What does an ENERGY STAR score of 36 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 36 means the building performs better than about 36% of its national peers. BuildingCensus bands the score into report-card grades; 36 falls in band D — lowest band (1–54). It sits 39 points below 75, the threshold for ENERGY STAR certification. 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. MARION 823- DEMOLISHED- INACTIVE's 78.1 kBtu/ft² across 38,539 sq ft works out to about 3 billion Btu (882 MWh-equivalent) in 2019. Its source EUI of 218.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 599,066 kWh of electricity for the year.
Which law requires MARION 823- DEMOLISHED- INACTIVE to report its energy use?
MARION 823- DEMOLISHED- INACTIVE reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results.
