Its ENERGY STAR score went from 39 in 2023 to 35 in 2025 (-4 points); its best year on file was 2024, at 40. Site EUI moved from 44.9 kBtu/ft² (2023) to 46.6 kBtu/ft² (2025), an 4% increase. Reported emissions went from 131 tCO₂e to 139 tCO₂e over the same span (up 6%).
What does an ENERGY STAR score of 35 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 35 means the building performs better than about 35% of its national peers. BuildingCensus bands the score into report-card grades; 35 falls in band D — lowest band (1–54). It sits 40 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. Skyline Olympic Tower's 46.6 kBtu/ft² across 188,183 sq ft works out to about 8.8 billion Btu (2,570 MWh-equivalent) in 2025. Its source EUI of 102.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,254,223 kWh of electricity and 22,010 therms of natural gas for the year.
Which law requires Skyline Olympic Tower to report its energy use?
