What does a site EUI of 22.6 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. 1015 2nd Avenue Bldg's 22.6 kBtu/ft² across 232,045 sq ft works out to about 5.2 billion Btu (1,537 MWh-equivalent) in 2025. Its source EUI of 46.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 860,440 kWh of electricity for the year.
Which law requires 1015 2nd Avenue Bldg to report its energy use?
1015 2nd Avenue Bldg 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:50736:2025). 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.
