How does UW Medicine Phase 3 compare with other laboratory buildings in Seattle?
The latest disclosures cover 32 laboratory buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 200.3 kBtu/ft² is about 12% above the average of 178.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.0 kgCO₂e/ft² is roughly in line with the group average of 4.6 kgCO₂e/ft².
At 339,591 sq ft, it is about 68% above the average floor area of 202,547 sq ft for those buildings. It was built in 2013, 27 years later than the group's average year built (1986). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has UW Medicine Phase 3's energy performance changed over time?
BuildingCensus holds 6 Seattle disclosures for UW Medicine Phase 3, covering report years 2019–2024. Site EUI moved from 191.8 kBtu/ft² (2019) to 200.3 kBtu/ft² (2024), an 4% increase. Reported emissions went from 1,726 tCO₂e to 1,689 tCO₂e over the same span (down 2%).
What does a site EUI of 200.3 kBtu/ft² mean?
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. UW Medicine Phase 3's 200.3 kBtu/ft² across 339,591 sq ft works out to about 68 billion Btu (19,935 MWh-equivalent) in 2024. Its source EUI of 418.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 11,771,860 kWh of electricity and 274,717 therms of natural gas for the year.
Which law requires UW Medicine Phase 3 to report its energy use?
UW Medicine Phase 3 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 2024 disclosure (source record seattle:49783:2024). 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.
