Market Place One & Two

How does Market Place One & Two compare with other mixed use property buildings in Seattle?

The latest disclosures cover 157 mixed use property buildings in Seattle, out of 3,871 buildings citywide. Market Place One & Two's ENERGY STAR score of 91 compares with an average of 74 across the 29 that report a score; it scores higher than 59% of them and lower than 31%. Its site EUI of 44.3 kBtu/ft² is about 36% below the average of 68.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.0 kgCO₂e/ft² is about 29% below the group average of 1.4 kgCO₂e/ft².

At 281,435 sq ft, it is about 70% above the average floor area of 165,352 sq ft for those buildings. It was built in 1979, 11 years later than the group's average year built (1968). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².

How has Market Place One & Two's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Market Place One & Two, covering report years 2015–2025. Its ENERGY STAR score went from 94 in 2015 to 91 in 2025 (-3 points); its best year on file was 2016, at 95. Site EUI moved from 40.3 kBtu/ft² (2015) to 44.3 kBtu/ft² (2025), an 10% increase. Reported emissions went from 63 tCO₂e to 149 tCO₂e over the same span (up 135%).

What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. Market Place One & Two's 44.3 kBtu/ft² across 281,435 sq ft works out to about 12.5 billion Btu (3,654 MWh-equivalent) in 2025. Its source EUI of 96.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,239,922 kWh of electricity and 23,485 therms of natural gas for the year.

Which law requires Market Place One & Two to report its energy use?

Market Place One & Two 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:757:2025). 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.
