How has Courtyard By Marriott - Pioneer Sq's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Courtyard By Marriott - Pioneer Sq, covering report years 2015–2025. Its ENERGY STAR score went from 46 in 2015 to 75 in 2025 (+29 points); its best year on file was 2020, at 92. Site EUI moved from 77.0 kBtu/ft² (2015) to 72.7 kBtu/ft² (2025), a 6% decrease. Reported emissions went from 322 tCO₂e to 304 tCO₂e over the same span (down 6%).

What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 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. Courtyard By Marriott - Pioneer Sq's 72.7 kBtu/ft² across 163,984 sq ft works out to about 11.9 billion Btu (3,494 MWh-equivalent) in 2025. Its source EUI of 150.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,034,441 kWh of electricity and 49,825 therms of natural gas for the year.

Which law requires Courtyard By Marriott - Pioneer Sq to report its energy use?

Courtyard By Marriott - Pioneer Sq 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:12:2025). 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.
