How has Willamette Oaks's energy performance changed over time?
BuildingCensus holds 2 Portland disclosures for Willamette Oaks, covering report years 2023–2024. Its ENERGY STAR score went from 92 in 2023 to 91 in 2024 (-1 points); its best year on file was 2023, at 92. Site EUI moved from 38.3 kBtu/ft² (2023) to 38.7 kBtu/ft² (2024), an 1% increase. Reported emissions went from 112 tCO₂e to 122 tCO₂e over the same span (up 9%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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 Portland, 66% 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. Willamette Oaks's 38.7 kBtu/ft² across 39,459 sq ft works out to about 1.5 billion Btu (448 MWh-equivalent) in 2024. The disclosure also reports 296,684 kWh of electricity and 5,160 therms of natural gas for the year.
