How has Burke And Union Apartment's energy performance changed over time?
BuildingCensus holds 7 Seattle disclosures for Burke And Union Apartment, covering report years 2019–2025. Its ENERGY STAR score was 100 in both 2019 and 2025.

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Burke And Union Apartment's 30.7 kBtu/ft² across 84,996 sq ft works out to about 2.6 billion Btu (765 MWh-equivalent) in 2025. Its source EUI of 67.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 325,645 kWh of electricity and 5,867 therms of natural gas for the year.
