Its site EUI of 19.6 kBtu/ft² is about 71% below the average of 68.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 92% below the group average of 1.4 kgCO₂e/ft².
At 78,920 sq ft, it is about half of the average floor area of 165,352 sq ft for those buildings. It was built in 1929, 39 years earlier than the group's average year built (1968). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².
How has Old Navy's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Old Navy, covering report years 2015–2025. Its ENERGY STAR score went from 67 in 2015 to 85 in 2018 (+18 points). Site EUI moved from 133.2 kBtu/ft² (2015) to 19.6 kBtu/ft² (2025), a 85% decrease. Reported emissions went from 133 tCO₂e to 9 tCO₂e over the same span (down 93%).
What does a site EUI of 19.6 kBtu/ft² mean?
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. Old Navy's 19.6 kBtu/ft² across 78,920 sq ft works out to about 1.5 billion Btu (453 MWh-equivalent) in 2025. Its source EUI of 54.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 453,358 kWh of electricity for the year.
Which law requires Old Navy to report its energy use?
Old Navy 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:756:2025). 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.
