How has West Newton Flats's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for West Newton Flats, covering report years 2015–2025. Its ENERGY STAR score went from 41 in 2015 to 33 in 2016 (-8 points); its best year on file was 2015, at 41. Site EUI moved from 37.3 kBtu/ft² (2015) to 32.9 kBtu/ft² (2025), a 12% decrease. Reported emissions went from 12 tCO₂e to 8 tCO₂e over the same span (down 33%).
What does a site EUI of 32.9 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. West Newton Flats's 32.9 kBtu/ft² across 32,395 sq ft works out to about 1.1 billion Btu (312 MWh-equivalent) in 2025. Its source EUI of 82.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 157,290 kWh of electricity and 1,053 therms of natural gas for the year.
Which law requires West Newton Flats to report its energy use?
West Newton Flats 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:49721:2025). 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.
