How has Discovery Park Condominium's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Discovery Park Condominium, covering report years 2015–2025. Site EUI moved from 23.9 kBtu/ft² (2015) to 24.9 kBtu/ft² (2025), an 4% increase. Reported emissions went from 3 tCO₂e to 3 tCO₂e over the same span (up 1%).
What does a site EUI of 24.9 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. Discovery Park Condominium's 24.9 kBtu/ft² across 20,930 sq ft works out to about 0.5 billion Btu (153 MWh-equivalent) in 2025. Its source EUI of 69.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 152,445 kWh of electricity for the year.
Which law requires Discovery Park Condominium to report its energy use?
Discovery Park Condominium 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:21563:2025). 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.
