How does Fraser Boiler Service compare with other other buildings in Seattle?
The latest disclosures cover 45 other buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 288.6 kBtu/ft² is about 386% above the average of 59.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.2 kgCO₂e/ft² is about twice the group average of 1.1 kgCO₂e/ft².
At 28,109 sq ft, it is about half of the average floor area of 55,708 sq ft for those buildings. It was built in 1966, 14 years later than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 1,327 other buildings average an ENERGY STAR score of 60 and a site EUI of 63.3 kBtu/ft².
How has Fraser Boiler Service's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Fraser Boiler Service, covering report years 2015–2025. Site EUI moved from 81.8 kBtu/ft² (2015) to 288.6 kBtu/ft² (2025), an 253% increase. Reported emissions went from 26 tCO₂e to 62 tCO₂e over the same span (up 142%).
What does a site EUI of 288.6 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. Fraser Boiler Service's 288.6 kBtu/ft² across 28,109 sq ft works out to about 8.1 billion Btu (2,377 MWh-equivalent) in 2025. Its source EUI of 787.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,280,853 kWh of electricity and 3,309 therms of natural gas for the year.
Which law requires Fraser Boiler Service to report its energy use?
Fraser Boiler Service 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:23397:2025). 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.
