Named after Amazon’s first dog, Rufus the Corgi, Rufus 2.0 is Amazon’s corporate headquarters. It is a three-tower campus that spans five city blocks in Seattle’s Denny Triangle neighborhood. EEI commissioned all of the buildings, including the iconic conservatory spheres. 

Amazon’s corporate expansion in Seattle necessitated adjacent buildings that meet the company’s needs. There are numerous offices and shared spaces and amenities, including dining, retail, a library, and a fitness center. Amazon’s leadership pursued a unique vision for this campus that mixed innovative workspaces with sustainability features and a healthy indoor environment. 

One of our team’s most challenging features was the district energy system that uses waste heat from a data center condenser water loop piped under the street to six heat recovery chillers. It creates district heating for five city blocks in the winter, and adjacent buildings use the piping to circulate cooling in those loops in the summer. Each building has thermal energy storage tanks used to store cold water and act as building pony chillers. We successfully commissioned this feature and the rest of the systems.
