How has The Marquis Coop Apartments's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for The Marquis Coop Apartments, covering report years 2015–2025. Its ENERGY STAR score went from 98 in 2015 to 97 in 2025 (-1 points); its best year on file was 2021, at 100. Site EUI moved from 32.7 kBtu/ft² (2015) to 36.4 kBtu/ft² (2025), an 11% increase. Reported emissions went from 57 tCO₂e to 62 tCO₂e over the same span (up 8%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. The Marquis Coop Apartments's 36.4 kBtu/ft² across 40,112 sq ft works out to about 1.5 billion Btu (428 MWh-equivalent) in 2025. Its source EUI of 49.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 74,094 kWh of electricity and 12,085 therms of natural gas for the year.
Which law requires The Marquis Coop Apartments to report its energy use?
The Marquis Coop Apartments 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:27836:2025).
