Its site EUI of 45.8 kBtu/ft² is about 31% 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 1.0 kgCO₂e/ft² is about 42% below the group average of 1.7 kgCO₂e/ft².

At 353,300 sq ft, it is about 159% above the average floor area of 136,458 sq ft for those buildings. It was built in 2018, 27 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 Murano Senior Living's energy performance changed over time?

BuildingCensus holds 6 Seattle disclosures for Murano Senior Living, covering report years 2020–2025. Its ENERGY STAR score went from 46 in 2022 to 98 in 2025 (+52 points); its best year on file was 2024, at 99. Site EUI moved from 40.6 kBtu/ft² (2022) to 45.8 kBtu/ft² (2025), an 13% increase. Reported emissions went from 54 tCO₂e to 305 tCO₂e over the same span (up 463%).

What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Murano Senior Living's 45.8 kBtu/ft² across 353,300 sq ft works out to about 16.2 billion Btu (4,742 MWh-equivalent) in 2025. Its source EUI of 100.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,710,728 kWh of electricity and 48,013 therms of natural gas for the year.

Which law requires Murano Senior Living to report its energy use?

Murano Senior 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:50661:2025). 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.
