How has MERCER ARENA - SEATTLE CENTER's energy performance changed over time?
BuildingCensus holds 3 Seattle disclosures for MERCER ARENA - SEATTLE CENTER, covering report years 2015–2017. Site EUI moved from 8.6 kBtu/ft² (2015) to 2.6 kBtu/ft² (2017), a 70% decrease. Reported emissions went from 5 tCO₂e to 2 tCO₂e over the same span (down 70%).
What does a site EUI of 2.6 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. MERCER ARENA - SEATTLE CENTER's 2.6 kBtu/ft² across 60,696 sq ft works out to about 0.2 billion Btu (46 MWh-equivalent) in 2017. Its source EUI of 7.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 81,224 kWh of electricity for the year.
Which law requires MERCER ARENA - SEATTLE CENTER to report its energy use?
MERCER ARENA - SEATTLE CENTER 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:111:2017). 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.
