Aircraft at Sea-Tac Airport are now heated and cooled at the gate from a central plant in the terminal.
Central pre-conditioned air project
General contractor: Lydig Construction
Owner/developer: Port of Seattle
Primary designer: Stantec
Interior aircraft temperatures must be maintained at 68 to 70 degrees and are typically controlled by systems that burn expensive jet fuel.
The pre-conditioned air project is a new system of chillers, heaters and pipes that conditions aircraft interiors from a central plant in the terminal at Seattle-Tacoma International Airport. The new system’s financial and environmental benefits are significant, generating annual savings of nearly $14 million.
The most challenging part of this project was the piping installation. Glycol piping is large and very heavy because it is full of liquid. This project included installation of 15 miles of piping, reaching 73 gates.
The project team designed each and every pipe route, hanger location and many other components that meander through a sea of existing conveyor belts and utility infrastructure. Additionally, the team focused on design details that cut several million dollars in potential construction costs.
