Maple Leaf Assisted Living

How does Maple Leaf Assisted Living 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. Maple Leaf Assisted Living's ENERGY STAR score of 64 compares with an average of 72 across the 40 that report a score; it scores higher than 28% of them and lower than 68%. Its site EUI of 38.6 kBtu/ft² is about 42% 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 0.8 kgCO₂e/ft² is about half of the group average of 1.7 kgCO₂e/ft².

At 99,941 sq ft, it is about 27% below the average floor area of 136,458 sq ft for those buildings. It was built in 2005, 14 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 Maple Leaf Assisted Living's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for Maple Leaf Assisted Living, covering report years 2015–2025. Its ENERGY STAR score went from 73 in 2015 to 64 in 2025 (-9 points); its best year on file was 2019, at 95. Site EUI moved from 47.4 kBtu/ft² (2015) to 38.6 kBtu/ft² (2025), a 19% decrease. Reported emissions went from 78 tCO₂e to 95 tCO₂e over the same span (up 22%).

What does an ENERGY STAR score of 64 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 64 means the building performs better than about 64% of its national peers. BuildingCensus bands the score into report-card grades; 64 falls in band C — below median (55–69). It sits 11 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. Maple Leaf Assisted Living's 38.6 kBtu/ft² across 99,941 sq ft works out to about 3.9 billion Btu (1,131 MWh-equivalent) in 2025. Its source EUI of 84.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 833,974 kWh of electricity and 14,947 therms of natural gas for the year.

Which law requires Maple Leaf Assisted Living to report its energy use?

Maple Leaf Assisted Living 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:26249:2025). 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.
