How has Hobson Place Campus's energy performance changed over time?
BuildingCensus holds 5 Seattle disclosures for Hobson Place Campus, covering report years 2021–2025. Its ENERGY STAR score went from 100 in 2021 to 87 in 2025 (-13 points); its best year on file was 2021, at 100. Site EUI moved from 19.4 kBtu/ft² (2021) to 36.0 kBtu/ft² (2025), an 86% increase. Reported emissions went from 47 tCO₂e to 70 tCO₂e over the same span (up 49%).
What does an ENERGY STAR score of 87 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Seattle, 69% of scored buildings are at 75 or above.
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. Hobson Place Campus's 36.0 kBtu/ft² across 160,028 sq ft works out to about 5.8 billion Btu (1,688 MWh-equivalent) in 2025. Its source EUI of 90.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,304,894 kWh of electricity and 8,426 therms of natural gas for the year.
Which law requires Hobson Place Campus to report its energy use?
Hobson Place Campus 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:50718:2025). 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.
