How does Central Park compare with other office buildings in Seattle?
The latest disclosures cover 497 office buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 47.4 kBtu/ft² is roughly in line with the average of 44.8 kBtu/ft². Its emissions intensity of 1.1 kgCO₂e/ft² is about 54% above the group average of 0.7 kgCO₂e/ft².
At 61,419 sq ft, it is about 69% below the average floor area of 196,452 sq ft for those buildings. It was built in 1985, 20 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has Central Park's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Central Park, covering report years 2015–2025. Its ENERGY STAR score went from 30 in 2015 to 35 in 2017 (+5 points); its best year on file was 2016, at 36. Site EUI moved from 30.4 kBtu/ft² (2015) to 47.4 kBtu/ft² (2025), an 56% increase. Reported emissions went from 11 tCO₂e to 66 tCO₂e over the same span (up 475%).
What does a site EUI of 47.4 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. Central Park's 47.4 kBtu/ft² across 61,419 sq ft works out to about 2.9 billion Btu (853 MWh-equivalent) in 2025. Its source EUI of 101.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 525,652 kWh of electricity and 10,772 therms of natural gas for the year.
Which law requires Central Park to report its energy use?
Central Park 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:20500:2025). 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.
