The latest disclosures cover 45 medical office buildings in Seattle, out of 3,871 buildings citywide. NORTHWEST KIDNEY CENTER's ENERGY STAR score of 79 compares with an average of 60 across the 32 that report a score; it scores higher than 66% of them and lower than 31%. Its site EUI of 62.8 kBtu/ft² is about 29% below the average of 88.3 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 roughly in line with the group average of 1.5 kgCO₂e/ft².
At 39,115 sq ft, it is about 73% below the average floor area of 145,612 sq ft for those buildings. It was built in 1963, 16 years earlier than the group's average year built (1979). Across all 24 jurisdictions BuildingCensus covers, the 1,266 medical office buildings average an ENERGY STAR score of 64 and a site EUI of 92.2 kBtu/ft².
How has NORTHWEST KIDNEY CENTER's energy performance changed over time?
BuildingCensus holds 10 Seattle disclosures for NORTHWEST KIDNEY CENTER, covering report years 2015–2024. Its ENERGY STAR score went from 71 in 2015 to 79 in 2024 (+8 points). Site EUI moved from 53.7 kBtu/ft² (2015) to 62.8 kBtu/ft² (2024), an 17% increase. Reported emissions went from 49 tCO₂e to 59 tCO₂e over the same span (up 21%).
What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 falls in band B — above median (70–84). 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. NORTHWEST KIDNEY CENTER's 62.8 kBtu/ft² across 39,115 sq ft works out to about 2.5 billion Btu (720 MWh-equivalent) in 2024. Its source EUI of 136.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 490,040 kWh of electricity and 9,308 therms of natural gas for the year.
Which law requires NORTHWEST KIDNEY CENTER to report its energy use?
NORTHWEST KIDNEY CENTER 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:21365:2024). 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.
