How does OVERLOOK AT MAGNOLIA (BLDG C) compare with other multifamily MR (5-9) buildings in Seattle?
The latest disclosures cover 22 multifamily MR (5-9) buildings in Seattle, out of 3,871 buildings citywide. OVERLOOK AT MAGNOLIA (BLDG C)'s ENERGY STAR score of 88 compares with an average of 91 across the 7 that report a score; it scores higher than 14% of them and lower than 71%. Its site EUI of 20.8 kBtu/ft² is about half of the average of 38.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 87% below the group average of 0.9 kgCO₂e/ft².
At 39,900 sq ft, it is about 67% below the average floor area of 121,840 sq ft for those buildings. It was built in 1970, 30 years earlier than the group's average year built (2000).
How has OVERLOOK AT MAGNOLIA (BLDG C)'s energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for OVERLOOK AT MAGNOLIA (BLDG C), covering report years 2015–2024. Its ENERGY STAR score went from 90 in 2015 to 88 in 2024 (-2 points); its best year on file was 2015, at 90. Site EUI moved from 22.0 kBtu/ft² (2015) to 20.8 kBtu/ft² (2024), a 5% decrease. Reported emissions went from 5 tCO₂e to 5 tCO₂e over the same span (down 6%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. OVERLOOK AT MAGNOLIA (BLDG C)'s 20.8 kBtu/ft² across 39,900 sq ft works out to about 0.8 billion Btu (243 MWh-equivalent) in 2024. Its source EUI of 58.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 242,688 kWh of electricity for the year.
Which law requires OVERLOOK AT MAGNOLIA (BLDG C) to report its energy use?
OVERLOOK AT MAGNOLIA (BLDG C) 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 2024 disclosure (source record seattle:27688:2024). 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.
