How has Cloverdale Business Park (Bldg A)'s energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Cloverdale Business Park (Bldg A), covering report years 2015–2025. Site EUI moved from 41.1 kBtu/ft² (2015) to 63.5 kBtu/ft² (2025), an 55% increase. Reported emissions went from 39 tCO₂e to 66 tCO₂e over the same span (up 69%).
What does a site EUI of 63.5 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. Cloverdale Business Park (Bldg A)'s 63.5 kBtu/ft² across 31,360 sq ft works out to about 2 billion Btu (584 MWh-equivalent) in 2025. Its source EUI of 110.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 227,336 kWh of electricity and 11,997 therms of natural gas for the year.
Which law requires Cloverdale Business Park (Bldg A) to report its energy use?
