Meridian Manor

How does Meridian Manor compare with other multifamily housing buildings in Seattle?

The latest disclosures cover 1,971 multifamily housing buildings in Seattle, out of 3,871 buildings citywide. Meridian Manor's ENERGY STAR score of 42 compares with an average of 83 across the 1,652 that report a score; it scores higher than 6% of them and lower than 94%. Its site EUI of 46.4 kBtu/ft² is about 33% above the average of 34.9 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 0.3 kgCO₂e/ft² is about 61% below the group average of 0.7 kgCO₂e/ft².

At 75,070 sq ft, it is about 13% below the average floor area of 86,468 sq ft for those buildings. It was built in 1979, 4 years earlier than the group's average year built (1983). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has Meridian Manor's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Meridian Manor, covering report years 2015–2025. Its ENERGY STAR score went from 15 in 2015 to 42 in 2025 (+27 points). Site EUI moved from 52.1 kBtu/ft² (2015) to 46.4 kBtu/ft² (2025), a 11% decrease. Reported emissions went from 23 tCO₂e to 20 tCO₂e over the same span (down 11%).

What does an ENERGY STAR score of 42 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 42 means the building performs better than about 42% of its national peers. BuildingCensus bands the score into report-card grades; 42 falls in band D — lowest band (1–54). It sits 33 points below 75, the threshold for ENERGY STAR certification. 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. Meridian Manor's 46.4 kBtu/ft² across 75,070 sq ft works out to about 3.5 billion Btu (1,021 MWh-equivalent) in 2025. Its source EUI of 129.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,020,329 kWh of electricity for the year.

Which law requires Meridian Manor to report its energy use?

Meridian Manor 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:27584:2025). 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.
