Ken Warren, P.E., capital project manager, Port of Seattle (Wash.), received a first place 2016 ASHRAE Technology Award in the new industrial facilities or processes category for the Sea-Tac Airport Pre-Conditioned Air project. The building is owned by the Port of Seattle.

The Port’s Century Agenda sets a vision of reducing carbon emissions and air pollutants, increasing energy conservation, being socially and fiscally responsible and exceeding customer expectations. Its Pre-conditioned Air project is an important step in meeting an agenda objective of being the greenest, most energy efficient port in North America.

The system includes a pre-conditioned air plant (PCAP), piping and air handlers to provide cooling and heating for airplanes during boarding and deplaning to reduce costs for airlines, improved air quality, reduced noise and increased energy efficiency. The PCAP delivers sub-cooled glycol/water through 15 miles of piping to each of the 73 airplane gates in the existing facility, to serve the complete airplane HVAC&R needs. The system allows airplanes to shut off their jet-fueled on-board auxiliary power units (APUs), resulting in jet fuel savings and reductions in carbon dioxide and other gas emissions.

The reductions realized through the project include annual savings of:

  • An estimated five million gallons in fuel; a $15 million savings in airline fuel costs
  • 40,000 metric tons of greenhouse gases, the equivalent of removing 8,000 cars from the road
  • 73 tons of nitrogen oxides
  • Noise pollution from aircraft parked at the gates operating their APUs

The ASHRAE Technology Awards recognize outstanding achievements by members who have successfully applied innovative building design. Their designs incorporate ASHRAE standards for effective energy management and indoor air quality. Winning projects are selected from entries earning regional awards.

First place awards will be presented at the ASHRAE 2016 Winter Conference, Jan. 23-27, Orlando, Fla.
