How has Campus Apt's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Campus Apt, covering report years 2015–2025. Its ENERGY STAR score was 88 in both 2015 and 2016. Site EUI moved from 31.8 kBtu/ft² (2015) to 37.2 kBtu/ft² (2025), an 17% increase. Reported emissions went from 20 tCO₂e to 22 tCO₂e over the same span (up 10%).
What does a site EUI of 37.2 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. Campus Apt's 37.2 kBtu/ft² across 24,680 sq ft works out to about 0.9 billion Btu (269 MWh-equivalent) in 2025. Its source EUI of 77.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 160,588 kWh of electricity and 3,710 therms of natural gas for the year.
Which law requires Campus Apt to report its energy use?
Campus Apt 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:20264:2025). 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.
