Compliance context
Seattle Energy Benchmarking Ordinance (SMC 22.920)
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.

How does Madison Center compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Madison Center's ENERGY STAR score of 93 compares with an average of 76 across the 378 that report a score; it scores higher than 79% of them and lower than 19%. Its site EUI of 31.1 kBtu/ft² is about 31% below the average of 44.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.3 kgCO₂e/ft² is about 59% below the group average of 0.7 kgCO₂e/ft².
At 990,000 sq ft, it is about 404% above the average floor area of 196,452 sq ft for those buildings. It was built in 2016, 51 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has Madison Center's energy performance changed over time?
BuildingCensus holds 8 Seattle disclosures for Madison Center, covering report years 2018–2025. Its ENERGY STAR score went from 100 in 2018 to 93 in 2025 (-7 points); its best year on file was 2018, at 100. Site EUI moved from 14.0 kBtu/ft² (2018) to 31.1 kBtu/ft² (2025), an 122% increase. Reported emissions went from 186 tCO₂e to 217 tCO₂e over the same span (up 16%).
What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Madison Center's 31.1 kBtu/ft² across 990,000 sq ft works out to about 30.8 billion Btu (9,023 MWh-equivalent) in 2025. Its source EUI of 83.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,394,486 kWh of electricity and 17,429 therms of natural gas for the year.
Which law requires Madison Center to report its energy use?
Madison Center 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:50096:2025). 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.
