Its site EUI of 25.9 kBtu/ft² is about 56% below the average of 59.4 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 roughly in line with the group average of 1.1 kgCO₂e/ft².
At 30,160 sq ft, it is about half of the average floor area of 55,708 sq ft for those buildings. It was built in 1969, 17 years later than the group's average year built (1952). Across all 24 jurisdictions BuildingCensus covers, the 1,327 other buildings average an ENERGY STAR score of 60 and a site EUI of 63.3 kBtu/ft².
How has Centurylink: Lake City Garage's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Centurylink: Lake City Garage, covering report years 2015–2025. Site EUI moved from 39.4 kBtu/ft² (2015) to 25.9 kBtu/ft² (2025), a 34% decrease. Reported emissions went from 48 tCO₂e to 31 tCO₂e over the same span (down 35%).
What does a site EUI of 25.9 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. Centurylink: Lake City Garage's 25.9 kBtu/ft² across 30,160 sq ft works out to about 0.8 billion Btu (229 MWh-equivalent) in 2025. Its source EUI of 37.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 51,196 kWh of electricity and 6,058 therms of natural gas for the year.
Which law requires Centurylink: Lake City Garage to report its energy use?
Centurylink: Lake City Garage 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:23343:2025). 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.
