Metropolitan Park Apartments's ENERGY STAR score of 96 compares with an average of 83 across the 1,652 that report a score; it scores higher than 65% of them and lower than 30%. Its site EUI of 24.0 kBtu/ft² is about 31% below the average of 34.9 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 64% below the group average of 0.7 kgCO₂e/ft².

At 97,737 sq ft, it is about 13% above the average floor area of 86,468 sq ft for those buildings. It was built in 1991, 8 years later than the group's average year built (1983).

How has Metropolitan Park Apartments's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Metropolitan Park Apartments, covering report years 2015–2025. Its ENERGY STAR score went from 87 in 2015 to 96 in 2025 (+9 points); its best year on file was 2020, at 99. Site EUI moved from 27.8 kBtu/ft² (2015) to 24.0 kBtu/ft² (2025), a 14% decrease. Reported emissions went from 47 tCO₂e to 24 tCO₂e over the same span (down 49%).

What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Metropolitan Park Apartments's 24.0 kBtu/ft² across 97,737 sq ft works out to about 2.3 billion Btu (687 MWh-equivalent) in 2025. Its source EUI of 63.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 620,191 kWh of electricity and 2,278 therms of natural gas for the year.

Which law requires Metropolitan Park Apartments to report its energy use?

Metropolitan Park 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:26843:2025). 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.
