How has Plaza Del Sol's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Plaza Del Sol, covering report years 2015–2025. Its ENERGY STAR score went from 72 in 2015 to 74 in 2021 (+2 points); its best year on file was 2020, at 87. Site EUI moved from 40.8 kBtu/ft² (2015) to 28.5 kBtu/ft² (2025), a 30% decrease. Reported emissions went from 52 tCO₂e to 29 tCO₂e over the same span (down 43%).
What does a site EUI of 28.5 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. Plaza Del Sol's 28.5 kBtu/ft² across 82,519 sq ft works out to about 2.4 billion Btu (689 MWh-equivalent) in 2025. Its source EUI of 71.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 520,246 kWh of electricity and 3,607 therms of natural gas for the year.
Which law requires Plaza Del Sol to report its energy use?
Plaza Del Sol 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:28008:2025). 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.
