Seattle Children's Hospital Building Hope

How does Seattle Children's Hospital Building Hope compare with other hospital (general medical & surgical) buildings in Seattle?

The latest disclosures cover 11 hospital (general medical & surgical) buildings in Seattle, out of 3,871 buildings citywide. Seattle Children's Hospital Building Hope's ENERGY STAR score of 98 compares with an average of 76 across the 10 that report a score; it scores higher than 80% of them and lower than 10%. Its site EUI of 134.9 kBtu/ft² is about 26% below the average of 182.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.8 kgCO₂e/ft² is about 56% below the group average of 6.4 kgCO₂e/ft².

At 330,000 sq ft, it is about half of the average floor area of 676,225 sq ft for those buildings. It was built in 2013, 39 years later than the group's average year built (1974). Across all 24 jurisdictions BuildingCensus covers, the 748 hospital (general medical & surgical) buildings average an ENERGY STAR score of 59 and a site EUI of 238.7 kBtu/ft².

How has Seattle Children's Hospital Building Hope's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Seattle Children's Hospital Building Hope, covering report years 2015–2025. Its ENERGY STAR score went from 83 in 2015 to 98 in 2025 (+15 points). Site EUI moved from 201.8 kBtu/ft² (2015) to 134.9 kBtu/ft² (2025), a 33% decrease. Reported emissions went from 1,426 tCO₂e to 903 tCO₂e over the same span (down 37%).

What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Seattle Children's Hospital Building Hope's 134.9 kBtu/ft² across 330,000 sq ft works out to about 44.5 billion Btu (13,047 MWh-equivalent) in 2025. Its source EUI of 303.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,747,192 kWh of electricity and 137,260 therms of natural gas for the year.

Which law requires Seattle Children's Hospital Building Hope to report its energy use?

Seattle Children's Hospital Building Hope 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:49732:2025). 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.
