Compliance context

Seattle Energy Benchmarking Ordinance (SMC 22.920)

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.

How does 98 Norfolk compare with other non-refrigerated warehouse buildings in Seattle?

The latest disclosures cover 164 non-refrigerated warehouse buildings in Seattle, out of 3,871 buildings citywide. 98 Norfolk's ENERGY STAR score of 84 compares with an average of 58 across the 117 that report a score; it scores higher than 83% of them and lower than 15%. Its site EUI of 18.0 kBtu/ft² is about 41% below the average of 30.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.5 kgCO₂e/ft² is about half of the group average of 0.9 kgCO₂e/ft².

At 60,448 sq ft, it is roughly in line with the average floor area of 58,727 sq ft for those buildings. It was built in 1978, 18 years later than the group's average year built (1960). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².

How has 98 Norfolk's energy performance changed over time?

BuildingCensus holds 11 Seattle disclosures for 98 Norfolk, covering report years 2015–2025. Its ENERGY STAR score went from 93 in 2015 to 84 in 2025 (-9 points); its best year on file was 2015, at 93. Site EUI moved from 14.7 kBtu/ft² (2015) to 18.0 kBtu/ft² (2025), an 22% increase. Reported emissions went from 21 tCO₂e to 28 tCO₂e over the same span (up 36%).

What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. 98 Norfolk's 18.0 kBtu/ft² across 60,448 sq ft works out to about 1.1 billion Btu (319 MWh-equivalent) in 2025. Its source EUI of 36.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 181,558 kWh of electricity and 4,658 therms of natural gas for the year.

Which law requires 98 Norfolk to report its energy use?

98 Norfolk 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:822:2025). 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.
