Lowman And Hanford Building's ENERGY STAR score of 68 compares with an average of 76 across the 378 that report a score; it scores higher than 24% of them and lower than 74%. Its site EUI of 28.0 kBtu/ft² is about 38% 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 0.2 kgCO₂e/ft² is about 77% below the group average of 0.7 kgCO₂e/ft².
At 23,622 sq ft, it is about 88% below the average floor area of 196,452 sq ft for those buildings. It was built in 1900, 65 years earlier 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 Lowman And Hanford Building's energy performance changed over time?
BuildingCensus holds 6 Seattle disclosures for Lowman And Hanford Building, covering report years 2020–2025. Its ENERGY STAR score went from 80 in 2020 to 68 in 2025 (-12 points); its best year on file was 2024, at 93. Site EUI moved from 38.9 kBtu/ft² (2020) to 28.0 kBtu/ft² (2025), a 28% decrease. Reported emissions went from 6 tCO₂e to 6 tCO₂e over the same span (down 3%).
What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 points below 75, the threshold for ENERGY STAR certification. 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. Lowman And Hanford Building's 28.0 kBtu/ft² across 23,622 sq ft works out to about 0.7 billion Btu (194 MWh-equivalent) in 2025. Its source EUI of 78.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 283,949 kWh of electricity for the year.
Which law requires Lowman And Hanford Building to report its energy use?
Lowman And Hanford 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:19855:2025). 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.
