Nikkei Manor

How does Nikkei Manor compare with other senior living community buildings in Seattle?

The latest disclosures cover 48 senior living community buildings in Seattle, out of 3,871 buildings citywide. Nikkei Manor's ENERGY STAR score of 72 compares with an average of 72 across the 40 that report a score; it scores higher than 35% of them and lower than 60%. Its site EUI of 63.2 kBtu/ft² is roughly in line with the average of 66.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.8 kgCO₂e/ft² is roughly in line with the group average of 1.7 kgCO₂e/ft².

At 43,380 sq ft, it is about 68% below the average floor area of 136,458 sq ft for those buildings. It was built in 1998, 7 years later than the group's average year built (1991). Across all 24 jurisdictions BuildingCensus covers, the 1,181 senior living community buildings average an ENERGY STAR score of 71 and a site EUI of 73.6 kBtu/ft².

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

BuildingCensus holds 11 Seattle disclosures for Nikkei Manor, covering report years 2015–2025. Its ENERGY STAR score went from 53 in 2015 to 72 in 2025 (+19 points); its best year on file was 2024, at 72. Site EUI moved from 70.4 kBtu/ft² (2015) to 63.2 kBtu/ft² (2025), a 10% decrease. Reported emissions went from 84 tCO₂e to 77 tCO₂e over the same span (down 9%).

What does an ENERGY STAR score of 72 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 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 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. Nikkei Manor's 63.2 kBtu/ft² across 43,380 sq ft works out to about 2.7 billion Btu (803 MWh-equivalent) in 2025. Its source EUI of 124.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 423,340 kWh of electricity and 12,967 therms of natural gas for the year.

Which law requires Nikkei Manor to report its energy use?

Nikkei 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:26730:2025). 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.
