How has COMMUTER CENTER BUILDING's energy performance changed over time?
BuildingCensus holds 3 Seattle disclosures for COMMUTER CENTER BUILDING, covering report years 2015–2017. Site EUI moved from 53.2 kBtu/ft² (2015) to 64.0 kBtu/ft² (2017), an 20% increase. Reported emissions went from 15 tCO₂e to 19 tCO₂e over the same span (up 20%).
What does a site EUI of 64.0 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. COMMUTER CENTER BUILDING's 64.0 kBtu/ft² across 32,160 sq ft works out to about 2.1 billion Btu (603 MWh-equivalent) in 2017. Its source EUI of 200.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 936,101 kWh of electricity for the year.
Which law requires COMMUTER CENTER BUILDING to report its energy use?
COMMUTER CENTER BUILDING 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 2017 disclosure (source record seattle:23861:2017). 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.
