Its site EUI of 29.4 kBtu/ft² is about 67% 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 0.2 kgCO₂e/ft² is about 89% below the group average of 1.5 kgCO₂e/ft².

At 26,930 sq ft, it is about 82% below the average floor area of 145,612 sq ft for those buildings. Its 1980 construction date is close to 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 North Seattle Professional Cente's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for North Seattle Professional Cente, covering report years 2015–2025. Its ENERGY STAR score went from 62 in 2015 to 99 in 2025 (+37 points); its best year on file was 2023, at 99. Site EUI moved from 39.4 kBtu/ft² (2015) to 29.4 kBtu/ft² (2025), a 25% decrease. Reported emissions went from 6 tCO₂e to 5 tCO₂e over the same span (down 26%).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. North Seattle Professional Cente's 29.4 kBtu/ft² across 26,930 sq ft works out to about 0.8 billion Btu (232 MWh-equivalent) in 2025. Its source EUI of 82.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 231,660 kWh of electricity for the year.

Which law requires North Seattle Professional Cente to report its energy use?

North Seattle Professional Cente 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:21907:2025). 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.
