How has Colina East + West Combined's energy performance changed over time?
BuildingCensus holds 4 Seattle disclosures for Colina East + West Combined, covering report years 2022–2025. Its ENERGY STAR score went from 99 in 2022 to 97 in 2025 (-2 points); its best year on file was 2022, at 99. Site EUI moved from 24.4 kBtu/ft² (2022) to 27.1 kBtu/ft² (2025), an 11% increase. Reported emissions went from 16 tCO₂e to 17 tCO₂e over the same span (up 12%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. Colina East + West Combined's 27.1 kBtu/ft² across 120,674 sq ft works out to about 3.3 billion Btu (958 MWh-equivalent) in 2025. Its source EUI of 75.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 861,815 kWh of electricity and 71 therms of natural gas for the year.
