How has C & H Company (Storage Warehouse)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for C & H Company (Storage Warehouse), covering report years 2015–2025. Site EUI moved from 6.4 kBtu/ft² (2015) to 10.9 kBtu/ft² (2025), an 70% increase. Reported emissions went from 6 tCO₂e to 11 tCO₂e over the same span (up 91%).
What does a site EUI of 10.9 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. C & H Company (Storage Warehouse)'s 10.9 kBtu/ft² across 22,200 sq ft works out to about 0.2 billion Btu (71 MWh-equivalent) in 2025. Its source EUI of 13.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,308 kWh of electricity and 2,096 therms of natural gas for the year.
Which law requires C & H Company (Storage Warehouse) to report its energy use?
C & H Company (Storage Warehouse) 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:25554:2025). 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.
