How has Ori Stone Way Apartments's energy performance changed over time?
BuildingCensus holds 3 Seattle disclosures for Ori Stone Way Apartments, covering report years 2023–2025. Its ENERGY STAR score went from 89 in 2023 to 97 in 2025 (+8 points). Site EUI moved from 24.0 kBtu/ft² (2023) to 21.7 kBtu/ft² (2025), a 10% decrease. Reported emissions went from 3 tCO₂e to 4 tCO₂e over the same span (up 16%).
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. Ori Stone Way Apartments's 21.7 kBtu/ft² across 36,411 sq ft works out to about 0.8 billion Btu (232 MWh-equivalent) in 2025. Its source EUI of 60.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 186,992 kWh of electricity for the year.
