Its site EUI of 36.9 kBtu/ft² is about 18% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.6 kgCO₂e/ft² is about 10% below the group average of 0.7 kgCO₂e/ft².

At 536,697 sq ft, it is about 173% above the average floor area of 196,452 sq ft for those buildings. It was built in 2014, 49 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has 400 Fairview Office Bldg's energy performance changed over time?

BuildingCensus holds 10 Seattle disclosures for 400 Fairview Office Bldg, covering report years 2016–2025. Its ENERGY STAR score went from 98 in 2016 to 92 in 2025 (-6 points); its best year on file was 2016, at 98. Site EUI moved from 37.9 kBtu/ft² (2016) to 36.9 kBtu/ft² (2025), a 3% decrease. Reported emissions went from 233 tCO₂e to 239 tCO₂e over the same span (up 2%).

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. 400 Fairview Office Bldg's 36.9 kBtu/ft² across 536,697 sq ft works out to about 19.8 billion Btu (5,804 MWh-equivalent) in 2025. Its source EUI of 87.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,107,826 kWh of electricity and 34,003 therms of natural gas for the year.

Which law requires 400 Fairview Office Bldg to report its energy use?

400 Fairview Office 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:50054:2025). 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.
