a score; it scores higher than 25% of them and lower than 72%. Its site EUI of 61.1 kBtu/ft² is about 31% below the average of 88.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.4 kgCO₂e/ft² is about 76% below the group average of 1.5 kgCO₂e/ft².

At 45,264 sq ft, it is about 69% below the average floor area of 145,612 sq ft for those buildings. It was built in 1984, 5 years later than the group's average year built (1979). Across all 24 jurisdictions BuildingCensus covers, the 1,266 medical office buildings average an ENERGY STAR score of 64 and a site EUI of 92.2 kBtu/ft².

How has Springbrook Bldg's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Springbrook Bldg, covering report years 2015–2025. Its ENERGY STAR score went from 8 in 2015 to 37 in 2025 (+29 points); its best year on file was 2023, at 37. Site EUI moved from 78.0 kBtu/ft² (2015) to 61.1 kBtu/ft² (2025), a 22% decrease. Reported emissions went from 10 tCO₂e to 8 tCO₂e over the same span (down 20%).

What does an ENERGY STAR score of 37 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 37 means the building performs better than about 37% of its national peers. BuildingCensus bands the score into report-card grades; 37 falls in band D — lowest band (1–54). It sits 38 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. Springbrook Bldg's 61.1 kBtu/ft² across 45,264 sq ft works out to about 2.8 billion Btu (811 MWh-equivalent) in 2025. Its source EUI of 171.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 389,067 kWh of electricity for the year.

Which law requires Springbrook Bldg to report its energy use?

Springbrook Bldg 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:24252:2025). 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.
