What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). 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. OFFICE BUILDING, 4020 E MADISON ST's 38.1 kBtu/ft² across 28,848 sq ft works out to about 1.1 billion Btu (322 MWh-equivalent) in 2023. Its source EUI of 106.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 214,863 kWh of electricity for the year.
Which law requires OFFICE BUILDING, 4020 E MADISON ST to report its energy use?
OFFICE BUILDING, 4020 E MADISON ST 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.
