How has Urban Union (Amelia- Amazon Bldg)'s energy performance changed over time?

BuildingCensus holds 8 Seattle disclosures for Urban Union (Amelia- Amazon Bldg), covering report years 2018–2025. Its ENERGY STAR score went from 94 in 2018 to 90 in 2025 (-4 points); its best year on file was 2019, at 97. Site EUI moved from 50.3 kBtu/ft² (2018) to 44.7 kBtu/ft² (2025), a 11% decrease. Reported emissions went from 118 tCO₂e to 92 tCO₂e over the same span (down 22%).

What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 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. Urban Union (Amelia- Amazon Bldg)'s 44.7 kBtu/ft² across 422,272 sq ft works out to about 18.9 billion Btu (5,532 MWh-equivalent) in 2025. Its source EUI of 123.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,726,275 kWh of electricity and 3,392 therms of natural gas for the year.

Which law requires Urban Union (Amelia- Amazon Bldg) to report its energy use?
