The latest disclosures cover 1,971 multifamily housing buildings in Seattle, out of 3,871 buildings citywide. Orenda (rn185)'s ENERGY STAR score of 96 compares with an average of 83 across the 1,652 that report a score; it scores higher than 65% of them and lower than 30%. Its site EUI of 32.0 kBtu/ft² is roughly in line with the average of 34.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 193,783 sq ft, it is about 124% above the average floor area of 86,468 sq ft for those buildings. It was built in 2021, 38 years later than the group's average year built (1983). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has Orenda (rn185)'s energy performance changed over time?
BuildingCensus holds 4 Seattle disclosures for Orenda (rn185), covering report years 2022–2025. Its ENERGY STAR score went from 98 in 2022 to 96 in 2025 (-2 points); its best year on file was 2022, at 98. Site EUI moved from 30.4 kBtu/ft² (2022) to 32.0 kBtu/ft² (2025), an 5% increase. Reported emissions went from 103 tCO₂e to 112 tCO₂e over the same span (up 8%).
What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Orenda (rn185)'s 32.0 kBtu/ft² across 193,783 sq ft works out to about 6.2 billion Btu (1,817 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 1,364,505 kWh of electricity and 15,507 therms of natural gas for the year.
Which law requires Orenda (rn185) to report its energy use?
