Plaza Roberto Maestas (East Bldg)'s ENERGY STAR score of 100 compares with an average of 83 across the 1,652 that report a score; it scores higher than 88% of them. Its site EUI of 12.1 kBtu/ft² is about 65% below the average of 34.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 64,873 sq ft, it is about 25% below the average floor area of 86,468 sq ft for those buildings. It was built in 2016, 33 years later than the group's average year built (1983).

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. Plaza Roberto Maestas (East Bldg)'s 12.1 kBtu/ft² across 64,873 sq ft works out to about 0.8 billion Btu (230 MWh-equivalent) in 2025. Its source EUI of 12.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,077 therms of natural gas for the year.
Which law requires Plaza Roberto Maestas (East Bldg) to report its energy use?
Plaza Roberto Maestas (East Bldg) 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. The record shown here is the report-year 2025 disclosure (source record seattle:52102:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
