Its emissions intensity of 0.8 kgCO₂e/ft² is about 68% below the group average of 2.5 kgCO₂e/ft².
At 188,339 sq ft, it is about half of the average floor area of 368,027 sq ft for those buildings. It was built in 1988, 12 years earlier than the group's average year built (2000). Across all 24 jurisdictions BuildingCensus covers, the 1,071 parking buildings average an ENERGY STAR score of 67 and a site EUI of 40.3 kBtu/ft².
How has First Hill Medical Building's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for First Hill Medical Building, covering report years 2015–2025. Its ENERGY STAR score went from 17 in 2015 to 31 in 2020 (+14 points). Site EUI moved from 105.4 kBtu/ft² (2015) to 73.6 kBtu/ft² (2025), a 30% decrease. Reported emissions went from 83 tCO₂e to 71 tCO₂e over the same span (down 14%).
What does a site EUI of 73.6 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. First Hill Medical Building's 73.6 kBtu/ft² across 188,339 sq ft works out to about 13.9 billion Btu (4,062 MWh-equivalent) in 2025. Its source EUI of 192.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,715,445 kWh of electricity and 7,064 therms of natural gas for the year.
Which law requires First Hill Medical Building to report its energy use?
First Hill Medical Building 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:776:2025). 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.
