How does NELSON APARTMENTS compare with other multifamily LR (1-4) buildings in Seattle?
The latest disclosures cover 53 multifamily LR (1-4) buildings in Seattle, out of 3,871 buildings citywide. NELSON APARTMENTS's ENERGY STAR score of 95 compares with an average of 73 across the 25 that report a score; it scores higher than 60% of them and lower than 36%. Its site EUI of 27.7 kBtu/ft² is about 31% below the average of 40.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.2 kgCO₂e/ft² is about 82% below the group average of 0.9 kgCO₂e/ft².
At 95,353 sq ft, it is about twice the average floor area of 45,933 sq ft for those buildings. It was built in 2007, 31 years later than the group's average year built (1976).
How has NELSON APARTMENTS's energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for NELSON APARTMENTS, covering report years 2015–2024. Its ENERGY STAR score went from 90 in 2018 to 95 in 2024 (+5 points); its best year on file was 2019, at 95. Site EUI moved from 29.7 kBtu/ft² (2015) to 27.7 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 11 tCO₂e to 10 tCO₂e over the same span (down 8%).
What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. NELSON APARTMENTS's 27.7 kBtu/ft² across 95,353 sq ft works out to about 2.6 billion Btu (774 MWh-equivalent) in 2024. Its source EUI of 77.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 494,023 kWh of electricity for the year.
Which law requires NELSON APARTMENTS to report its energy use?
NELSON 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 2024 disclosure (source record seattle:21203:2024). 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.
