Norse Home

How does Norse Home 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. Norse Home's ENERGY STAR score of 100 compares with an average of 72 across the 40 that report a score; it scores higher than 90% of them. Its site EUI of 41.7 kBtu/ft² is about 37% below 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 1.4 kgCO₂e/ft² is about 17% below the group average of 1.7 kgCO₂e/ft².

At 83,008 sq ft, it is about 39% below the average floor area of 136,458 sq ft for those buildings. It was built in 1955, 36 years earlier 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 Norse Home's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Norse Home, covering report years 2015–2025. Its ENERGY STAR score went from 51 in 2015 to 100 in 2025 (+49 points). Site EUI moved from 81.7 kBtu/ft² (2015) to 41.7 kBtu/ft² (2025), a 49% decrease. Reported emissions went from 288 tCO₂e to 117 tCO₂e over the same span (down 59%).

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Norse Home's 41.7 kBtu/ft² across 83,008 sq ft works out to about 3.5 billion Btu (1,014 MWh-equivalent) in 2025. Its source EUI of 68.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 342,142 kWh of electricity and 22,956 therms of natural gas for the year.

Which law requires Norse Home to report its energy use?

Norse Home 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:26429:2025). 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.
